<p>Is your part in need of a surface coating but uncertainty about the best option prevails? Dynacast offers a diverse range of approximately thirty coatings, from chrome to electroless nickel and beyond. This comprehensive guide explores several key coating types, their characteristics, and suitable applications.</p><p>While this blog covers many options, Dynacast constantly introduces new surface coating solutions based on customer demands. If you require a coating not listed here, please contact our team.</p><p>For detailed information on specific <a href="/additional-capabilities/surface-finishes-and-plating" target="_self">surface finishing options</a>, consult with one of our design engineers.</p><h2>Chrome vs. Chromate</h2><p>Before looking into specific coatings, it's essential to differentiate between chrome and chromate. Chrome, derived from chromium, is an electroplated finish often associated with a shiny, metallic appearance, as seen on automobiles. Chromate, conversely, is a corrosion-resistant conversion finish rather than an additive coating. Dynacast provides numerous options for both chrome and chromate finishes.</p><h3>Chrome Plating</h3><p><strong>Bright Chrome:</strong> This mirror-like finish is familiar from <a href="/industries/automotive" target="_self">automobiles</a>, toys, and furniture. It offers corrosion protection, good wear life, and aesthetic appeal.</p><p><strong>Satin Chrome:</strong> Similar to bright chrome but with a duller finish. Both finishes involve rack plating with layers of copper, nickel, and chrome.</p><h3>Chromate with Zinc</h3><p>Zinc coatings are soft, decorative, and corrosion-resistant, protecting the base metal through sacrificial corrosion. Chromate application enhances corrosion protection.</p><ul><li><strong>Clear Chromate with Zinc:</strong> Exhibits a slightly iridescent blue hue.</li><li><strong>Yellow Chromate with Zinc:</strong> Imparts a yellow colour to the finished part.</li><li><strong>Black Chromate with Zinc:</strong> Provides a black finish.</li></ul><h3>Chromate without Zinc</h3><p>Black chromate without zinc is an inexpensive type of chromate. It’s typically used for parts that do not require a high amount of corrosion resistance. The coating goes directly onto a zinc die cast part. Yellow chromate parts are chemically milled and then chromated. This gives the part a dull finish. Both of these coating options are very thin and contribute no measurable thickness to the overall coating.</p><h3>Additional Chromates</h3><ul><li><strong>Olive Drab Chromate:</strong> Features a dark green finish and withstands 150 hours to white corrosion.</li><li><strong>Trivalent Chromate:</strong> Offers similar properties to traditional chromate without containing hexavalent chromium. Environmentally friendly with a bright blue colour, exceeding automotive specifications.</li></ul><h3>Nickel Plating</h3><p>Nickel plating, characterised by a yellowish-white colour and hard reflective finish, excels in wear resistance, solderability, and dimensional repeatability. Typically applied over copper on die castings, it also serves as a base layer for chrome plating.</p><ul><li><strong>Bright Nickel: </strong>The most common type but exercise caution with cold-forming due to potential ductility compromise.</li><li><strong>Watt's Nickel: </strong>Offers a satin finish and improved ductility, suitable for components requiring cold-forming.</li></ul><h3>Electroless Nickel</h3><p>Unlike electroplating, electroless nickel deposition does not require an electric current. This process yields exceptionally uniform coating thickness. It is widely used for its corrosion, wear, and abrasion resistance, along with ductility, lubricity, solderability, and hardness.</p><ul><li><strong>Low, Mid, and High Phosphorus: </strong>Varying phosphorus content influences properties.</li><li><strong>Black and Dark Blue Electroless Nickel: </strong>Primarily for decorative purposes.</li></ul><h3>Tin Plating</h3><p>Tin plating is ideal for components undergoing soldering during assembly. It offers excellent ductility, high solderability, and good surface coverage.</p><ul><li><strong>Matte Tin: Typically exhibits better solderability than bright tin.</strong></li><li><strong>Bright Tin: More commonly specified due to its superior appearance.</strong></li></ul><h3>Cobalt-Tin</h3><p>Resembling chrome in appearance and application, cobalt-tin involves copper/nickel plating followed by a cobalt-tin flash for a chrome-like finish. Known for its hardness and durability.</p><h3>Silver Plating</h3><p>Silver is valued for its low cost, despite tarnishing susceptibility to sulfur. It is primarily chosen for decorative, electrical conductivity, or thermal conductivity purposes. Offers high electrical and thermal conductivity, solderability, malleability, and ductility.</p><h3>Gold Plating</h3><p>Frequently used in<a href="/industries/consumer-electronics" target="_self">&nbsp;consumer electronics</a> due to its low contact resistance, solderability, and wire bonding capabilities. Alloying with cobalt enhances hardness and wear characteristics. Gold plating is available in four types: pure gold, hard gold, electroless gold, and immersion gold. Refer to the surface finishes page for details.</p><h3>Cadmium Plating</h3><p>Offers exceptional corrosion protection, approximately double that of zinc. Commonly used in aerospace, marine, and saltwater environments.</p><h3>Brass Plating</h3><p>Primarily used for decorative purposes, brass plating can be applied in bright or satin finishes and oxidised for an antique look. A lacquer topcoat can enhance coating longevity.</p><h3>Chem Film</h3><p>Chem film, also known as a conversion coating, is specifically designed for <a href="/metals/aluminum" target="_self">aluminium die castings</a>. The coating's colour can range from dark golden brown to light yellow, depending on various factors. Importantly, chem film does not alter the part's dimensions. There are two primary types of chem film: Class 1A and Class III, which are detailed on Dynacast's surface finishing page.</p><h3>Black E-Coat</h3><p>Black e-coat is a paint coating electrically applied to enhance a part's appearance and protect its surface.</p><h3>Anodising</h3><p>Anodising creates a non-conductive, protective coating that seals the part. Commonly used types include clear and black anodise. The final colour is influenced by the die casting alloy, with aluminium exhibiting minimal colour change. Anodising allows for various colour dyeing options, with black, blue, and red being the most popular. Two classes exist: Class 1, the natural colour without dye, and Class 2, dyed to a specified colour.</p><h3>Polyurethane Paint</h3><p>Renowned for its exceptional durability, polyurethane paint is often recommended for outdoor or exposed parts. It can be applied in smooth or textured finishes and typically air-dries, though baking accelerates the process.</p><h3>Powder Coating</h3><p>Powder coating surpasses standard wet paints in terms of thickness uniformity and colour consistency. The coating process involves curing at elevated temperatures, resulting in exceptionally tough finishes. Beyond its high hardness, powder coating is visually appealing, effectively conceals minor surface flaws, and delivers a durable, high-gloss appearance. Additionally, it is environmentally friendly, posing no air quality or hazardous waste concerns.</p><h3>Black Oxide</h3><p>Black oxide provides a protective, corrosion-resistant finish. While commonly associated with firearms, it also finds applications in spark plugs, furniture brackets, and mower blades. The black finish is chip-resistant and acts as an absorbent for oils or wax. Its economic nature, coupled with its ability to extend a part's service life and performance, makes black oxide a valuable coating option.</p>

Surface Finishing Options

<p>When designing components and selecting the right material, most engineers focus heavily on the weight of the material, which is why zinc is often overlooked for lightweight die casting applications. Many applications require parts to be lighter—especially in <a href="/industries/automotive" target="_self">automotive</a> and <a href="/industries/consumer-electronics" target="_self">handheld device</a> applications—so engineers choose aluminium or magnesium when zinc could actually be a more economical choice. At first glance, one would assume that zinc has no place in lightweight applications, but when we consider the entire die casting process, can the benefits outweigh the drawbacks for lightweight zinc components?</p><h2>Castability</h2><p>Zinc is the most fluid of all alloys; it is no wonder die cast manufacturers like working with it. What most engineers do not realise is that because of zinc’s greater fluidity, die castings can be made thinner, more intricate, and more complex, eliminating the need for secondary operations that are almost always necessary for aluminium and magnesium alloys. With less material used in thin-wall applications, parts automatically become lighter, creating savings in material cost and energy—during melting and recycling.</p><h2>Extended die life</h2><p>One of the biggest upfront costs in die casting is the investment in <a href="/additional-capabilities/tooling" target="_self">quality tooling</a>. The tools used in the die casting process are usually heat-treated steel. The cost of tooling varies depending on the size and complexity of the component as well as the tooling type—conventional or Multi-Slide. Due to the low melting temperature of zinc die casting alloy, dies for zinc parts can last up to 10 times longer than dies used for aluminium and about five times longer than dies used for magnesium. When designing high-volume, complex components, zinc</p><h2>Cycle time</h2><p>During the die casting process, molten metal is injected into the die to create the part. When the metal has solidified, the component is then ejected from the tool. Cooling time in the tool varies depending on the alloy and the size of the part and is often dictated by the size of the runner system. Zinc uses the hot chamber die casting process, which yields four to five shots per minute. Aluminium is a cold chamber die casting alloy, yielding only two to three shots per minute. Since cycle time can determine up to 60 percent of the final part cost, using a zinc die casting alloy could offer additional savings.</p><p><strong>Did you know that our proprietary Multi-Slide zinc die casting process can achieve upwards of 45 shots per minute?</strong></p><h2>Mechanical properties</h2><p>Standard zinc alloys are stronger than aluminium and magnesium alloys at room temperature. Strength is inherent in the alloy itself and does not require secondary processing like most aluminium alloys—this saves on the overall cost per part.</p><p>EZAC is an alloy offered by Dynacast that is stronger and harder than any other die casting alloy. It is approximately 2.5 times stronger (yield strength) and 1.5 times harder (Brinell) than the most common aluminium die casting alloy, A380. With its zinc characteristics, EZAC is a great option for those seeking a high-strength, creep-resistant alloy.</p><table><tbody><tr><td><p><strong>Material</strong></p></td><td><p><strong>Alloy</strong></p></td><td><p><strong>Yield strength (0.2%)</strong></p></td><td><p><strong>Hardness</strong></p></td></tr><tr><td>&nbsp;</td><td>&nbsp;</td><td><p>PSI X 10^3</p></td><td><p>Brinell (HB)</p></td></tr><tr><td><p>Zinc</p></td><td><p>Zamak 3</p></td><td><p>32</p></td><td><p>82</p></td></tr><tr><td><p>Zinc</p></td><td><p>EZAC</p></td><td><p>57</p></td><td><p>120</p></td></tr><tr><td><p>Aluminium</p></td><td><p>A380</p></td><td><p>23</p></td><td><p>80</p></td></tr><tr><td><p>Magnesium</p></td><td><p>AZ91D</p></td><td><p>23</p></td><td><p>63</p></td></tr></tbody></table><p>Try our interactive metal selector tool to compare the physical and mechanical properties of other die cast alloys.</p><p>Dynacast has over 80 years of experience in the die casting industry.
