Aluminum Die Casting

Aluminum (Al) die castings are lightweight; yet withstand the highest operating temperatures of all the die cast alloys. Its strength, rigidity, and corrosive resistance offer significant heat dissipating advantages.

Aluminum is used in a broad range of networking and infrastructure equipment in the telecom and computing industries. Aluminum castings work for this application because RF filter boxes and housings require heat dissipation. It also provides EMI shielding, rigidity and durability with minimal weight for shields and housings for handheld devices. Because of aluminum’s excellent electrical performance and shielding properties, even in high-temperature environments, die casting aluminum is ideal for electronic connectors. Dynacast’s proprietary Thin Wall Aluminum Technology has made aluminum die casting an option for more applications.

Aluminum die castings improve automotive fuel efficiency by contributing to weight saving requirements. Our strength is in electronic applications, such as shields for telematic equipment and sensor housings, and safety-critical occupant restraint systems such as airbag housings and seat belt retractor spools.
