Overview

Why choose zinc?

Despite being heavier than other alloys, zinc’s lower melting point reduces energy consumption during production, and its suitability for die casting often replaces more complex and costly processes.

  • 150+ conventional machines from 20t to 350t
  • 450+ Multi-Slide machines from 4t to 65t
  • Cost-effective
  • Enhanced strength and hardness

Alloy properties and applications

Zamak 2
Zamak 2
Zinc Alloy 2, also known as Kirksite or Zamak 2 (ASTM AC43A), has the highest strength and hardness in the Zamak family.
Zamak 3
Zamak 3
Zamak 3 (ASTM AG40A), or Zinc Alloy 3, is the most widely used zinc alloy in North America and is usually the first choice when considering zinc for die casting for several reasons.
Zamak 5
Zamak 5
Zamak 5 (ASTM AC41A), or Zinc Alloy 5, is the most widely used zinc alloy in Europe.
Zamak 7
Zamak 7
Zamak 7 (ASTM AG40B), or Zinc Alloy 7, is a modification of Zamak 3. It is a high-purity alloy with lower magnesium content and a tighter impurity specification. This results in improved casting fluidity, ductility and surface finish.
Zamak 8
Zamak 8
ZA-8, or zinc-aluminium alloy, contains significantly more aluminium than the Zamak group of alloys. ZA-8 contains approximately 8.4% aluminium and is the only ZA alloy that can be hot-chamber die cast, an important consideration when selecting a material for a component.
ACuZinc5
ACuZinc5
ACuZinc5 is an alloy researched and developed by General Motors. It is best known for its creep performance, surface hardness and lubricity.
EZAC
EZAC
EZAC is a hot-chamber zinc die casting alloy with superior creep resistance, high yield strength and high hardness.
Zamak 27
Zamak 27
ZA-27, or zinc-aluminium alloy, contains significantly more aluminium than the Zamak group of alloys. The number 27 represents the approximate percentage of aluminium.
BERIC
BERIC
Superior zinc-based alloy in terms of wear resistance, tensile strength, hardness and mechanical properties.
Kayem
Kayem
Kayem is a zinc-based alloy primarily composed of zinc, aluminium and copper. It is often referred to as Mazak 2.
ZP0410
ZP0410
ZP0410 is a reliable and versatile zinc alloy that provides a good balance of properties for many die casting applications in the automotive, electronics and hardware industries.
ZP0430
ZP0430
ZP0430 is often referred to as ZP2 or Zamak 2. It is a zinc alloy known for its exceptional strength and hardness.
