Zinc alloys are versatile, cost effective materials which can be
used in a diverse range of applications. As precisely
formulated metal alloys, they offer the mechanical properties of
medium strength metals.
Overall, zinc alloys have significant advantages as casting
materials for small components, with excellent physical and
mechanical properties, castability and finishing characteristics.
Hot chamber die cast zinc alloys can be cast to tight tolerances,
complex detail, net shape, and the alloy's dimensional stability
ensures part-to-part consistency over long production runs.
Net shape manufacturing is one of the main advantages of hot
chamber die cast zinc alloys.
The most commonly used zinc alloys are ZAMAK™ 2, ZAMAK™ 3, ZAMAK™ 5, and ZAMAK™ 7. ACuZinc® is a high performance alloy with improved mechanical properties. These
alloy families offer higher tensile strengths than most aluminum and magnesium alloys,
higher yield strengths, greater impact resistance, higher Brinell hardness, and better
ductility.
- Zinc alloys facilitate higher die casting cycle
speeds versus aluminum and other metal alloys,
more complex shapes, thinner wall sections,
smoother surface finishes, and higher standards
of dimensional accuracy.
- Compared to plastic, zinc alloys are several
times stronger and many times more rigid.
Their mechanical properties compare favorably
with powdered iron, brass, and screw-machined
steel.
- Zinc has inherent EMI/RFI shielding properties.
FisherCast Global uses only high-grade zinc alloys certified for purity. Although these
materials are completely recyclable, scrap is never re-melted or re-used within our
process.
