Casting the ZA-12 zinc-aluminum alloy (Zn-11Al-0.8Cu) in graphite molds produces parts that are harder, stronger, and more durable than those cast of aluminum, brass, bronze, or plastic.

Based on total acquisition cost (cost-per-part times volume plus tooling costs), the permanent graphite mold/ZA-12 casting process is an economical alternative to CNC machining, die casting, sand casting, and investment casting.

Furthermore, the high accuracy and lustrous surface finish of ZA-12 parts virtually eliminate the need for additional finishing, further reducing overall production times and costs.
