Zinc Aluminum Alloys

Intro

Alloys that met at low temperature (431C) [1] and have 60ksi tensile strength. They display the low melting point slightly smaller than that of zinc, with strength significantly greater than that of aluminum (45 ksi). [2].

ZA alloys not only show the best melt/strength properties of each component metal. They show IMPROVED melt point (430 compared to 660C for Aluminum) - strength (30% stronger)properties compared to their components.

As such, ZA are magical ingredients for the Desktop Foundry.

Machinability

• ZA 12 is machinable and 120 Brinell Hardness, same as mild steel
