The most common zinc alloy, ZAMAK 3, satisfies most die casting needs with it's high strength, hardness and low melting point. The other ZAMAK alloys; ZAMAK 2, ZAMAK 5, and ZAMAK 7; have a similar range of Aluminum but differ with their Magnesium and Copper ranges... LEARN MORE		Slush Casting Alloys Slush Casting Alloy contains approximately 5% Aluminum and 95% Zinc. It is used primarily for the use of hollow castings. It is the process of pouring slush alloy into a split metal mold and then immediately (time depending on the thickness of the wall desired) inverting the mold... LEARN MORE
