Eastern Alloys, Inc. Slush Casting Alloy

Slush-cast alloy is a high-purity purpose-engineered product manufactured by Eastern Alloys. This alloy was developed to provide a high fluidity casting material capable of producing a good surface definition when cast in metal permanent molds or rubber molds. It contains approximately 5% aluminum and 95% zinc giving it a very short freezing range, and good fluidity. In the slush casting process, metal is poured into a slush-casting mold, allowed time to solidify along the mold wall only, and then poured out. The resulting "hollow" casting is then ejected and cooled. Its primary use is for decorative castings not subjected to high stress conditions, such as lamp bases.
