Zinc Casting Metal Alloy Rubber Mold Zinc

This metal is a casting alloy used mostly for centrifugal zinc castings in silicone rubber molds. The silicone molds used for this alloy are made to withstand the higher temperatures needed to cast this alloy opposed to pewter or tin based alloys. 

Casting temperatures start at just under 800 degrees F

Melting range 720-740 degrees f

Density lb/cu in .24

Brinell Hardness 95-100

The bar weighs between 22 to 23 pounds and will be broken into sections of about 7 inches each for shipping purposes.
