Bronze Sand Castings
Leitelt Brothers Inc. has extensive experience with pouring bronze sand castings. We specialize in production run orders ranging in size from 1 ounce up to 350 pounds.
Bronze alloys typically consist of 80 to 90% Copper (Cu) and 5 to 15% Tin (Sn) with other elements such as Zinc (Zn), Lead (Pb) and Iron (Fe) making up the balance. Manganese Bronze and White Manganese Bronze are the exceptions to the rule with typically 55 to 65% Cu, 20 to 25% Zn, 1 to 5% Manganese, 1 to 5% Fe (Iron) and the balance made up of Al (aluminum).
