Brass Sand Casting

The first castings ever poured at Leitelt Brothers Inc. foundry, over 100 years ago, were from a brass alloy.

Brass is an alloy consisting mainly of copper (Cu) and zinc (Zn), up to 35% zinc is obtainable in certain alloys.

Red brass alloys typically consist 75 to 80% Cu and 5 to 15% Zn.

Yellow brass alloys typically have 65 to 75% Cu and 25 to 35% Zn.

The melting point of brass is in the range of 1650 – 1725 degree Fahrenheit. Find out more about our foundry capabilities and other value added services.
