Cast Brass

1. The chemical composition of cast brass
Brass is a Cu-Zn binary alloy with zinc as the main alloying element, commonly known as brass or ordinary brass. Ordinary brass has a certain strength, hardness and good casting properties, but wear resistance, corrosion resistance, especially corrosion resistance to flowing seawater, steam and inorganic acid is poor. Various alloying elements can usually be added to improve the mechanical, physical and chemical properties of brass, thus forming special brass suitable for different environments, such as navy brass, free-cutting brass, high-strength manganese brass and die-cast yellow. Copper and so on.
2. Casting process
There are some differences between the cast brass alloys due to melting point, fluidity, solidification shrinkage, melt sensitivity to gas, volatility and hot cracking tendency, so the applicable casting methods are also different.
The casting methods of cast brass mainly include die casting, sand casting, centrifugal casting, continuous casting and investment casting. Different alloys need to be targeted.
