China Gold Supplier for Steel Shell Casting Foundry - Custom Investment Casting Brass Flange – RMC Foundry

OEM custom brass casting flange and other investment casting brass components play an important role as bearing bushings, gears, valve and pump bodies, water pipes and other mechanical ndustries which need performance of corrosion resistance and wearing resistance. 

As the most used copper-based alloy, brass can be formed into highly complex casting parts, making them ideal for the investment casting process. Constant cost fluctuations can make these materials very price sensitive, making waste very costly, especially when considering CNC machining and/or forging as a manufacturing process to produce your cast parts. However, pure copper is not usually cast. Casting brass has higher mechanical properties than bronze, but the price is lower than bronze. 

Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Brass is a copper alloy with zinc as the main element. As the zinc content increases, the strength and plasticity of the alloy increase significantly, but the mechanical properties will decrease significantly after exceeding 47%, so the zinc content of brass is less than 47%. In addition to zinc, cast brass often contains alloying elements such as silicon, manganese, aluminum, and lead.
