What is Brass casting？
Brass is an alloy mainly made of copper and zinc. Copper is the base metal. Zinc is the main alloying element. According to different performance requirements, a small amount of other elements can be added to brass. Such as Pb, Sn, etc. The addition of these elements can further improve the mechanical properties and machinability of brass.
Brass castings refer to parts or products made of brass through casting processes. As a leading copper foundry in China. We have professional technology to make copper castings of various sizes. Our state-of-the-art equipment and years of casting experience enable us to meet the wide range of applications of brass. Please trust JC Casting to provide you with the best brass solutions according to your needs.

| Comparison items | Brass castings (taking copper-zinc alloy as an example) | Castings made of other materials |
| Appearance and decorativeness | Naturally presents a golden metallic luster. Can be used directly as a decorative piece (such as handicrafts, architectural hardware) Or can be enhanced in appearance through electroplating, polishing and other processes | Cast iron: gray appearance, requires paintingAluminum alloy: The surface can be oxidized and colored, but the glossiness is not as good as brassStainless steel: Silvery white appearance, strong decorativeness but high cost |
| Wear resistance and friction reduction | It has good friction reduction properties and is not easy to stick when rubbing against steel. It is suitable for manufacturing friction parts such as bearings and gears. Brass containing elements such as tin and lead (such as tin bronze) has better wear resistance. | Cast iron: Good wear resistance, but needs to be used with lubrication.Aluminum alloy: Poor wear resistance, usually requires surface treatment (such as hard anodizing).Stainless steel: Average wear resistance, high friction coefficient. |
| Processability | Excellent casting fluidity. Suitable for molding complex thin-walled parts. High surface finish of castings Can be processed by sand casting, metal mold casting and other processes. And good cutting performance (leaded brass is easier to cut) | Cast iron: Good fluidity. But the wall thickness of the casting should not be too thin. Average cutting performanceAluminum alloy: Excellent fluidity. But easy to produce poresStainless steel: Poor casting fluidity. Requires high temperature casting. Difficult to process |
