Top Suppliers Furan Resin Sand Casting - Custom Bronze Sand Casting – RMC Foundry

Bronze is a kind of copper-based alloy with Tin. The hardness and strength of bronze increase with an crease in Tin content. The ductility is also reduced with the increase in tin percentage above 5. When aluminium is also added (4 to 11%), the resulting alloy is termed aluminium bronze, which has a considerably higher corrosion resistance. Bronzes are comparatively costly compared to brasses due to the presence of tin which is an expensive metal. At RMC Foundry, the bronze could be cast by sand casting, investment casting and other casting processes if required. The usage of bronze castings is not as wide as brass casting, however, for some special applications, the bronze should be used due to their special performances.

Like many other alloys, copper and copper-based alloys can be formed into highly complex parts, making them ideal for the sand casting and 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 production part. However, the pure copper is not usually cast.
