Bronze is a kind of copper-based alloy with Tin. The hardness and strength of bronze increase with an increase in Tin content. The ductility is also reduced with the increase of Tin. 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. Bronze and other copper-based alloys can be formed into highly complex 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 production part.
