Tin Bronze alloys consist of copper-based materials with the major alloying element being tin. The presence of tin provides high mechanical properties, the offset being that the addition of tin adds to the metal cost.
C86500 is a copper alloy with nickel and iron. It is also called manganese bronze or naval bronze. It resists seawater corrosion and erosion, and is used for marine and naval applications. It has good strength and durability, and is easy to machine and weld.
