Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.Bronze is harder than copper as a result of alloying that metal with tin or other metals. Bronze is also more fusible (i.e., more readily melted) and is hence easier to cast. It is also harder than pure iron and far more resistant to corrosion. The substitution of iron for bronze in tools and weapons from about 1000 bc was the result of iron’s abundance compared to copper and tin rather than any inherent advantages of iron.Our standard lines of Bronze Bushings and Bronze Sleeve Bearings are always being produced to maintain our Service Center inventory levels.
