General Information About Bronze and Bronze Bars

Bronze bars are alloys consisting primarily of copper, usually with tin as the main additive. It is hard and tough, and it was so significant in antiquity that the Bronze Age was named after this metal.

There are many different bronze alloys, but modern bronze is typically 88% copper and 12% tin. Commercial bronze (90% copper and 10% zinc) and architectural bronze (57% copper, 3% lead, 40% zinc) are more properly regarded as brass alloys because they contain zinc as the main alloying ingredient. They are commonly used in architectural applications.

The lead content in bearing bronze bars are between 7 percent and 15 percent. High leaded tin bronze alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy 932 or C93200 is considered the workhorse alloy and is widely used in many bearing applications.

Bronze Grades:

954 and 959 Bronze

954, C95400, 959, C95900 are aluminum bronze which is the highest strength copper based alloy. These grades are available in rounds, tubes, and rectangles. Aluminum in conjunction with iron and nickel in C95500 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.

932 Bearing Bronze

932 Bearing Bronze offers good hardness and strength, as well as excellent anti-friction qualities. It is typically used in automotive, industrial, and aerospace applications. 932 Bearing Bronze is available in flats, rounds, or squares.

954 Aluminum Bronze

954 Aluminum Bronze is an all-purpose aluminum bronze alloy that offers exceptional performance in applications where high strength and abrasion resistance are required. Because of this, 954 Aluminum Bronze is typically used in valves and bearings.

959 Aluminum Bronze

Similar to 954 Aluminum Bronze, 959 Aluminum Bronze offers exceptional performance in applications where high strength and abrasion are required, and is typically used in strips/plates, gears, bearings, and valves.
