Product Description

The 959 bronze bar is popularly used in aviation and automotive industries. It has excellent hardness and strength. It also has great antifriction properties. Because of this, it is commonly used in other industries like industrial, appliance, aerospace, and applications that use bushings and bearings that are under medium speeds and loads and have ample lubrication. The 959 bronze is considered to be an all-purpose alloy. It has great performance in applications that require excellent abrasion resistance and strength. Some of the applications this metal is used for include gears, valve seats, worm drives, valve guides, wear strips, wear plates and bearings.

Other than being used for heavy duty bearing applications, 959 bronze alloys can and should be used against hardened steel shafts. Both the bearing and the shaft should have a fine surface finish provided through machining. Keep in mind that this alloy doesn’t tolerate dirty lubricants or misalignment.

This alloy is made with 12.8 percent aluminum, 4 percent iron and 80.2 percent copper. It has a tensile strength of 90,000 psi and yield strength of 50,000 psi. The elongation is 5 percent in two inches. The fabrication properties of this alloy are fair to excellent. Welding methods like soldering and brazing can be used for this metal, since it has good suitability for these joining techniques. Gas shielded arc welding is well suited for this alloy. However, coated metal arc welding was given a fair rating. Oxyacetylene is a welding method that is not recommended for use in 959 bronze alloys. The machinability rating of this metal is 70 percent compared to C360 brass (which is 100 percent).
