The 932 bronze rod is a copper-based alloy that has tin as its main additive. There are some bronzes that have other main additives, such as manganese, silicon, phosphorous or aluminum. What makes bronze a great product to use is its toughness, resistance to corrosion, strength, electrical conductivity and thermal conductivity. Bronze can be used in a wide array of applications. This grade of metal is considered a bearing bronze, which is actually the most commonly used grade for bearing and brushing applications. It has great machinability and can give applications longevity, due to its resistance to wear.
Bearing bronze metals are high leaded tin and is known to be the workhorse of the alloys in the bronze family. It also has great antifriction qualities. There’s no worry about dezincification because it isn’t subject to it. It also has reasonable resistance to corrosion typically caused by brine and sea water. This is why it’s frequently used in applications like pump and valve components. It can also be used for applications that have medium loads and speeds. The electrical conductivity of this metal is 12 percent of copper.
The applications that 932 bronze is typically used for include pump fixtures, fuel pump brushings, machine parts, insert bearings, thrust washers, machine tool bearings, gears, valves and valve components, fuel pump bushings, pump impellers, valves, and diesel engine wrist pins. The machinability rating of this alloy is 70 percent when compared to 360 brass. It’s not recommended for welding to be used on this product. However, brazing and soldering may be used, but the rating is low to fair. Brazing is done using temperatures with hot-short ranges, which is why it’s required to watch for stresses that may be caused during the process and cooling.
