The 954 bronze square bar is an alloy that is made up with mostly aluminum. This makes it stronger than leaded-tin bronzes like C932 alloys. In fact, 954 bronze can be used in unit loads up to 50 percent higher than 932 bronzes. Even though it has very high strength, its ductility is rather low and it doesn’t do well with conforming or embedding. It also doesn’t have the anti-seizing properties that are offered by the 932 bearing bronze. The 954 bearing bronze has excellent resistance to corrosion and wear, which is why it’s frequently used in aviation and marine applications. It has superior strength when used in elevated temperatures. The tensile strength of this alloy is 90,000 psi and its yield strength is 37,000 psi.
Some of the applications it is used for that require great strength and corrosion resistance include wear plates, high strength clamps, machine parts, spur gears, worm gears, pump rods, bending tools, hydraulic valve parts, bushings, bearing and pickling hooks, to name a few. The machinability rating of this metal compared to 360 brass is 60 percent. This metal can be welded using joining techniques like brazing, soldering and other standard methods. However, it’s not recommended for oxyacetylene welding to be used on this metal.
When heat treating 954 bronze, it’s necessary to place one inch thick sections in 900 degrees F for one hour, followed by water quenching. Solution heat treatment and annealing require the same portions of metal and service times. Solution heat treatments have recommended temperatures between 1600 and 1675 degrees F, followed by water quenching and annealing should be done at between 1150 and 1225 degrees F.
