Applications
932 Bearing Bronze is a high strength alloy with good wear and corrosion resistance due to its tin, iron, and zinc content. It is most commonly used for bearings, bushings, and thrust washers. 932 Bronze is not heat treatable.
954 Bearing Bronze (also known as aluminum bronze) contains at least 10% aluminum, which adds to its strength and weldability. Similar to 932 Bearing Bronze, it is commonly used for bearing and bushings.
544 Bearing Bronze (also known as phosphor bronze) offers excellent fatigue and stress-cracking resistance. The material is best utilized in designs for valves and shafts.

Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
Is Bronze easy to machine?
Bronze has extremely high machinability, with 642 bronze having the highest of all brass and bronze alloys. It’s known for high strength, ductility, thermal conduction, hardness, low friction properties and corrosion resistance. External CNC machining can be performed at relatively fast speeds, whereas slightly slower speeds are recommended for boring or drilling and very slow speeds for reaming.
What are the best grades of bronze for CNC machining?
Different grades of bronze can be used in many industries. 642 bronze is ductile, resistant to corrosion, fatigue, and galling, and has the highest machinability of all brass and bronze alloys. PB1 Phosphor bronze also has good machining qualities and is free machining, yet very tough.
Are coolants necessary for machining bronze?
When CNC machining bronze it can reach high temperatures when drilling and turning so the use of a coolant is recommended.
