About Copper, Brass, and Bronze

Yield Strength:
840 Bearing Bronze: 7,000 psi
841 Bearing Bronze: 11,000 psi
Hardness: Not Rated
Temper: Not Rated
Heat Treatable: No
Specifications Met: ASTM B438

Powdered bronze is pressed and then impregnated with SAE 30 oil to make this material self-lubricating. Use it to make bearings and parts for hard-to-reach areas that would be difficult to access for lubrication, such as well pumps and turbine blades.

Tight-Tolerance Weldable 954 Bearing Bronze Bars

Yield Strength: 32,000 psi
Hardness: Not Rated
Temper: M07
Heat Treatable: Yes
Specifications Met: ASTM B505

These bars are precision ground on the top and bottom for a tight thickness tolerance of ±0.002". 954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears.

Tight-Tolerance High-Strength 863 Bearing Bronze Bars

Yield Strength: 62,000 psi
Hardness: Rockwell B95 (Medium)
Temper: M07
Heat Treatable: No
Specifications Met: ASTM B505

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated. These bars are a higher-strength alternative to tight-tolerance 954 bearing bronze bars. They’re precision ground on the top and bottom for a tight thickness tolerance, saving you the work of machining them.

Self-Lubricating Wear Plates

Impact causes these porous bronze plates to release a thin layer of oil on the surface to minimize friction. Often found on conveyor systems and fabricating machinery, use these plates where friction between two parts or materials is wearing down equipment to extend equipment life. They can be used outdoors.
