About Copper, Brass, and Bronze

932 Bearing Bronze Tubes

Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Oil-Filled 841 Bearing Bronze Tubes

Powdered bronze is pressed and then impregnated with SAE 30 oil to make this material self-lubricating.

High-Temperature Graphite-Filled
841 Bearing Bronze Tubes

An excellent alternative to oil-filled bronze, graphite-filled bronze provides dry lubrication in temperatures as high as 700° F.

High-Strength 863 Bearing Bronze Tubes

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated.

Easy-to-Machine 936 Bearing Bronze Tubes

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

Weldable 954 Bearing Bronze Tubes

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. The strength of this material increases with heat treating.

Brass

Ultra-Formable 260 Brass Rectangular Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Ultra-Formable 260 Brass Round Tubes

Ultra-Formable 260 Brass Hex Tubes

High-Strength 330 Brass

Offering the highest yield strength of all our brass, 330 has a low lead content for a good balance of machinability and formability. It's used for fire station poles, pump cylinder lines, and plumbing accessories.
