SAE 841 Sintered Bronze Alloy
SAE 841 sintered bronze is an oil-impregnated alloy, known for its self-lubricating properties. It is commonly used in bushings, bearings, and industrial machinery where conventional lubrication is difficult to provide.
Typical applications for SAE 841 include:
- Bearings for machinery and equipment
- Automotive and agricultural components
- Home appliances and office machinery
SAE 841 is available in solid and hollow bar forms. It offers excellent wear resistance and durability.
Technical Details
SAE 841 is composed of 87.5-90.5% copper, 9.5-10.5% tin, and 1% iron, with oil making up about 19% of its volume.
