SAE 863 Sintered Bronze Alloy
SAE 863 is an oil-impregnated sintered iron-copper alloy, known for its high strength and wear resistance. It is used in heavy-duty applications such as bearings and bushings, where minimal lubrication is required.
Common applications include:
- Bearings and bushings in heavy machinery
- Industrial components
- Agricultural equipment
Technical Details
SAE 863 is composed of 18-22% copper and 76-80% iron, with approximately 19% oil by volume.
