Major Application
-
- BEARINGS SN200, SN240 and SN305 are recommended for blending with copper for the production of bronze self- lubricating bearings and for bronze structural components. The specific grades are selected to have controlled dimensional change characteristics.
-
- FRICTION COMPONENTS SN200, SN240 and SN305 are used in metallic and nonmetallic friction material formulations to provide improved wear characteristics.
-
- ABRASIVE WHEELS SN305 and SN300 are used as matrix-bonding material for diamond and other abrasive wheels and cutting tools.
-
- CHEMICAL FORMULATIONS All the above grades listed above are widely used as catalysts in chemical formulations and for production of tin compounds.
