Our Products
Our offered Product range includes White Metal Ingots and White Metal Alloys Ingot.
White Metals/ Antifriction Bearing Alloys Ingots & Castings are cast as per IS:25-1979 Reaffirmed 2003 Specification. White Metals are cast as per 10 Grades of Anti Friction Bearing Alloys. The ingots manufactured are homogeneous and free from nonmetallic inclusions and have a clean appearance and fine grain structure. White Metal alloys are used for lining of petrol & diesel engine bearing crossheads in steam engine and other bearings used at high speeds. They are used for repair jobs in mills and marine installations, for underwater applications as a bearing alloy and gland packings, for lining of bearings required for medium speeds such as centrifugal pumps, circular saws, converters, dynamos and electrical motors, for low-speed bearings such as pulp crushers, concrete mixers and rope conveyors. They are again used for heavy duty bearings, rolling mill bearing in sugar, rubber, paper, steel industries, bearings for diesel engines, crossheads in steel engines, turbines etc. They are used for mill shaftings, railway carriage & wagon bearings and as a thin line overlay on steel strips where the white metal lining material is 0.076mm thick. The 10 grades of Anti Friction bearing alloys with chemical compositions are tabulated below: -

White Metal Alloys have low friction and wearing properties making them ideal for use in machinery were smooth and reliable operation is critical. They have strong inertness and extreme hardness applied in service severe conditions excellent strength and high operating temperatures. White Metals are a family of alloys that contain Tin, Antimony and Copper along with other elements like Lead & Arsenic. They are commonly used in large machinery applications such as turbines and generators. Babbitt Metal contains Tin, Antimony & Copper with smaller amounts of elements such as Lead & Zinc. Babbitt Metal is commonly used in high speed & heavy load bearing applications such as automotive engines and heavy machinery. The special grades of white metals are tabulated for their properties are as follows: -
