Bearing Metals

Babbitt Metal

The original alloy devised by Babbitt himself was 4 lb copper, 8 lb antimony, and 24 lb tin (11.1% copper, 22.2% antimony, 66.6% tin). The name has come to mean many soft lining and anti-friction bearing metals as listed in our products list under Bearing Metal.

Bearing Metal

Bearing metal is also known as Babbitt Metal, White-metal, and Anti-friction alloy.

The grades we make as standard are:

  • A metal – conforming to ASTM B23 no. 2:  Highly ductile, fatigue resistant, used to take heavy loads at high speeds and for massive bearings and large con-rod bearings not subjected to shock. Used in a wide range of applications including setting knife guides for sawmills.  People restoring old cars often seek bearing or Babbitt metal, and this is the one they need.

  • A1 – conforming to ASTM B23 no. 3: Special tin-based alloy for use in crushers. Used for heavy duty quarry and metallurgical crushers.

  • AR: Best quality whitemetal for heavy-duty, shock-loaded conditions and recommended for diesel engines.

  • 400: Highly ductile and corrosion resistant underwater metal, recommended where there is contact with salt water, such as stern shafts.

  • No.4: Lead-based lower cost alloy widely used in windmills.

Other formulae are made to customer specification.

Assays are available if required.

White-metal

This is a generic name given to alloys of tin, lead and antimony and all copper-zinc alloys containing more than 60% zinc. It includes pewter, soft solder, Britannia metal, type-metals, antifriction alloys, bearing alloys and Babbitt metal.
