Babbitt metal


Babbitt metal

n.1. Any of several soft, silvery antifriction alloys composed of tin usually with small amounts of copper and antimony.2. See white metal.
[After Isaac Babbitt (1799-1862), American inventor who patented such an alloy.]

Babbitt metal

n (Metallurgy) any of a number of alloys originally based on tin, antimony, and copper but now often including lead: used esp in bearings. Sometimes shortened to: Babbitt [C19: named after Isaac Babbitt (1799–1862), American inventor]

Bab′bitt met`al


n. any of various alloys of tin with smaller amounts of antimony and copper, used as an antifriction lining for bearings. [1870–75; after Isaac Babbitt (1799–1862), U.S. inventor]

Babbitt

A soft metal used as a bearing lining. It was usually a mixture of tin (fifty parts), antimony (five parts), and copper (one part).

Babbitt metal


Babbitt metal,

an antifriction metal first produced by Isaac Babbitt in 1839. In present-day usage the term is applied to a whole class of silver-white bearing metals, or "white metals." These alloys usually consist of relatively hard crystals embedded in a softer matrix, a structure important for machine bearings. They are composed primarily of tin, copper, and antimony, with traces of other metals added in some cases and lead substituted for tin in others.

Babbitt Metal

 

an antifriction alloy based on tin or lead which is designed for lining bearings. Some types of babbitt metal contain antimony, copper, nickel, arsenic, cadmium, tellurium, calcium, sodium, magnesium, and so on.

Babbitt metal was invented in 1839 by I. Babbitt of the USA. Its high antifriction properties are due to its special heterogeneous structure, which is characterized by the presence of hard particles in the soft plastic base of the alloy. Babbitt metal has a low melting point (300° to 440° C) and good run-in qualities.

Babbitt metals based on tin are used for special-purpose bearings where improved toughness and a minimal coefficient of friction are required of the antifriction material. Compared with the lead-based babbitt metals, the tin-based metal has higher corrosion and wear resistance and thermal conductivity, as well as a lower linear expansion coefficient.

Lead-based babbitt metals can operate at a higher bearing temperature than the tin-based varieties. The former are utilized for lining the bearings of automobile, tractor, and milling-machine engines. Calcium plumbate babbitt metals are used to line the bearings of rolling stock and rail transport.
