Alloy is sometimes a result of the sizes of the atoms in the alloy, because larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors, helping the alloy resist deformation. Sometimes alloys may exhibit marked differences in behavior even when small amounts of one element are present. For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. Some alloys are made by melting and mixing two or more metals. Bronze, an alloy of copper and tin, was the first alloy
Nickel Babbitt Babbitts high in tin content, consist of a relatively soft, solid matrix of tin in which are distributed hard copper-tin and tin-antimony cuboids. Babbits are often employed as a thin surface coating to obtain the advantage of their good rubbing characteristics. Nickel Babbitt Babbitt refers to a bearing alloy consisting typically of tin, lead, antimony, and copper. "XXXX Nickel" is a trade name for such an alloy that also contains a small percentage of nickel. Isaac Babbitt was issued the first patent for an alloy that was excellent for making bearings. The word Babbitt has been applied to many alloys
