Alloy nickel, but are not native to the Earth. One of the first alloys made by humans was bronze, which is a mixture of the metals tin and copper. Bronze was an extremely useful alloy to the ancients, because it is much stronger and harder than either of its components. Steel was another common alloy. However, in ancient times, it could only be created as an accidental byproduct from the heating of iron ore in fires (smelting) during the manufacture of iron. Other ancient alloys include pewter, brass and pig iron. In the modern age, steel can be created in many
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
