Pewter (/ ˈ p juː t ər /) is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. [1] In the past, it was an alloy of tin and lead, but most modern pewter, in order to prevent lead poisoning, is not made with lead.
Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic number 51. A lustrous grey metal or metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. [11]

A sort made from type metal. In printing, type metal refers to the metal alloys used in traditional typefounding and hot metal typesetting.Historically, type metal was an alloy of lead, tin and antimony in different proportions depending on the application, be it individual character mechanical casting for hand setting, mechanical line casting or individual character mechanical typesetting and ...
A small percentage of tin is added to zirconium alloys for the cladding of nuclear fuel. [103] Most metal pipes in a pipe organ are of a tin/lead alloy, with 50/50 as the most common composition. The proportion of tin in the pipe defines the pipe's tone, since tin has a desirable tonal resonance.
Babbitt metal or bearing metal is any of several alloys used ... Ford was known to use two 0.002" on each cap and Babbitt that was 86% tin, 7% copper, 7% antimony ...
While the term pewter covers a range of tin-based alloys, the term English pewter has come to represent a strictly-controlled alloy, specified by BSEN611-1 and British Standard 5140, consisting mainly of tin (ideally 92%), with the balance made up of antimony and copper. Significantly, it is free of lead and nickel. Although the exact ...
Antimony melts at 631 °C (1167 °F) [21] Platinum melts at 1768 °C (3215 °F), even higher than iron. [21] Native South Americans worked with it instead by sintering: they combined gold and platinum powders, until the alloy became soft enough to shape with tools. [25] [26]
