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.

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 ...
The white metals are a series of often decorative bright metal alloys used as a base for plated silverware, ornaments or novelties, as well as any of several lead-based or tin-based alloys used for things like bearings, jewellery, miniature figures, fusible plugs, some medals and metal type. [1]
Britannia metal (also called britannium, Britannia ware, [1] or Vickers White Metal [2]) is a specific type of pewter alloy, favoured for its silvery appearance and smooth surface. The composition by weight is typically about 92–93% tin , 5–6% antimony , and 2% copper .

A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
