A trade description for a pewter alloy containing a comparatively high proportion of antimony – typically 92% tin, 6% antimony and 2% copper.
This alloy was first introduced by Sheffield manufacturers in the second half of the 18th century and is a product of the industrial revolution. It was also known in its early days as white metal
As an alloy it has characteristics which permit articles to be made by cold-forming the alloy in sheet form (e.g. by spinning or stamping) rather than by casting. N.B. Some earlier books assert, possibly due to ignorance of the contents of the alloy, that Britannia Metal is not pewter!
