Pewter
Pewter, a term referring to a wide range of alloys that consist primarily of tin, has been used for thousands of years in a wide variety of applications, most recently ranging from gift and hollowware to industrial and electronic solders. It is available in ingot form for casting, or in sheet form for spinning and forming. Pewter has a low melting point, is easy to cast or form, and is ductile, making it easy to work without annealing. Many alloys of "pewter" contain lead and/or cadmium by design, however, the use of these alloys has diminished due to safety concerns.
Oster Pewter
Oster Pewter originated in 1974 as product line within the A. J. Oster Company. In the mid 1980's, British industrial conglomerate Cookson PLC bought the A. J. Oster Company, then sold the name and the brass division to Olin Corporation in the early 1990's, but retained the white metal and pewter product lines under the name Oster Alloys, a dba of Fry's Metals.
In 2002, Callico Metals, Inc. acquired the assets of the rolled sheet pewter product line from Cookson. This stand-alone, privately held company now does business as Oster Pewter.
