** CASTING METAL BOLSTERS & BUTTCAPS**
What is Babbitt metal?
an antifriction metal first produced by Isaac Babbitt in 1839. In present-day usage the term is applied to a whole
class of silver-white bearing metals, or “white metals.” These alloys usually consist of relatively hard crystals
embedded in a softer matrix, a structure important for machine bearings. They are composed primarily of tin, copper,
and antimony, with traces of other metals added in some cases and lead substituted for tin in others.
What is Pewter?
Throughout it's long history pewter has had an almost infinite variety of compositions, even today there are still
numerous varieties produced. The only common factor is a relatively high tin content which is hardened by additions
of other elements. In most countries newly manufactured pewter is a lead free alloy usually being hardened with
additions of antimony and copper, containing over 90% tin. Other elements such as silver and bismuth are sometimes
used in. In the past pewter often contained lead but as awareness has grown into the harmful effects of lead it
should now have been eliminated. Modern pewter can be polished to a bright silver like finish or if preferred chemical
darkeners can be used to simulate the patinas associated with old pewter.
