Abstract

An alloy for metallic reflectors consists of 60 per cent of tin, 30 per cent of lead, 4 per cent of copper, 2 per cent of stibnite, and 4 per cent of bismuth, with or without small amounts of aluminium, antimony, and compounds of the constituent metals. Specification 112,884, [Class 83 (i)], is referred to.
