ductile at 2120, when it can be drawn out into wire which
is not very tenacious; it melts at 4420, and at a higher
temperature burns with a brilliant white light. Air and
moisture act on tin very slightly. The peculiar properties
of tin, especially its malleability, its brilliancy and
the slowness with which it rusts make it very serviceable.
With other metals it forms valuable alloys, as bronze, gun
metal, bell metal, pewter and solder. It is not easily
oxidized in the air, and is used chiefly to coat iron to
protect it from rusting, in the form of tin foil with
mercury to form the reflective surface of mirrors, and in
solder, bronze, speculum metal, and other alloys. Its
compounds are designated as stannous, or stannic. Symbol
Sn (Stannum). Atomic weight 117.4.
