Tin
is a silvery white metal with a specific gravity of 7.29
and a melting point of 232° C. It has a brilliant lustre
and when polished, it has a high light reflectivity. The
metal is highly resistant to corrosion and fatigue, and
alloys well with many other metals particularly with
copper (bronze) and lead (solder). Chemically, the most
outstanding property of tin is its ability to resist
attack by air and by many of the organic acids, including
those found in food of various kinds.
In brief, tin’s
outstanding physical and chemical properties include
corrosion resistance, non-toxicity, lubricity,
malleability, alloyability with many metals, a low melting
point, ductility, low coefficient of friction, solderbility, low vapour pressure, adaptability to
compounding and processing, wetting and adhering
potential and electrodeposition compatibility. |
