Non Ferrous Metals - IntroductionNonferrous metals and their
alloys do not contain iron as a principle ingredient, although they
may contain small percentages. These include the radioactive metals
uranium, thorium, and plutonium that are used as nuclear fuels.
Copper and its Alloys
Bronze is an alloy consisting primarily of copper and the
addition of other metals (usually tin) and sometimes arsenic,
phosphorus, aluminium, manganese, and silicon. These additions
produces an alloy much harder than copper alone.Various kinds of
bronze are used in many different industrial applications. Phosphor
bronze is used for ships' propellers, musical instruments, and
electrical contacts. Bearings are often made of bronze for its
friction properties. It can be filled with oil to make the
proprietary Oilite and similar material for bearings. Aluminium
bronze is very hard and is used for bearings and machine tool
ways.
