Metal alloys


For the production of objects, ornaments, household items it is often necessary to separate the components of a mixture to obtain pure substances, but other times it is necessary to mix substances to obtain some materials.

When in these mixtures one of the components is a metal a alloy.

Metal alloys have different characteristics from pure metals and can therefore be used to greater advantage over pure metal.

Copper and chromium alloys are used in electrical resistances such as shower resistors because the electrical conductivity decreases, in other alloys there is increased mechanical resistance, corrosion resistance, ductility etc.
