List of copper alloys

Copper alloys are metal alloys that have copper as their principal component They have high resistance against corrosion The best known traditional types are bronze where tin is a significant addition and brass using zinc instead Both of these are imprecise terms having both been commonly referred to as lattens in the past Today the term copper alloy tends to be

METALS AND NON METALS ppt

Metals in the middle of the activity series like Zn Fe Pb are found as oxide sulphide or carbonate ores It is easier to obtain metals from their oxides than from their sulphides or carbonates So non oxide ores are converted into oxide form before reduction Non oxide ores can be converted into oxide form by roasting or calcination
