    - Copper is a non-ferrous metal. The different types of alloying elements used in copper alloys are zinc, tin, lead, manganese, phosphorous and beryllium.

    - These copper alloys are divided into two groups such as brass and bronze.

    - Copper alloyed with zinc is called as brass and if it is alloyed with other elements such as tin then it is called as bronze.

    - Copper alloys have high electrical conductivity and excellent bearing properties. These alloys have good corrosion resistance but have low strength. The strength of brass is increased and ductility decreases, if it contains 39% zinc.
