Brass Alloys

Zinc is the main alloying element in brasses.
Zinc is commonly used to form alloys with copper.
Zinc contributes to the strength, corrosion resistance, and machinability of brass alloys.

Copper Alloys

Arsenical touch pitch copper is used to reduce the oxygen content and increase the conductivity of copper.
Phosphorus is present in deoxidized copper but not in oxygen-free copper.
Some copper alloys used in marine applications have high resistance to corrosion due to the presence of elements like zinc and aluminum.

Oxygen-Free Copper

The main reason for using oxygen-free copper is its high electrical conductivity and ability to withstand corrosion.
Oxygen-free copper is used in applications where high purity and conductivity are required.

Nonferrous Metals

Nonferrous metals are ideal for applications due to their properties like high corrosion resistance, low density, and high electrical conductivity.
Copper is widely used for electrical wire due to its low electrical resistivity.
The main grades of raw copper used for cast copper base alloys are electrolytic tough pitch (ETP) and oxygen-free copper.
Zinc is valued for its relatively low melting point and is widely used in die casting operations.
