Study Notes
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.
