Introduction to Brass, Bronze, and Red Copper

Brass, bronze, and red copper are essential non-ferrous metals known for their excellent conductivity, corrosion resistance, and aesthetic appeal. These alloys are widely used in industrial, electrical, and decorative applications due to their mechanical properties and durability.

Specific Types of Brass, Bronze, and Red Copper (ISO Standards)

Brass, bronze, and red copper are classified based on their composition and mechanical properties. Common ISO-standard types include:

Brass (Cu-Zn Alloys):
- C260 (Cartridge Brass): High ductility and corrosion resistance.
- C360 (Free-Cutting Brass): Excellent machinability, used in precision components.
Bronze (Cu-Sn & Cu-Al Alloys):
- C510 (Phosphor Bronze): High strength and wear resistance.
- C954 (Aluminum Bronze): Superior corrosion resistance and hardness.
Red Copper (Pure Copper):
- C101 (Oxygen-Free Copper): High electrical conductivity.
- C110 (Electrolytic Tough Pitch Copper): Excellent thermal conductivity and corrosion resistance.
