According to the material, copper bushings can be divided into the following categories:
Tin bronze bushings

Characteristics: copper bushing has good wear resistance, corrosion resistance and excellent mechanical properties, especially suitable for medium load and medium speed working environment.
Application: Widely used in gears, bearings, connecting rods and other mechanical components that require wear and corrosion resistance.
Lead bronze bushings
Characteristics: Good anti-friction performance and excellent anti-seize performance, suitable for poor lubrication or high load working conditions.
Application: Commonly used in bearing bushings, plain bearings, guide bushings and other components that require good friction resistance.
Aluminium Bronze Bushings
Features: high strength, hardness and excellent corrosion resistance, able to maintain stable performance under high load and high temperature conditions.
Application: Widely used in high load bearings, gear bushings, propeller bushings and other components.

Brass bushing
Characteristics: Good electrical conductivity, thermal conductivity and corrosion resistance, suitable for light load and low speed application scenarios.
Application: Commonly used in electrical equipment, instrumentation in the bushing, guide sleeve and other components.
Zinc white copper bushings
Features: excellent corrosion resistance and high mechanical strength, especially suitable for marine environment or other corrosive environments.
Application: suitable for bearing bush and sealing bush and other parts in marine equipment and chemical equipment.
Silicon Bronze Bushings
Features: excellent corrosion resistance and fatigue resistance, as well as good weldability.
Application: Widely used in corrosion-resistant and fatigue-resistant parts in ships, aviation and electronic equipment.

Special Copper Alloy Bushings
Other copper alloys: such as manganese copper alloy, beryllium copper alloy, etc., with special physical and chemical properties, suitable for specific needs of mechanical equipment.
Applications: for high-precision instruments, elastic components, highly conductive parts, etc.
These different materials of copper bushings are widely used in the machinery industry according to the specific working environment and requirements. Choosing the right material can significantly improve the performance and service life of mechanical equipment.
