When choosing copper forging materials for construction machinery, the following characteristics need to be considered:
- Strength and hardness: parts of construction machinery usually need to withstand large loads and shocks, so copper forging materials should have sufficient strength and hardness to ensure that they will not be deformed or broken during the working process.
- Plasticity: Copper forging materials should have good plasticity in order to be processed into complex shaped parts by forging and forming processes.
- Corrosion resistance: Construction machinery often works in harsh environments, such as moisture, acid and alkali liquids, etc., so copper forging materials should have good corrosion resistance and can resist the influence of oxidation, solution erosion and other factors.
- Electrical and thermal conductivity: due to the frequent need to transmit current and heat in construction machinery, copper forging materials should have good electrical and thermal conductivity to ensure the normal operation of electrical equipment and heat dissipation system.
- Weldability: In order to facilitate the welding process in the manufacturing and maintenance process, copper forging materials should have good weldability to ensure the quality and reliability of welding connections.
Commonly used construction machinery copper forging materials include:
- Copper aluminum alloy: with high strength, hardness and wear resistance, suitable for parts requiring large loads and impact loads.
- High-strength brass: with high strength and plasticity, it is suitable for parts requiring high comprehensive performance.
- Silicon bronze: has excellent corrosion resistance and wear resistance, suitable for parts with harsh working environment.
- Tin bronze: has good wear resistance and corrosion resistance, suitable for parts requiring higher friction and wear properties.
When selecting copper forging materials, it is necessary to comprehensively consider the use environment, working conditions and design requirements of construction machinery to achieve the best performance and life.
