As an important supporting facility for new energy vehicles, charging piles’ performance and reliability directly affect the use experience and promotion of new energy vehicles. In the design and manufacturing of charging piles, the molded case circuit breaker（MCCB) is a key electrical component. It is responsible for cutting off the current when the circuit is overloaded or short-circuited and protecting the safety of the circuit and equipment. The choice of contact material is particularly critical because it directly affects the charging efficiency and safety. Powder metallurgy technology plays an important role in the manufacturing of contact materials because of its unique advantages.

    Powder metallurgy technology is an advanced manufacturing process that creates materials with excellent properties by pressing and sintering metal powders under high temperatures and pressures. Powder metallurgy contact materials AgW50 and AgWC12C3 have been gradually introduced on the market. Due to their highly dispersed organizational structure, they show excellent performance and have become the ideal choice for contact materials of molded case circuit breakers for charging pile . These materials can not only improve the charging efficiency and safety of charging piles, but also ensure long-term stable performance in complex working environments.

    Product advantages:

    ① Excellent resistance to welding: Under high current and high temperature conditions, powder metallurgy contact materials can maintain stable contact resistance and reduce poor contact caused by welding, thereby improving charging efficiency and safety.

    ② Good electrical conductivity: Silver-based alloy has excellent electrical conductivity, ensuring high-efficiency energy transmission during the charging process.

    ③ High wear resistance: The powder metallurgy process can optimize the microstructure of the material, improve the hardness and wear resistance of the material, and extend the service life of the contact.

    ④ Stable chemical properties: In complex working environments, these materials can resist corrosion and oxidation and maintain long-term stable performance.
