Copper alloy castings play a dual core role in the die-casting machine industry: on the one hand, as a high-performance end product directly die-cast, they are widely used in the manufacture of precision parts such as electrical connectors, heat dissipation components, and mechanical wear-resistant parts due to their excellent electrical conductivity, thermal conductivity, and wear resistance; sebaliknya, ia juga merupakan bahan utama untuk membuat acuan tuangan die sendiri (seperti teras dan penebuk). Their extremely high thermal conductivity and thermal fatigue resistance can significantly improve mold life, ensure production efficiency and casting quality, and are an important foundation for supporting the efficient and stable operation of the entire die-casting process.
