Overview of Copper Casting Services
Copper casting represents one of the most critical manufacturing processes for producing high-performance electrical and thermal components across diverse industries. Our comprehensive Copper casting services encompass traditional sand casting, investment casting, centrifugal casting, and continuous casting methods to deliver superior quality Copper components. The inherent properties of Copper, including excellent electrical conductivity, thermal conductivity, and corrosion resistance, make it an indispensable material for electrical equipment, heat exchangers, marine applications, and architectural components. Our ISO 9001:2015 certified Copper casting foundry utilizes advanced metallurgical techniques and quality control systems to ensure consistent material properties and dimensional accuracy in every casting produced.
Copper casting foundry operations require specialized expertise in handling Copper alloys and maintaining precise temperature control throughout the casting process. Our foundry is equipped with modern induction furnaces, automated pouring systems, and computerized process control to achieve optimal casting quality. The foundry specializes in producing castings from various Copper grades including C101, C102, C110, C11000, and specialty electrical grade Copper alloys. Advanced sand preparation systems, core making facilities, and heat treatment capabilities enable us to produce intricate geometries with tight tolerances ranging from ±0.5mm to ±2mm depending on casting size and complexity.
High conductivity Copper casting demands exceptional purity levels and controlled atmospheric conditions to preserve the electrical properties of the base material. Our specialized high conductivity Copper casting processes utilize oxygen-free Copper grades such as C10100, C10200, and C10300 to achieve electrical conductivity values exceeding 100% IACS (International Annealed Copper Standard). The casting process incorporates protective atmospheres, controlled cooling rates, and post-casting heat treatment to optimize grain structure and eliminate porosity that could compromise electrical performance. These high-grade castings find applications in electrical switchgear, transformers, motor components, and high-frequency electronic devices.
Copper electrical grade castings represent the pinnacle of precision foundry work, requiring adherence to stringent electrical industry standards and specifications. Our electrical grade Copper castings meet ASTM B505, BS 6017, and DIN 17670 standards for electrical applications. The manufacturing process incorporates electromagnetic stirring, vacuum degassing, and controlled solidification to achieve uniform microstructure and eliminate defects that could affect electrical conductivity. Surface finish requirements for electrical grade castings range from Ra 1.6 to Ra 6.3 micrometers, achieved through precision machining and specialized surface treatment processes.
