Copper castings are made primarily from pure copper, which typically contains at least 99.9% copper. The high purity of the copper ensures its excellent electrical and thermal conductivity properties.

Copper is known for its exceptional electrical conductivity, making copper castings an ideal choice for electrical components and conductors. It is widely used in electrical wiring, connectors, and various electronic devices.

Copper also boasts excellent thermal conductivity, making it suitable for heat sinks, cooling systems, and applications that require efficient heat transfer. Copper is highly resistant to corrosion in various environments, especially in atmospheric conditions. It forms a natural patina over time, which further enhances its protective properties against corrosion.
