Performance of Cu-OFE Copper

Physical properties

1. Electricity conductivity: The conductivity value is about 100% IACS, which is much higher than other types of copper alloys, even higher than annealed copper.

2. Corrosion resistance: The absence of oxygen in the alloy eliminates the formation of copper oxide, a common cause of corrosion.

3. Thermal conductivity: Thermal conductivity is about 401 W/mK, which is higher than other types of copper alloys.

4. Density: 8.9 g/cm3

5. Melting point: 1083°C

Manufacturing performance

1. Compactibility: It can be easily formed into different shapes without cracking or breaking.

2. Machinability: It can be easily cut, drilled and machined using conventional machine tools.

3. Weldability: It can be easily welded using various methods such as TIG, MIG and spot welding.

4. Solderability: It can be easily welded with low melting point alloys

5. Anodizing: Cu-OFE cannot be anodized
