Corrosion Resistance

This alloy offers excellent corrosion resistance because it contains low levels of sulfur and phosphorus, which help reduce the chances of galvanic corrosion. Additionally, it also provides protection from acid solutions thanks to the presence of tin, which helps prevent pitting from occurring.

Heat Resistance

The presence of nickel helps increase the heat resistance qualities of this material significantly, allowing it to withstand temperatures up to 600 °C without experiencing any major damage or degradation.

Heat Treatment

This alloy can be hardened using various heat treatments such as annealing, cold working, hot working, solution annealing, stress relieving, tempering, etc.

Machining

Copper C113 can be machined using conventional tools such as drills, taps, saws, grinders, etc.

Welding

This alloy can be welded using TIG welding techniques but should not be welded with oxyacetylene due to the high risk of cracking during the cooling process afterwards.

Conclusion
