  • B152

Corrosion Resistance

The material also offers excellent corrosion resistance when exposed to atmospheric conditions or saltwater environments, making it suitable for marine applications as well.

Heat Treatment

When manufacturing parts with copper C14530 it is important to consider the heat treatment process, which can significantly affect the mechanical properties of the material. Heating at temperatures between 600°C–800°C (1112°F–1472°F) can improve strength, while heating at temperatures above 900°C (1652°F) will reduce strength.


It is recommended that machining be done with standard cutting tools, as special tools are not necessary due to the relatively soft nature of copper alloys compared to steel alloys.


Due to its low melting point (~1000 °C / 1832 °F), welding with copper alloys can be tricky if you don’t have experience with them. However, there are a few methods that work well, including gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW). It is important that you practice proper safety precautions when welding with these materials as they produce hazardous fumes which must be properly ventilated or filtered out using protective equipment such as respirators or face shields.


Copper C14530 offers a wide range of advantages over other metals, including strength, durability, corrosion resistance, heat resistance up to 400 °C (752 °F), a low thermal expansion rate of 6 x 10-6/°C, the good electrical conductivity of 17%, non-magnetic behaviour, and ease in machining using standard cutting tools. Making sure you understand how this material behaves under different conditions will ensure your parts perform optimally in any environment they may encounter while still providing cost savings over other more expensive metals like titanium or stainless steel. With proper knowledge about its composition, mechanical properties, physical characteristics, uses corrosion resistance, heat treatment, machining, and welding processes, you can confidently incorporate Copper c14530 into your projects.
