Copper Alloy
Beryllium copper is an alloy containing small amounts of beryllium, usually between 0.5% to 3%, making it one of the strongest copper alloys.
- Beryllium copper exhibits excellent resistance to corrosion, particularly in air and water, making it suitable for harsh environmental conditions.
- This alloy can be heat-treated and machined into various shapes, showing outstanding performance in the production of precision components.
- Compared to regular copper alloys, Beryllium Copper offers significantly higher strength and can withstand substantial pressure and mechanical loads.
- It maintains strong mechanical properties even at high temperatures.
- Beryllium copper is non-magnetic, making it ideal for use in explosive environments.
- It is highly resistant to wear, making it perfect for components subjected to high wear and tear.
- It can be easily welded and brazed, making it well-suited for precision machining applications.
