Beryllium Copper

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.
