Application
Components for Aerospace: Due to their high strength-to-weight ratio and resistance to stress relaxation, these alloys are used in aerospace components such as bearings, springs, connectors, and undercarriage parts.
Defense Applications: Their reliability under extreme conditions makes them suitable for components in defense equipment, including guidance systems, satellite and radar systems, and avionic instruments.
Automotive Electronics: Copper-beryllium alloys are used in automotive electronic connectors, sensors, and switches due to their excellent electrical conductivity and resistance to corrosion.
Safety Systems: Components in safety systems, like airbag deployment mechanisms and seatbelt systems, benefit from the high strength and reliability of these materials.
Connectors and Relays: The high conductivity and resistance to oxidation and corrosion make these alloys ideal for connectors, relays, and switches in electronic devices.
Precision Components for Telecommunications: Components that require precision and reliability, such as connectors and spring contacts in mobile phones and other communication devices, often use copper-beryllium alloys.
Tools and Dies: Tools and dies made from copper-beryllium alloys are used in environments where sparking cannot be tolerated, such as in oil and gas extraction, due to the non-sparking properties of these alloys.
Bearings and Bushings: These components benefit from the alloy’s durability and resistance to wear and galling, ensuring longevity and reliability in machinery and engines.
Springs and Membranes: The formability and strength of copper-beryllium alloys allow them to be used in springs, membranes, and other flexible components in consumer electronics, ensuring long-term performance and reliability.
Non-Magnetic Instruments: For environments requiring non-magnetic tools, such as MRI rooms, copper-beryllium alloys provide strength without interfering with magnetic fields.
