Formula: Cu 98/Be 2
Form: Foil/Film/Sheet
Material: Copper/Beryllium Alloy
Commodity: Alloys
Copper/Beryllium Foil (Cu98/Be2), also known as CuBe2 foil, is a high-performance alloy known for its excellent strength, conductivity, and resistance to wear and fatigue. This advanced foil uniquely combines copper’s excellent electrical and thermal conductivity with beryllium’s superior strength, stiffness, and fatigue resistance, resulting in a remarkably durable material. Its uniform thickness and high-quality surface finish make it ideal for applications in electronics for high-reliability connectors, relays, and printed circuit boards, as well as in aerospace and defense components where performance under stress is critical. It is also used in specialized industrial tools and precision instrumentation. Goodfellow offers premium quality Copper/Beryllium foils and sheets that meet stringent industry standards, ensuring reliable performance and durability. The foil's ability to maintain its properties under extreme conditions makes it an ideal choice for demanding applications. Goodfellow's commitment to quality ensures that the CuBe2 foils sourced are suitable for a wide range of engineering and industrial projects.
