Beryllium copper
Excellent fatigue characteristics for repetitive motions, suitable for components requiring long life!
"Beryllium copper" is a copper alloy that contains a small amount of beryllium added to copper. While maintaining the excellent electrical and thermal conductivity of copper, it possesses high strength comparable to special steel, excellent spring properties, corrosion resistance, and fatigue characteristics. It is widely used as spring materials and sliding components in fields that require high reliability, such as electronic components, automobiles, and communication infrastructure. Our company is capable of processing beryllium copper. For many years since our establishment, we have been enhancing our expertise in the processing of copper and copper alloys. You can trust us with small lots, custom matching, short delivery times, large-scale processing, and ultra-precision processing. [Main Features] ■ High strength and spring properties: Achieves high tensile strength comparable to special steel through precipitation hardening treatment, making it excellent as a spring material. ■ High conductivity: Depending on the type and condition of the alloy, it has high conductivity and is suitable for components requiring high current density. ■ Excellent fatigue characteristics: It excels in fatigue characteristics against repeated operations, making it suitable for components that require long service life. *For more details, please download the PDF or feel free to contact us.
