What is a Beryllium copper?

Beryllium copper (BeCu) is an alloy of copper and beryllium, known for its high strength and excellent electrical conductivity. The addition of beryllium enhances the strength of copper, making it approximately four times stronger, while maintaining its electrical and thermal conductivity. Beryllium copper is highly resistant to wear and corrosion, making it suitable for use in harsh environments. It also offers good workability and can be heat-treated to further improve its strength. Due to these properties, beryllium copper is widely used in applications requiring high-strength and precision parts, such as electrical contacts, springs, connectors, and precision machinery components. It is commonly found in industries like aerospace, electronics, and automotive. However, due to the toxic nature of beryllium, caution must be taken when handling the alloy.

Application of Beryllium copper

１．Electrical Contacts: Beryllium copper is used in electrical contacts for high-performance applications, where both high strength and good electrical conductivity are essential.
２．Connectors: Due to its excellent fatigue resistance and electrical properties, beryllium copper is commonly used for connectors in aerospace and automotive industries.
３．Precision Springs: Beryllium copper is used to manufacture springs that need to withstand high stress and maintain precision, such as in electronics and automotive components.
４．CNC Machine Parts: High-precision, strong parts for machines that require durability and conductivity, such as tools and gears, are made from beryllium copper.
５．Relay Components: Beryllium copper is widely used for making components in electrical relays that require both strength and conductivity.
