Beryllium Copper Electrical Wiring and Connectors
It has a variety of uses, the most common of which are electrical wiring and connectors. Beryllium copper is prized for its combination of strength, flexibility, and corrosion resistance. It is also non-magnetic, making it ideal for use in electronics.
Beryllium Copper Connectors for Telecommunications
Beryllium Copper is a metal that has been around for centuries, but it’s only recently become popular in the telecommunications industry. It was first used to make telephone networks more resilient and long-lasting against hurricanes or earthquakes. Beryllium Copper connectors are being used in many different types of telecommunication equipment because they offer an unmatched combination of performance, reliability, and durability. This material is so advanced that it can be found on satellites orbiting Earth!
Electrolytic tough pitch copper is used for wires and this grade of copper has a minimum copper content of 99.9 per cent with around 0.04 per cent of oxygen in the form of an oxide. This level of purity is essential as the introduction of some alloying elements or impurities can greatly reduce conductivity.
High purity copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color
