Copper Alloys C44300 | Product Overview
Introduction To Beryllium Copper / UNS C17200 / ALLOY 25
MOKSH TUBES & FITTINGS LLP is a reliable manufacturer, exporter, importer, and stockist of high-quality Beryllium Copper products. We offer a wide range of forms, including Pipes & Tubes, Sheets & Plates, Coils, Rods, Bars, Wire, Foil, Forgings, and Custom Components tailored to industrial needs.
Beryllium Copper, also known as Copper Beryllium, is a high-performance alloy known for its remarkable combination of strength, conductivity, and corrosion resistance. This non-ferrous alloy contains 0.4% to 2% beryllium and is often used where non-sparking, non-magnetic, and high-strength materials are required. It can be heat-treated for enhanced mechanical properties and performs excellently in electrical, aerospace, marine, and oil & gas environments.
