Beryllium Copper is a copper alloy with the optimum combination of mechanical and physical properties such as tensile strength, fatigue strength, performance under elevated temperatures, electrical conductivity, bending formability and corrosion resistance. Beryllium Copper is widely used as contact springs in various applications like connectors, switches, relays, etc. NGK offers a variety of Beryllium Copper alloys in several tempers to cover different applications. Our Beryllium Copper products are available in strip, plate, rod and wire forms. Age hardenable material can be formed into complicated shapes and precipitation hardened afterwards. Among Mill-hardened material, which dose not require heat-treatment after stamping or forming, "Type-B" and "Type-S" have especially well-balanced performance in strength and formability.

Copper and Copper Alloys form an important group of metals with many excellent properties. They have very good electrical and thermal conductivities, offering twice the conductivity of Aluminium and thirty times the conductivity of Stainless Steel. Copper Alloys have high ductility and are easy to fabricate, with ease of brazing and solderability. This group has many advantageous characteristics and include alloys of exceptional strength notably Copper Beryllium Alloys and corrosion resistance as well as antimicrobial properties.
Beryllium Copper Strip
The use of strip metals for connector springs, terminals, contacts, and switches is well accepted in the interconnection industry. This is particularly true for copper alloys, because of their desirable combination of conductivity, strength, and formability. The connector designer will approach each new assignment with information on a connectors desired mechanical characteristics, operating environment and life expectancy.
Our library of Tech Briefs offers in-depth information covering a range of topics related to our alloy products , including formability of strip products, soldering and surface coating recommendations and more. If you cannot find the information you need or would like to request additional technical product details, please feel free to Contact Us for more information. The formability of copper strip is dependent upon a number of variables including alloy, temper, bending direction, strip thickness, width, and method of forming.
