FINGERSTOCK GASKETS Application Due to their outstanding material and electrical characteristics, beryllium copper finger of different shapes and dimension are used in the following industries: Broadcasting, telecommunications industrial control, measuring and instrumentation, aerospace technology, nuclear physics and data processing. Contact fingers and rings made of beryllium copper are used at all ratio and microwave frequencies, for instance as contacts to valves and tuning components as well as for shielding. Material Properties The beryllium copper (CuBe2) used for our products is a quality tested quench hardening spring material. It is noteworthy for its yield point, tensile strength and elasticity, good electrical conductivity, high fatigue strength as well as its resistance to abrasion and corrosion. The good thermal conductivity coupled with hardness eliminates sparking. The raw material is non-magnetic and has an excellent temperature performance.

The space needed is minimal and assembly is extremely simple as the under side of the fingers is provided with two sided adhesive strip. Extensive soldering, riveting or bolting is therefore not necessary. The measured attenuation values are excellent. Magnetic field: at 14 khz more than 46 db. Plane waves: at 10 GHz approx. 108 db. Slippy fingers are a further development of the curved fingers, where the free part of the finger is retained within a channel and is therefore protected against damage. As compression increases, the fingers will slide further into the channel.
