Material

DIN 17223 C-Wire WERKSTOFF NO. 1.200
Working temperature between -30 ºC and +120 ºC

Galvanization

The galvanised range is manufactured of electro-galvanised music wire. Electro-galvanisation means that the spring gets a blank and more corrosion resistant surface.

Calculation of spring force

Fn for stainless steel spring steel is approx. 0.88 x Fn for music wire.

Calculation of spring force at a given length is travel s * R

If compression springs with a very high spring constant/carrying capacity are required, coloured die springs are recommended.

Winding direction

Normally right-handed

Misc.

If the springs are compressed to Ln, the spring will set itself. It will then not return to its original length, L0.

Always dimension a spring so that it delivers the desired travel and force with as little exertion as possible. This prolongs the service life of the spring. Applying maximum load to the spring will shorten its service life and cause it to become permanently distorted.
