Manufacturing process

  • Powder metallurgy
  • Sintering

Ag WC C 79.75-20-0.25

Forms available

These electrical contacts are produced by die compacting ; a great variety of shapes is therefore possible and could be delivered with or without a sublayer (to be determined with the customer).

The most common forms are as follows :

M.C.B Contact

Industrial cicuit - breaker moving contact

A.C.B.

Typical forms for the solderable face :

Direct sintering

Brazing alloys :

  • LAg 15 P

Applications

Switchgears

  • Thermostats
  • MCB
  • Moving contact for circuit-breakers between 100 and 800 A
  • Moving contact for ACB between 1 000 and 10 000 A
  • Arcing contact for large size contactors

Uses

  • Domestic appliances
  • Distribution of electrical energy
  • Railways
  • Aircraft industry

Advantages

  • low and reliable contact resistance
  • low welding tendency

Others conditions

We manufacture according to our customers' specifications. Our technicians are readily available to discuss contact forms, dimensions and brazing requirements.
