Tip welding

A large range of electrical contacts based on the alloys of silver for switchgear and controlgear used in the range 16amps - 100amps and where high bond quality is essential.
The diversity and flexibility of production methods used by Metalor Technologies is designed to meet most requirements in contact combinations and batch sizes from a few thousand to many millions of parts.

Application

  • Switchgear and Control Gear
  • Transport
  • Protection :circuit breakers
  • Transmission :relays
  • Industrial controls :contactors
