Optimized Local Surface Treatment, copper coating on aluminium

Optimized Local Surface Treatment

OLST technology (Optimized Local Surface Treatment) is a plating of copper on aluminium. The two metals are inseparably welded together in a special process based on dynamic gaz cold spray associated to a fast moving robot.

 This process combines the advantages of light metals - low weight, easy workability, etc. - with the advantages of copper, such as corrosion resistance, the property of being soldered, special features for electrical purposes.

 

Main characteristics of the OLST technology:

  • Good adherence
  • Clean and precise process without any conductor deterioration
  • Minimal oxidization
  • High thermal and electrical conductivity
  • Stable phase and basic material composition
  • High density, low porosity, dense coating
  • Ability to combine materials normally incompatible (electrolytic action)
  • Wide range of coating materials

 

Key applications:

  • Low inductive Laminated Busbars
  • Power Connection Rails
  • Heat sink, CTE mismatch, better solderability

 

Power Connection Rails: Universal & innovative aluminium profiles

  • An economical alternative to your copper busbars up to 1600A
  • Copper-plated contact surface for an excellent connection quality
  • Weight savings: up to 58% compared to copper bars
  • Compatible with a large range of holders
  • Easy and quick assembly / wiring
  • No need to drill holes, no limited number of connections
  • Easy to add connections after installation
