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
