Machining of copper alloys – Conductivity, accuracy, cleanliness

An expertise for copper, brass and high performance alloys
Palumbo Industries machines precision components from profiles out of copper alloys — copper, brass and specific alloys —, designed for applications where electrical conductivity, mechanical reliability and particle cleanliness are essential.
We have experience in machining the following grades : Cu, C11000 H04, TeCu, C14500, on transfer machines and automated machining centers, ensuring stable geometries, clean cuts without burrs, and a constant quality over large series.
Our offer includes specific coatings to enhance electrical performances such as :
- silver plating (improvement of conductivity)
- des finitions contrôlées pour réduire l’oxydation et assurer la stabilité dans le temps
Applications of machining of copper alloys

A strict quality control of copper alloy machining
Electrical, dimensional and visual inspections, for a comprehensive reliability
Components out of copper and brass require specific inspections in order to check their electrical performance.
At Palumbo Industries, every component undergoes dedicated controls :
- periodic dimensional measurements on the production line
- automatic camera inspection
- eddy currant inspection to control defects of the material
- reinforced visual inspections to ensure a perfect cleanliness
- 100 % automated final inspection
These controls guarantee the electrical reliability, the geometrical compliance and the traceability.
