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

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.
