• Turned parts

Lebronze alloys Group produces special copper alloys for the machining and turning market.

The requirement for drilling and turning properties in combination with the individual application determines optimal combinations of copper, zinc, lead and other elements.

Properties of the alloys are defined to meet the machinability, productivity,  stable dimensional tolerances. For flanging, cold forming and crimping, composition is adjusted to optimize the machine performance and final results.
In comparison to steel, the tool life, chip braking properties and productivity are given due to the chemistry (elements such as lead assists in chip breaking).

Environmental rules and laws will change the future with a direct influence on the machinability of brass alloys. Therefore Lebronze alloys group works closely together with customers and partners to find industrial solutions.

This co-operation has led to a new generation of alloys named EnviB10 and EnviB1. These alloy families comply with the demands of RoHs and CPSIA whilst retaining good machining properties.



  • High precision drilling, turning, cutting, broaching for all kind of mechanical components
  • Very short chip breaking and high speed machining
