Services / Turned parts in non-ferrous metals

Brass turned parts and copper and bronze parts

Fitting parts, contacts, bushings and bearing parts in brass, copper and bronze — from the bar feeder, in series of up to 10,000 pieces.

Turned parts in non-ferrous metals

Free-cutting brass is the fastest material to turn: short chips, smooth surfaces, long tool life. That makes brass ideal for turned parts in larger quantities — running from the bar feeder even without an operator.

Copper, by contrast, is soft and smears; it needs sharp tools and experience. We use aluminium bronze and gunmetal for bearing and sliding parts that must withstand wear and corrosion.

Design tips

  • Choose free-cutting brass unless something speaks against it: CuZn39Pb3 is considerably cheaper to turn in series than other copper alloys.
  • Drinking water: parts in contact with drinking water are subject to special requirements on lead content — please state this in your enquiry.
  • Make use of bar diameters: parts up to Ø 52 mm can be made from the bar feeder — the most economical route for series.
