MATERIALS

• CuCrZr

  CuCrZr is the main material, wherever better mechanical properties compared to standard copper is needed while still giving very good electrical/thermal conductivity. All this in combination with good elongation values.

  We are able to process CuCrZr in several ways:
  + casting
  + cold forming/bending
  + CNC machining
  + welding
  + soldering

  That way we can offer you both casted, as well as cold formed/bended, or CNC machined solutions; all according your needs to the best cost.

• CuCoBe

  CuCoBe is mainly used wherever the usual copper alloys would not have sufficient strength/hardness, e.g. heavily loaded gun arms for reistancewleding.

  As one of the few suppliers in europe we can cold bend also CuCOBe from rod material up to 60 mm diameter.

  We are able to process CuCoBe in several ways:
  + casting
  + cold forming
  + CNC machining
  + welding (partially)
  + soldering

• CuNiCrSi

  CuNiCrSi is the alternative material to CuCoBe without Be-content.

  Parts out of CuNiCrSi have comparable electrical/thermal properties in combination with almost the same hardness/tensile strength as CuCoBe.

  Also here the main application is resistance welding.

• CuBe2

  If copper parts have to fullfill highest demands, CuBe2 is the first material choice when it comes to hardness, wear resistance and strength.

  With tensile strength of up to 1.200 N/mm² and hardness of more than 400 HV we reach applications that usually copper based materials cannot deal with.

  As the material contains still more than 97 % copper a sufficient thermal and electrical conductivity can still be achieved. Parts are mainly used for butt welding components, dies and electrode gun arms with highest demands (metal forming and welding in one step).

• PURE COPPER

  If mechanical demands are not the first priority, but best electrical or thermal conductivity copper is thefirst choice of all technical metalls.

  Outstanding elongation and formability in combination with our special know-how in the machining of soft copper materials enable us to fullfill customer demands.

  Other than casting we process pure copper in all other form giving processes. The biggest parts are around 200 kg/pcs.

• BRASS

  Brass is the cost competetive alternative and the material giving a good property combination of other copper based alloys.

  We are able to process CuCrZr in several ways:
  + casting
  + bending
  + CNC machining
  + welding
  + soldering

• ALUMINIUM

  As per customer demand we also machine aluminium parts of plate/rod.

  Mainly very big gun arms are made out of aluminium, giving the obvious advantage in weight vs. copper.In relation to it`s density some aluminium alloys show even better specific electrical conductivity, in absolute figures copper gives better values of course.

  With our CNC milling machines (1.400 x 800 x 1.000) and lathes with turning length of up to 1.500 mm we can machine all aluminium components needed.
