Materials used in high-precision machining

The different materials used in the production of our parts
Joseph Martin, specialist in screw-cutting since 1946 in the Arve valley in Haute-Savoie (74) in France. Our equipment and know-how allow us to manufacture parts in various material such as:

 Technical plastics

  • PEEK: natural Peek, PEEK with carbon fibre, graphite & Teflon
  • TEFLON (PTFE)
  • PVDF (polyvinylidene fluoride)
  • POM (polyoxymethylene): POM C and POM H
  • Ertalon (PA)
  • Filled or natural PEEK (450G, 450FC30)
  • Ertacetal
  •  Delrin
  • PTFE (Teflon)
  • PA66, PA66GF30 (Polyamide)
  • Amodel
  • PPS FV Ryton BR 42B, Ryton BR111

Stainless steels

  • Ferritic
  • Magnetic
  • Martensitic
  • Austenitic

Steels

  • Nickel alloy
  • Pre-treated steel (ETG25, ETG88, ETG100, Usimax D950, 42CD4, 25CD4)
  • Free cutting steel (S300, S300Pb, 11SMn30, 11SMn37, 9SMn28, 12L15, 1215, C10C)
  • Alloy steel (44SMn28, 35NCD16, 100Cr6)
  • High carbon steel
  • Low carbon steel
  • Silicon steel
  • Refractory

copper allow turning

Copper alloys

  • Brass with lead (CW608N / CuZn38Pb2, CW614 / CuZn39Pb3, CW603N / CuZn36Pb,…)
  • Brass without lead (CuZn40 / CW509L, Ecobrass CuZn21Si3P)

We have developed processes for the Connector industry that enable lead-free brass to be manufactured improving productivity.

  • Bronze (BZ4, PS2, Cuproberyllium)
  • Copper C1100 (CW004A / Cu-ETP)

Aluminum

  • Range 2000
  • Range 6000
  • Range 7000
  • ALECO 62 Sn …

Other materials:

  • Carbon steel
  • Silver
  • Pure iron
    • Silicon iron (FeSi3P)
  • Titanium
