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 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.

- 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
