Stainless steel

The most commonly used metal in photo chemical-etching is stainless steel. Its favourable material properties — combined with the large number of related alloys — make stainless steel the metal of choice for many applications in a wide range of industries.

Typical examples of stainless steels etched by micrometal include:
• 1.4310: (AISI 301)
• 1.4404: (AISI 316L)
• 1.4301: (AISI 304)
• In addition to the well-known austenitic metals a variety of ferritic, martensitic (1.4028 Mo/7C27Mo2) or duplex steels, Invar, Alloy 42,etc...

micrometal’s “Etching Group” etches a variety of other metals with a precision that is unparalleled anywhere in the world. The thickness of the processed sheets and foils ranges from 0.003 mm to 1,5 mm. Just let us know the requirements of your component and we will assist you with material selection.


Photo-chemische Ätztechnik

Wide range of etchable metals

Thanks to our innovative manufacturing processes, a variety of etchable metals and alloys can be photo-chemically etched, such as titanium, molybdenum, aluminum, gold, silver, and copper and its alloys.

  •  Nickel and cobalt materials (e.g. Ni, Mu-metal, HyMu 80, Alloy 52, Elgiloy (Phynox), Kovar, Hastelloys, Inconels, Haynes alloys, Nicrofer)
  •  Copper and copper alloys (e.g. copper beryllium, bronzes, brass, nickel silver)
  • Amorphous or nanocrystalline materials (e.g. Vitrovac 6025, Vitroperm 500)


If etching an alternative (composite) metal or metal-plastic laminate is of interest to you, please let us know. We will be happy to check the corresponding etching chemistries and processability of our etching technology for you.
