OUR MATERIALS

Stainless Steel 316L

1.4404 (AlSl 316L)

1.4404 is a stainless austenitic chromium-nickel-molybdenum stainless steel with low carbon content. This versatile stainless steel is used in numerous industries. These include:

  • medical devices and tools
  • food and chemical industry
  • jewellery and lifestyle industries
  • automotive industry
  • aerospace

316L is one of the standard materials in almost all metallic additive manufacturing processes and can be processed and machined particularly well. In contrast to welding AM processes (e.g. LPBF), components produced by LMM have a stress-free, annealed microstructure due to the sintering process.

Titan Grade 5 Ti6Al4V

3.7164 (Ti6Al4V)

Titanium Grade V is one of the most widely used titanium alloys, with an excellent combination of strength, toughness and ductility. It is widely used in the following industries:

  • aerospace
  • medical technology and pharmacy
  • implants
  • ultrasound technology
  • energy technology

The alloy is age-hardenable. Due to the sintering process in combination with our binder system, a slight carbide formation cannot be completely excluded at present.

Properties at a glance

  • weldability
  • very good resistance to numerous corrosive media
  • high resistance
  • low density
  • high fatigue strength
