DMLS

Aluminum AlSi10Mg - Direct Metal Laser Sintering - DMLS material
AlSi10Mg built on our SLM 280HL

Aluminium - AlSi10Mg
Aluminium has a density of 2.7 g/cm3 and has a melting point of 660 centigrade. It can be processed relatively easily by casting, machining and pressing. Due to its low strength it is used to produce alloys from silicon, magnesium, copper, manganese and zinc. Aluminium oxide (Al2O3) can also be found extensively as a ceramic.

 

Material Properties

  • Low density
  • Good alloying properties
  • Good processability (casting and pressing etc.)
  • Good electrical conductivity
Areas of Applications

  • Automotive
  • Aerospace
  • Consumer goods

Nickel-base alloys - Inconel 625 & 718
Developed in the early 1960's, IN718 is still considered the material of choice for the majority of aircraft engine components with service temperatures below 1200°F (650°C). Inconel 718 is a precipitation-hardenable nickel-chromium alloy containing significant amounts of iron, niobium, and molybdenum along with lesser amounts of aluminum and titanium. It combines corrosion resistance and high strength with outstanding weldability including resistance to postweld cracking. The alloy has excellent creep-rupture strength at temperatures to 1300°F (700°C).

Material Properties

  • Corrosion resistance
  • Excellent mechanical strength up to 700°C
  • Outstanding Weldability
Areas of Applications

  • Aerospace
  • Energy Technology
  • Tool & Die

Cobalt-Chrome - CoCr
Cobalt-Chrome alloys are standard alloys in the medical and dental fields. Due to the high hardness, Cobalt-Chrome alloys are used to produce dental prostheses. This is also influenced by the biocompatibility of the alloy. Being a tough material, Cobalt-Chrome alloy is usually cast and not machined. Other uses for Cobalt-Chrome are prosthesis and knee or and hip joint implants.

 

 

Material Properties

  • Good toughness
  • Corrosion resistance
  • High strength
  • Bio-compatibility
Areas of Applications

  • Medical technology
  • Dental technology
  • High temperature
