In our high-tech world, metal powder becomes more and more important due to its physical properties and numerous potential applications. NMD can draw on 25 years of experience in powder metallurgy and supplies industrial companies and research laboratories around the world with metal powders such as Aluminium powder, Magnesium powder, Silicone powder, Copper powder or Tin powder. The quantities delivered vary between a few kilograms up to several tons.
NMD offers neutral advice and is supplier for almost every metal powder.
Through our extensive network, we have worldwide access to almost all metal powders and manufacturing processes. Because NMD is not bound to a specific plant, our customers can always be served from the plant that is optimal for their use. This is a further advantage of NMD: This independence guarantees neutral and optimal advice. When NMD’s metal powder specialists have found the optimal metal powder for your use, NMD delivers the material both in small quantities for research as well as in large quantities for industrial use.
Metal powder production process and physical characteristics
In everyday practice of application technology and advising customers about the best powder for a specific use, extensive knowledge and the relevant production processes are required. What is decisive for success or failure is the right choice of production process for metal powder and, thus, the grain structure, the surface, the reactivity, the compactability etc. Each powder grain has the properties of the original metal, but also the advantages of powder in terms of surface, flowability, combustibility, mixability with other powders, compactability, sinterability etc. This makes modern powder metallurgy possible in the first place.
“NMD is part of a global network in the metal powder industry. As experts with decades of experience, we know exactly what matters.“
The most important production process for metal powder in overview:
• Atomisation of molten metal with gas, fluids or in the electric arc
• Vaporisation of the metal, followed by condensation
• Reduction of metal compounds
• Carbonyl procedure
• Crushing (Grinding) of solid material
• Separating the powder at the cathode in an electrolytic bath
NMD supplies metal powder for areas of use such as:
- Powder metallurgy
- Selective laser sintering (Rapid Prototyping)
- Laser deposition welding
- Chemical processes/syntheses
- Varnish and paint industry
- Electrical industry (carbon brushes, strip conductors, magnets etc.)
- Automobile industry (gear parts, corrosion protection, friction and brake lining etc.)
- Cosmetics industry (Deodorant, UV protection etc.)
- Printing industry
- Nuclear industry
The most important powder grain structures in this are:
- Spattered, irregular
- Lamellar, flake-like
