Innovative Metals

Siliconised graphite is a multipurpose material with unique properties as follows :

  • Erosion and corrosion resistance to the most aggressive environments (including hydrogen acid)
  • More precisely the material is resistant to concentrated and weak acids (including hydrofluoric acid) and alkalis, methyl chloride, acetic anhydride, and ethyl acetate at temperatures up to boiling, caprolactam melt and molten metals.
  • High temperature resistance (up to 500ºС)
  • Resistance to repeated thermal impacts
  • Sliding speed of up to 200 m/s
  • Loads of up to 15 MPa in critical friction assemblies
  • At start-up and hitch stages, able to work with dry friction for up to 40 seconds
  • Service life of friction assemblies of 50,000 hours.

  • The main applications are :
  • In combined heat and power station it is used for circulating pumps mechanical seals
  • In steel industry is used for friction components like O-rings, thrust bearings, plain bearings in pump reactors and separators.
  • And also as protective devices for immersion thermocouples used to measure temperatures of molten iron , copper , zinc and other metals
  • Plus locking and casting supplies for steel furnaces and ladles for pouring molten metal.

aluminium_foam

Metal foam has become a very popular term which is nowadays used for almost any kind of metallic material which contains void. It is a cellular structure made up of a solid metal containing a large volume fraction of gas-filled pores.

All metallic foams have enormous applications in Energy absorption, filtration, sound suppression, magnetic shielding, vibration damping, stiff lightweight panels, thermal insulation barriers, storage media, fuel cells, and heat exchangers.

We are able to propose 5 different metallic foam (copper,nickel, stainless steel , carbon ) and this Aluminium foam is an example specific to high level of resistivity.
