Chrome metal electrolytic (ECR)

Chrome metal electrolytic (ECR)

GOST 5905-2004

Appearance: metal of iron-grey colour in flakes up to 0,5 mm thick.

    Used for:

  • Special alloys production (by melting of heat-resisting steels) as an alloying element;
  • Diffusion coating, in production of sputtering targets for chrome plating in electronics and in electrotechnics;
  • Powder metallurgy;
  • Protective-decorative purposes (surface treatment of equipment, automobile and bicycle parts etc.);
  • Improving of reflection power (in mirror, spotlight and deflector production);
  • Increasing of wear resistance (of metals, resin, leather, glass, and plastics);
  • Reconstructing of lost dimensions of abraded surfaces, etc.
