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.
