SN/CO

Bright deposit consisting of a double layer of nickel + tin/cobalt. A further deposition with a tin/cobalt alloy is carried out besides the conventional electrolytic nickel-plating deposit.

The coating is bright with an appearance identical to that of the chrome-plating with good resistance to wear and to corrosion.

Main features:

  • Bright
  • Chromium-like appearance
  • Possibility to carry out mass deposition
  • High resistance to corrosion
  • Self-passivating in presence of oxygen
  • Resistant to alkalis and to organic acids

Compliance:

  • CE1907/2006 – 18/12/06 REACH
    • Annex XIV: list of substances subject of approval;
    • Annex XVII: hazardous preparations and articles, restrictions regarding manufacturing, introduction into the market and use of some substances;
    • 59 par.10: SVHC (substances of very high concern)
  • 2011/65/UE – ROHS 3
    • • Free of lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), phthalic acid esters (DEHP, BBP, DBP, DIBP)

Compatible with the standards:

  • ISO1456:2009
  • ASTM B456

The SN/CO deposit is not compatible with any of the standards and regulations regarding water potability, contact with food products and anallergicity.
