SurTec 650 chromitAL® is a trivalent process which is RoHS and WEEE compliant. It is widely used in the electronics industry due to low surface resistance, and in the aerospace industry due to high corrosion protection on unlacquered surfaces. It combines increased corrosion resistance while still preserving electrical conductivity.

SurTec 650 chromitAL® is suitable for alloyed and casted aluminium, plus pre-treatment before lacquering, powder coating and gluing. It is easy to handle and produces a visible layer of coating which is iridescent, and faintly blue to tan in colour.

It offers:

  • Low contact resistance
  • Corrosion resistance
  • A good paint base that allows bonding
  • Electrical conductivity
  • Visibility
  • Heat resistance up to 100 °C (212 °F) with minimal loss in corrosion resistance.
  • Cost effective
