HardGrey®

Galvanic treatments


Main board

SURFACE TREATMENT ON ALUMINUM AND ITS ALLOYS.
MAXIMUM PROTECTION AGAINST CORROSION.

  • Increased surface hardness
  • Good corrosion resistance
  • MIL A 8625F and UNI 7796 compliant
  • Ceramic treatment
  • Low friction coefficient
  • Low alteration of surface roughness

Hibrid-hard anodizing is a process that guarantees good hardness and anti-wear performance with no chromatic or roughness changes, typical of a standard hard anodizing.

Other informations

CORROSION RESISTANCE

The oxide layer created is well resistant to all solutions whITH pH between 4 and 9.5. The resistance in neutral salt spray test exceeds 500-550 hours.

THICKNESS

HardGrey is formed with great regularity following the course of the surface. The layer behaves as a conversion for its 50% of thickness and half as a growing. The standard thickness is 20 microns.

COEFFICIENT OF FRICTION

HardGrey has a low friction coefficient and a low alteration of the initial roughness of the piece.

APPLICATIONS

Nautical, marine, automotive, motorcycle, textile, mechanical, electrical, aeronautical, agricultural machinery, packaging machines.
