Aluminum alloy with zinc plating + trivalent black chromate for high corrosion resistance.
Aluminum alloy with 'zinc plating + trivalent black chromate'
Features of zinc-coated aluminum alloy material with trivalent black chromate 1. Zinc coating is possible on aluminum alloys. 2. Our company uses a cyan bath zinc plating solution that generates fewer whiskers than a zincate bath. 3. It provides a beautiful black appearance with trivalent black chromate. 4. With trivalent black chromate (appearance-focused specification), it has corrosion resistance with no white rust after 96 hours of JIS salt spray testing. 5. With trivalent black chromate (corrosion resistance-focused specification), it has corrosion resistance with no white rust after 240 hours of JIS salt spray testing. 6. With trivalent chromate (white), it has corrosion resistance with no white rust after 240 hours of JIS salt spray testing. 7. All zinc plating and chromate processes comply with the RoHS directive. 8. Method: Barrel plating (rotary plating), jigs. 9. It has conductivity.
