Trivalent Chromium Passivation for Aluminium Plate

1/

Using trivalent chromium filming process to replace hexavalent chromium process. The oxide film on the metal surface has the characteristics of low contact impedance, corrosion resistance (MIL-DTL-5541F regulation passed, neutral salt mist test 36hrs), high temperature (100℃)resistance. This material can be applied to cars, aerospace, mechanical assemble, photoelectric, semiconductor, facilities for food and medical devices. The sewage generated by the process can be proper treated in circulating water system to prevent from pollution. more
