What is the recommended hard anodising process for 7075 and 2015 alloys?
- Banbury Oxfordshire, England
Hard anodising of different alloys are carried out in 15 to 20% sulphuric acid solution at 0 to -5 deg. centigrade. The voltage to be increased slowly and the final voltage and time depends on the desired thickness.

Eg. 50 to 75 micron thick can be obtained at about 30 to 33V final voltage. It would take about 2 to 2 1/2 hr time for obtaining this thickness.
