1. Properties
1. Wide technique range and good covering ability. The throwing power can increase by 30~60%, the current efficiency is up to 22~24%, non-corrosion at the low current area.
2. HV hardness increases by 10~30%, the period of neutral salt-spraying test increases 1~2 times.
3. Low content of chromic acid, it is 40% of routine plating solution, lower the content of chromic acid in waste water, easy to be treated, high economic efficiency.
4. The technique is stable, easy to maintain.
