Common phosphating for both CRC and aluminum components?

Is there any common spray phosphating which works on both crc and aluminum components?

Yes, Manish. These "dual metal" phosphatizing solutions are readily available from most of the suppliers of pretreatment chemicals. Phosphatizing is not the ultimate pretreatment for aluminum, but it's serviceable.

Dear Manish Dhyani,

You can use a common treatment solution for phosphating of steel and aluminium components. These baths usually have fluoride salts as one of the constituents, to complex the aluminium.
