Does salt corrode aluminum?

Will salt adversely affect an Aluminum casting? We manufacture sifters that use a cast Aluminum housing. The product contains 30% salt. Will this corrode the Aluminum?

Thanks,

We know that aluminum is NOT resistant to seawater; pitting occurs. I do not know if dry salt will react with the aluminum over time...but air moisture would be a factor there.

White corrosion will break out like a rash. An Inexpensive way to protect this would be to use masking compound used in electroplating to be applied all over your sieve.
