Bright dipping extruded aluminum part
Bright dipping extruded aluminum part
(OP)
I am bright dipping an extruded aluminum part ( size about 4 inches X 4 inches )
The reason for bright dipping is to get a high appearance shine.
MY QUESTION IS: Will the bright dip process provide a coating that will give me a rust prevention characteristic? How long will this last to outside elements? How much better will the bright dip process be compared to just a bare aluminum extrution in regards to rusting.
Thanking all in advance.

RE: Bright dipping extruded aluminum part
Normally, this type of process is used as a pretreatment of the aluminum. It should be followed by a coating process, which could include primer and coating. A good process to consider is clear coat anodizing or hardcoat anodizing. Clear coat is just that. The aluminum maintains it's original color, unless its dyed. The hardcoat is a tough coating. Anodize is chemically known as aluminum oxide. Aluminum oxide is hard Rc 60's. Great corrosion barrier. Used a lot in military application and cookwear.
