Aluminum is an easy material to work with, it’s easy to cut, easy to stamp, so it’s a good choice for many sheet metal stamping products.  But since Aluminum is so soft, it’s very easy to get marked up or scratched during the constructing process, by the time we finishing cutting and stamping the parts, it’s probably being in a rough shape.

In hence most of our client ask to give the part a brushed (also called hair-lined surface treatment) especially when the parts are used as an outer case in computer case or housewares or auto parts. 

Followed is a good example, this part is used for automotive.

The hair lined treatment do upgrade the stamping part from it’s looking!
