With metal it's more about the balance of dark and lights, which is completely different from other materials, than about texture. (Also, with colored metals, the color of the highlights is very important.)
The texture part is relatively easy, in this case I used a brush textured to make random scratchy lines, sometimes used for grass, and then used Unsharp Mask to pop it out.
