We extrude profiles in a wide range of alloys. With our state-of-art billet casting facility, we can even tailor make adjusted alloy for our customer. A simple example: for brite-dip material we tailor make our billet with increased copper content to improve glossiness, while with reduced Iron content to avoid die lines.
In Kam Kiu, we strive to serve our customer as a "one-stop" aluminum solution.

Following is the list of the major extrusion alloys we produce:
