All of our aluminum profiles are made of 6463 alum. extrusion. Below is the advantage comparing with 6063 alum. extrusion:

For many applications, 6063 is one of the most cost-effective alloys available. This alloy’s heat tolerance, strength and smooth surface make it a popular choice for window and door-frames, tubing, and heat sinks. The 6463 alloy’s characteristics are similar to 6063. This alloy is designed to accept bright-dip anodizing to achieve a highly reflective, mirror-like finish as seen in decorative trims, light frames, shower doors and reflectors.
