6060, 6061, and 6063 are all part of the 6000-series aluminum family, but they’re built for different tasks:
-
6060 Aluminum is the lightweight champ—super easy to extrude into tricky shapes like window frames or furniture, though it’s not very strong.
-
6061 Aluminum is the tough one, with more magnesium for strength, making it great for bike frames or boat parts; it’s still workable but not as flexible for fancy shapes.
-
6063 Aluminum is the pretty—best for smooth, shiny finishes like door trims or railings, with solid extrudability but less strength than 6061. All three fight rust well (6063 are the best), and they’re easy to weld. Pick 6060 for delicate designs, 6061 for sturdy builds, and 6063 for looks that last!
