The easiest marine-grade aluminum alloy to weld, 5052 is made into everything from boat hulls to aircraft fuel lines. You don’t need to preheat the metal or perform a test weld to create joints. Even when submerged for long periods of time, it won’t weaken in salt water. It even stays strong at cryogenic temperatures, so it’s commonly made into piping for liquid nitrogen.

Balance high strength and workability. Initially designed for aircraft frames, 2024 aluminum is turned into parts that need to be especially strong, such as couplings for servomotor shafts. It’s one of the most widely used high-strength alloys, made into fasteners, gears, and everything in between. It’s also easier to form and weld than 7075 aluminum, among the strongest aluminum alloys out there.

Bend, press, and draw 3003 aluminum into various shapes. It's easy to form and resists mild chemicals, so it's often turned into bottle caps, foil trays, and other food service products.

Make parts that are easy to keep clean. With a smoother surface than unpolished 6061 aluminum, these sheets are less likely to trap dirt, grease, and grime. A peel-off film shields the surface until you’re ready to work.

The most widely used aluminum, 6061 is made into everything from pipe fittings to containers to airplane parts. It balances strength and corrosion resistance, plus it’s easy to machine and weld.

Make saltwater- and chemical-resistant parts that are easy to keep clean. With a smoother surface than unpolished 5052 aluminum, these sheets are less likely to trap dirt, grease, and grime. A peel-off film shields the surface until you’re ready to work.

At 99% pure, 1100 is among the most conductive, corrosion-resistant, and formable aluminum alloys. Since it’s so soft, it’s often shaped into terminal blocks, raceways, and other parts that don’t need to be hard or strong. For high-stress electrical parts such as bus bars, look to 6101 aluminum instead.
