Which aluminium grade do I need?
A quick guide to choosing the right aluminium for your project.
Aluminium grade 5005 — Great for general fabrication
Good for:
Sheetmetal projects
Folding and forming
General DIY fabrication
Architectural applications
Why choose aluminium grade 5005?
Easy to form, good corrosion resistance and gives a nice finish. A really useful all-rounder when you don’t need high structural strength.
Aluminium grade 5052 — Stronger + great around moisture
Good for:
Marine components
Fuel tanks
Trailers
Enclosures
Outdoor fabrication
Why choose aluminium grade 5052?
Stronger than 5005, very corrosion resistant and still has good forming and welding properties. A good choice when your project needs a bit more toughness.
Aluminium grade 5083 — Heavy-duty + marine
Good for:
Boats
Marine structures
Tanks
Transport applications
Heavy fabrication
Why choose aluminium grade 5083?
High strength with excellent resistance to seawater and harsh environments. Think serious fabrication rather than your average DIY sheetmetal project.
Aluminium grade 6061 — Strong + machinable
Good for:
Structural components
Frames
Machinery parts
CNC-machined components
Automotive fabrication
Why choose aluminium grade 6061?
A strong, versatile alloy that's excellent for machining and can also be welded. Common when strength and precision matter.
Aluminium grade 6063 — The extrusion specialist
Good for:
Aluminium angle
Channels
Tubes
Frames
Architectural trim
Window and door components
Why choose aluminium grade 6063?
Excellent for extrusion, with a smooth surface finish and good corrosion resistance.
If you're buying aluminium in a shaped profile rather than sheet, there's a good chance you'll come across 6063.
Not sure what you need?
General sheet fabrication → 5005
Outdoor / tougher fabrication → 5052
Marine / heavy duty → 5083
Structural / machined parts → 6061
Extruded profiles → 6063
