Grade 1xxx Alloys
Composition
Grade 1xxx Alloys are termed as commercially pure, or controlled unalloyed, with ≤0.30 Silicon, ≤0.50 Iron, ≤0.35 Copper, ≤0.30 Manganese, ≤0.30 Magnesium, ≤0.10 Chromium, ≤0.50 Zirconium, ≤0.20 Titanium, ≤0.05 ≤Boron, ≤0.03 Gallium & ≤0.05 Vanadium
Common Shapes
1xxx Series Alloys are commonly available in
-
Sheets and Plates
-
Drawn and extruded tubes and pipes
-
Structural profiles
-
Extruded wire, rod and bars
-
Rolled and cold finished wires, rods and bars
-
Rivets

(Not all alloys or tempers available in all shapes)
Characteristics
-
Good Workability
-
High corrosion and weathering resistance
-
Low strength
-

Weldability
Welding of Grade 1xxx Aluminium Alloys is easily achieved using GTAW welding techniques. Grade 1xxx Aluminium is also easily joined or added to using brazing or soldering.
Machinability
Grade 1xxx Alloys are not easily machined- they are far better suited to being extruded or drawn into shape.
