Grade 2xxx Alloys

Composition

The principle alloying element in Grade 2xxx Aluminium Alloy is Copper, accounting for up to 6.8% by weight. Additional alloying elements include; ≤2.60 Lithium, ≤2.30 Nickel, ≤2.00 Lead, ≤1.90 Tin, ≤1.90 Magnesium, ≤1.50 Iron, ≤1.30 Silicon, ≤1.30 Manganese, 1.00 Bismuth, ≤0.80 Zinc, ≤0.50 Zirconium, ≤0.35 Chromium, ≤0.20 Titanium & ≤0.15 Gallium

Common Forms

2xxx Series Alloys are commonly available in

  • Sheets and Plates

  • Drawn and extruded Tubes

  • Extruded Wire, Rod and Bar and Profiles

  • Rolled and cold finished wires, rods and bars

  • Rivets

(Not all alloys or tempers available in all shapes)

Characteristics

  • Excellent machinability

  • Decent workability

  • Fair corrosion resistance - improved in Alclad form

  • High strength

  • Higher grades may be used in high temperature structures

Uses

  • Automotive parts

  • Structural aircraft assemblies

  • Lorry frames

  • Fasteners

  • Leisure equipment

  • Machine parts and gears

Weldability

Grade 2xxx Aluminium is not best suited to welding in the lower alloys, although some success may be had with Arc and Spot welding techniques. However, in the upper alloy of 2219, excellent welding may be achieved by most common methods, especially in the T tempers.

Machinability

Grade 2xxx Alloys are easily machined, especially in the T tempers.
