CHARACTERISTICS OF SOME ALUMINUM ALLOYS

ALLOY

GENERAL CHARACTERISTICS

SOME USES

1100

99% pure aluminum. Excellent forming qualities weldability, electrical conductivity and resistance in corrosion.

Chemical equipment, tank cars, heat exchanges, storage tanks, sheet metal work, dials and name plates, cooking utensils, reflectors.

2011

Good machining, unexcelled for free cutting qualities with good mechanical properties.

Screw machine products, machine parts, atomizer and hose parts, pipe stems, tube fillings.

2017

Relative high strength, combined with fair workability and good machinability.

Screw machine products, tube fittings, pulleys, gages, coat hangers, tube & tube fittings.

2024 & ALCLAD

A high strength material of adequate workability has largely superseded 2017 for structural applications. 2024-0 is not recommended unless subsequently heat treated. ALCLAD combines the high strength of 2024 with excellent resistance to corrosion in the T3 & T4 temper.

Aircraft parts, truck wheels, piano hinges, luggage, scientific instruments, ski poles, fasteners, orthopedic braces. In ALCLAD .. aircraft frames and skins, venetian blinds, truck bodies, railroad car roofs.

2219

Excellent combination of cryogenic, room temperature and elevated temperature mechanical properties. Excellent resistance to stress corrosion cracking in standard artificially aged tempers.

Welded tanks for cryogenic liquids, high strength structural weldments, and elevated temperture application in the 400F- 500F range.

3003 & ALCLAD

Similar to 1100 but with slightly higher strength, good workability, weldability and resistance to corrosion. Low cost. 3003 H112 Plate: ASME Unfired Pressures Vessel Code Approved. ALCLAD improves corrosion resistance.

Ductwork, ice cube trays, garage doors, awning slats, trailer & truck panels, refrigerator panels, gas lines, gas tanks, heat exchanges, storage tanks, utensils, drawn & spun parts. A very versatile metal. ALCLAD is used for heat exchanger tubes, chemical equipment, swimming pools, tea kettles.

5005

Similar characteristics to 3003 but with finer grain structure. Good finishing characteristics.

Same uses as 3003. Used where excessive finishing costs are encountered in the use of 3003 alloys due to surface roughness upon drawing.

5052

Very good corrosion resistance, good workability, weldability and strength. Tensile range 31-44Kpsi

Used for aircraft fuel tanks, storm shutters, refrigerator liners, utensils, electronic mounting plates and panels, fan blades.

5083

High strength, high resistance to corrosion, suitable for welding. Tensile 40-59Kpsi.

Welded structures (high strength), pressure vessels, storage tanks, truck and marine applications, armor plate.

5086

Similar to 5083, High strength, high resistance to corrosion, good weldability. Tensile 40-54Kpsi.

Medium strength welded structures.

5456

High strength, high resistance to corrosion very suitable for welding. Tensile 46-38 Kpsi

High strength welded structures, pressure vessels, storage tanks, truck and marine applications, armor plate.

6061

99% pure aluminum. Excellent forming qualities weldability, electrical conductivity and resistance in corrosion.

Chemical equipment, boats, truck & bus bodies, scaffolding transmission towers, marine equipment, fire ladders. 6061T6 is used for tankage, tank fittings and general structural and high pressure applications.

7075 & ALCLAD

Very high strength & hardness. ALCLAD also gives excellent resistance to corrosion (in T6).

Used where higher strengths than 2024 are required. Especially used in aircraft parts.
