About aluminium alloys

Aluminium alloys (6061, 7075, 2024, 5052, 2195): strength by temper, composition and corrosion data with sources.

Aluminium alloys are named by series: 2xxx (copper), 5xxx (magnesium), 6xxx (magnesium and silicon), 7xxx (zinc). Strength depends on the temper, so each value on these pages names its temper (O, H32, T4, T6, T651) and product form.

At a glance

Highest yield strength: Aluminium-lithium alloy 2195 reaches 510 MPa. Lowest: Aluminium starts at 29 MPa. (26 of 31 grades have a sourced value.)
Highest tensile strength: Aluminium alloy 7075-T6 reaches 572 MPa. Lowest: Aluminium alloy 1050 starts at 60 MPa. (29 of 31 grades have a sourced value.)
Highest density: Aluminium alloy 2219 reaches 2.84 g/cm³. Lowest: Aluminium alloy 5019 starts at 2.64 g/cm³. (28 of 31 grades have a sourced value.)

Ranges run across the conditions each source reports (temper, heat treatment, form), measured at room temperature where the source says so.

How they compare

The same measurements for every material in the collection. A range means the grade has values under several conditions; "at least" means the source gives a specified minimum. "no data" means no sourced value yet. For ranked tables, open a benchmark.

Material	Best for	Weakest at
Aluminium alloy 6061	A light, workable structural metal with good corrosion resistance (the NASA handbook ranks 6061 best of the heat-treatable aluminium alloys for corrosion)	Galvanic attack when coupled to more noble metals, especially in sea water (NASA handbook); typical strength values are marked not for design
Aluminium alloy 7075-T6	High-strength aluminium parts where low mass and wrought forms such as tube, plate, bar or forging are useful	Stress-corrosion cracking in the short-transverse direction in T6, and relatively poor corrosion resistance in industrial and marine environments
Aluminium alloy 2024	A high-strength wrought aluminium alloy for aircraft fittings and structural parts (the datasheets list these uses; ASM typical T4 yield strength is 324 MPa)	Stress-corrosion cracking of the 2024-T351 temper in seacoast and salt-water conditions (NASA 1981), and pitting in salt water
Aluminium alloy 5052	Welded sheet and tank or marine-style parts at medium strength, where the temper is named and checked (the datasheets rate its seawater resistance very good)	Strength depends on temper (yield 13 ksi annealed to 37 ksi in H38), and no measured seawater corrosion rate was found in the sources read
Aluminium-magnesium alloys (5XXX series)	Welded, corrosion-resistant sheet and plate at moderate strength (5083 is sold for ship building and pressure vessels)	Strength per alloy is modest next to heat-treated 6061, and 5083 is not recommended above 65 °C because of grain-boundary attack
Aluminium-lithium alloy 2195	Welded cryogenic tanks where friction stir welding keeps most of the strength (NASA reports, 1998 to 2008)	Fusion welding, which hot-cracks and needs repairs, and corrosion resistance, which the supplier calls poor
Aluminium	Light, cheap electrical and thermal conduction, and a positive-electrode foil that stays passive in common lithium-ion electrolytes	Strength: annealed pure aluminium has a typical yield strength near 22 to 29 MPa, so it is not a structural metal on its own
Aluminium alloy 1050	Formed sheet, chemical plant and heat-transfer parts that need very good corrosion resistance and easy forming more than strength (Smiths and Righton list these uses)	Low strength in the soft tempers (Smiths gives 100 to 135 N/mm2 typical tensile for 1050A H14, and 1200 O is 70 to 105 N/mm2); no measured corrosion test data were read
Aluminium alloy 2011	Small, complex, high-precision machined parts made on automatic lathes, such as screws, bolts, gears, fasteners and fittings (suppliers rate machinability very good to excellent)	Weldability (rated poor to extremely poor by the sources) and corrosion resistance (rated low to moderate, and anodising or another surface treatment is advised)
Aluminium alloy 2014	High-strength structural parts for aerospace and defence, where a 460 MPa minimum tensile strength in T651 plate is needed and the part is clad or painted against corrosion	Corrosion resistance (poor in water and salt, with pitting and galvanic attack in sea water), and welding, which is difficult and prone to cracking
Aluminium alloy 2017	High-strength machined parts and rivets in aircraft-type structures, in the T4 temper (supplier rates machinability excellent, strength very good)	Weldability (only resistance welding is suitable, per the AircraftMaterials datasheet) and corrosion resistance (rated moderate by the supplier, with no test data found for this grade)
Aluminium alloy 2017A	Machined structural parts and solid rivets in the T4 temper (supplier rates machinability Excellent, yield strength 276 MPa)	Welding (resistance welding only, per the Smith and AircraftMaterials datasheets) and corrosion resistance (rated moderate by one supplier and good by another, with no test data for this grade)
Aluminium alloy 2219	Launch-vehicle and cryogenic tankage where weldability and fracture toughness matter (Smith datasheet: readily weldable, good fracture toughness; Alloys International: launch vehicle and cryogenic tanks)	Ductility in thick plate, where 5-inch T87 plate showed below 1 % in the short-transverse direction (NASA 2021), and general corrosion resistance, which Wikipedia describes as lower than other aluminium alloys
Aluminium alloy 2319	Welding 2219 and other Al-Cu aerospace structures and propellant tankage, where the weld is made with MIG or TIG wire (AircraftMaterials; NASA TM X-64659)	Weld strength. In the 1972 NASA TIG study, welds made with M-934 filler were 7 to 18 percent stronger than 2319 welds at ambient temperature.
Aluminium alloy 2618A	Forged or extruded rotating parts, pistons and hot structural parts that must keep strength near 200 °C (Smiths datasheet and AircraftMaterials)	Fusion welding (not recommended by the supplier) and atmospheric corrosion resistance, which the supplier rates only fair to medium without protection
Aluminium alloy 3003	Sheet and formed parts that need moderate strength, good workability and weldability, and resistance to atmospheric corrosion, such as storage tanks, chemical equipment and heat exchangers, with the temper named	Strength depends on temper, from 14 to 19 ksi tensile in O to 27 ksi minimum in H18, and no seawater rating or measured corrosion rate for 3003 was found in the sources read
Aluminium alloy 3103	Heat exchangers, radiators and formed sheet that need moderate strength, good weldability and resistance to atmospheric corrosion (Smiths lists these uses)	Strength falls with the softer tempers (O is 90 to 130 N/mm2 against 160 to 195 N/mm2 in H16), and the sources read here give no measured corrosion test data for this alloy
Aluminium alloy 4047	Brazing and welding filler for aluminium parts where a low melting range and reduced hot cracking matter (suppliers cite high fluidity and low shrinkage)	Low strength in the as-welded form (about 124 MPa tensile and 55 MPa yield, supplier data) and no sourced property data for brazed joints
Aluminium alloy 5019	Wrought rod, tube and wire where seawater and weathering resistance matter (supplier rates both very good)	Thin data: no yield strength was found for any tested temper, and the supplier rates hard brazing as poor
Aluminium alloy 5056	Cold-formed wire, rivet and bolt stock, and hinge pins that must resist corrosion in salt water (supplier statement)	Strength depends strongly on temper: the O temper tops out at 46 ksi tensile, against 50 ksi minimum for H34, and no yield strength for 5056 was found in the sources read
Aluminium alloy 5083	Welded marine structures and pressure vessels kept at or below 65 °C, where seawater resistance and strength matter (supplier datasheets)	Service above 65 °C, where the suppliers advise against use. It is a non-heat-treatable alloy (Dinco sheet). No space-environment data were found.
Aluminium alloy 5251 (AlMg2)	Welded marine and sheet-metal structures where seawater corrosion resistance and weldability matter more than peak strength, at 2.69 g/cm3	Strength compared with heat-treatable alloys: H22 minimum proof stress is 120 MPa, and a good weld reaches only about 160 MPa (Smith)
Aluminium alloy 5754 (AlMg3)	Welded structures and marine or chemical service where seawater corrosion resistance matters, at a density of about 2.67 g/cm3	Strength against heat-treatable aluminium alloys, since strength comes from the temper, and the risk of sensitisation in magnesium-rich grades held warm for long periods (no temperature threshold for this grade was verified)
Aluminium alloy 6013	Light structural aluminium for aerospace and general structural use: 2.71 g/cm3 density, and 350 MPa yield in the T651 temper (supplier page)	Dust and chips ignite readily during machining (Hydro SDS). No fatigue, fracture-toughness or T6 temper data was opened, and the sources disagree on thermal expansion
Aluminium alloy 6063	Architectural extrusions such as window and door frames, rails and trim that need a smooth anodised finish (Alloys International; AZoM).	Strength: Alloys International says 6061 is the higher-strength choice for structural parts, and no space-environment, cryogenic or galvanic data were found for 6063.
Aluminium alloy 6082	Structural parts that must be strong but light: T6 and T651 plate with minimum proof stress 255 MPa and density 2.70 g/cm3	Strength in the weld zone, which the supplier says is lowered by welding, and pitting or intergranular attack in chloride solution (lab immersion test at 50 °C)
Aluminium alloy 6101	Electrical bus-bar and power-distribution conductors where conductivity matters more than peak strength (57 % IACS in T6, per TubingChina)	Strength depends strongly on temper (H111 tensile 85 MPa against 32,000 psi in T6), and the 6101 sources read here partly disagree
Aluminium alloy 7050 (AA7050)	Thick, high-strength aerospace structure in the over-aged T74 or T7451 conditions, where high yield strength and good exfoliation resistance are needed	Weld zones: friction-stir welds of 7050-T7451 showed less cracking resistance than 7075-T651 welds in constant extension rate tests (2003 study)
Aluminium alloy 8011 (AA8011)	Thin, light foil and fin stock: 2.71 g/cm3 density with 210 to 220 W/(m·K) thermal conductivity in H19 foil at 20 °C	Yield strength and corrosion data are missing from this profile, and no spacecraft use was found in any source read
Au-Al IMCs	Gold-to-aluminium bonds on chips that are kept cool and free of halide contamination, where the joint must carry current for a long time at moderate temperatures (KJMM 2025 and the background of US patent 5184206)	Long exposure above about 175 degC, which grows voids in the joint; the sources read here give no melting point, density, hardness or strength for the phases
Aluminium master alloys	Melting aluminium alloys where a fine grain structure or a controlled addition of Ni, Mn or Zr is needed (the Al-Ti-B and Al-Zr refiners; the Al-Mn and Al-Ni additions)	These are intermediate alloys, not structural materials. The sources read here give no density, no mechanical properties and no corrosion test for any of these master alloys, and the Al-Zr and Al-Mn densities are printed without a unit
