2014 T6 Aluminium Plate

2014 is a heat-treatable aluminium–copper plate. Strength, machinability, and behaviour at elevated temperature are the reasons it is specified for truck frames, airframe structure, fuel tanks, and other high-temperature parts. The same sheet is used in aerospace, military, and automotive work.

Renaissance Fittings & Piping Inc. supplies 2014 and 2014A sheet, plate, and forged plate block. Open-die forging envelopes for this alloy are on the 2014 T3 forging page. Tube in the same alloy is 2014 extruded tube.

Standards

Inventory sizes below are called up to ASTM B209, EN 485, AMS-QQ-A-250/3, and AMS 4029.

Equivalent names

EN-AW 2014, UNS A92014, ISO AlCu4SiMg, BS H15, CSA CS41N, AA2014-T651, DIN AlCuSiMn, NF A-U4SG, Al2014-T6.

Tempers

Hot-selling tempers: O, T3, T4, T6, T451, T651.

Also named: F, T351, H112. T651 is a pre-stretched temper. The stretch is used to take out internal stress, which is why that temper is chosen for moulds and machined parts where movement during milling has to stay small.

The grade sheet also prints 2024-T6 and 2024-T651 in the same temper line as 2014-O, 2014-T4, 2014-T3 clad, 2014-T4 clad, and 2014-T6 clad.

Supply range

Length up to 20 m, fixed, cut-to-length, or to the drawing. Plate can be produced at widths under 2800 mm. Small pieces can be sawn.

Coating: black and white film, blue film, or transparent film, 50 µm or 80 µm.

Surface: bright, polished, hairline, brush, sand blast, checkered, embossed, etching.

Regular blank sizes: 1525 × 3660 mm and 1250 × 2550 mm.

Regular thicknesses: 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 100, 110, 120, 150, 160, 180, 200, and 250 mm.

Chemical composition

Figures are the published composition percentages for 2014A and 2014.

Mechanical properties

Minimum values. Elongation is measured on 50 mm. The five elongation columns are the gauge thicknesses 0.5, 0.8, 1.3, 2.6, and 3.0 mm. A dash means that column is not published for the row.

Density used for piece weight is 2.73 g/cm³.

Where each product is used

Alclad 2014 sheet is used for aircraft skin, skeleton, rib beams, and frames. The same high-strength plate is used for trucks and suspension parts, propeller components, moulds, and high-strength machined parts.

T4 plate is used where strength has to hold at elevated temperature: missile parts, first-stage fuel tanks on multi-stage rockets, and spacecraft parts.

T651 plate is used where strength and hardness are both required, including at elevated temperature: aerospace parts, wheels, tanks, primary structure, and heavy forgings for truck frames and suspension, as well as sheet.

Forged 2014 plate block is used for moulds, high-strength structure, truck hubs, precision parts, missile parts, first-stage rocket tanks, spacecraft parts, oxygen equipment, and shipbuilding.
