EN AW-1050A	It is the most pure form of aluminium and the most common plate alloy. The alloy has a good property regarding bending and welding, and it is suitable for surface treatment. It contains 99.5 % aluminium, and they mainly produce it in thickness from 0.5 mm – 6 mm. EN AW-1050A DDQ: It contains 99,5% aluminum and is produced in a very soft temper, making it suitable for deep drawing applications. Mainly produced in thickness 1,00 mm, 1,25 m, 1,05 mm and 2,00 mm.
EN AW-2007	A copper alloy that typically contains between 4.0 and 5.0 % copper, and it is suitable for producing machine parts, bolts and rivets. It looks very much like EN AW-2011, but it is yet a bit harder. It is a short-chipped alloy, which is suitable for treatment, threads and high machining speeds. The alloy has a low corrosion resistance and is not suitable for welding because of the high content of copper. It is not approved by the ROHS.
EN AW-2007 Cast	Like EN AW-2007, but with less tensions and thus more form stabile.
EN AW-2011	A copper alloy that typically contains between 4.0 and 5.0 % copper, and it is suitable for producing machine parts, bolts and rivets. It looks very much like an EN AW-2007, but it is a bit softer. It is a short-chipped alloy, which is suitable for treatment, threads and high machining speeds and gives a shiny surface after treatment. It has a high strength against metal fatigue. The alloy has an inferior corrosion resistance, and it is not suitable for welding because of the high content of copper. It is possibly approved after the ROHS.
EN AW-2014	A copper alloy that typically contains between 4.0 and 5.0 % copper. It is a short-chipped alloy, which is suitable for treatment, and it has a high strength and is thereby as EN AW-2011 and EN AW-2007. It is harder than an EN AW-2011. Typically, you use the alloy for military purposes and for the aviation industry. It is approved after the ROHS.
EN AW-2017A	A copper alloy with a high content of copper. It is a short-chipped alloy, which is suitable for treatment. The alloy has a low corrosion resistance, and it is not suitable for welding because of the high content of copper. It is not suitable for decorative anodising
EN AW-2024	A copper alloy with high content of copper. It is a short-chipped alloy, which is suitable for treatment. The alloy has a low corrosion resistance, and it is not suitable for welding because of the high content of copper. It is not suitable for decorative anodizing.

EN AW-5083	It is sea water resistant and has an average strength, high corrosion resistance and good for welding Medium for anodizing
EN AW-5083 Cast	A moulded and less tensed alloy and its extremely suitable for machining. We stock the alloy with two different surfaces. One with surface milling cut and foil, and suitable, when no finish of the thickness is needed. The other one is not treated and therefore, it is the most suitable for project, where all sides will be treated. Remember that we have a servicecenter that offers sawing on the dimensions that you need.

Temper Descriptions

Name	Translated Name	Description
T6		Solution heat-treated and then artificially aged.
T3		Solution heat-treated, cold worked and naturally aged.
H24		Strain-hardened and partially annealed – 1/2 hard.
H244		Applies to embossed or patterned sheet or strip, fabricated from the corresponding Hxx temper.
H112		Slightly strain-hardened from working at an elevated temperature from a limited amount of cold work (mechanical property limits specified).
T9		Solution heat-treated, artificially aged and then cold worked.
T5		Cooled from an elavated temperature shaping process and then artificially aged.
T7		Solution heat-treated and then artificially overaged.
T6511		Same as T6510 except that minor straightening is allowed after stretching to comply with standard tolerances.
T4		Solution heat-treated and naturally aged.
T8		Solution heat-treated, cold worked and then artificially aged.
H18		Strain-hardened – 4/4 hard (fully hardened).
T651		Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially aged. The products receive no further straightening after stretching.
T1		Cooled from an elevated temperature shaping process and naturally aged.
H34		Strain-hardened and stabilized – 1/2 hard.
H12		Strain-hardened – 1/4 hard
H16		Strain-hardened – 3/4 hard.
T73		Solution heat-treated and then artificially overaged in order to achieve the best stress corrosion resistance.
H19		Strain-hardened – extra hard.
T351		Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and naturally aged. The products receive no further straightening after
H14		Strain-hardened – 1/2 hard.
H114		Applies to embossed or patterned sheet or strip, fabricated from the corresponding Hxx temper.
T3510		Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and naturally aged. The products receive no further straightening after stretching.
T66		Solution heat-treated and then artificially aged – mechanical property level higher than T6 achieved through special control of the process (6000 series alloys).
H22		Strain-hardened and partially annealed – 1/4 hard.
T7351		Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially overaged in order to achieve the best stress corrosion resistance. The products receive no further straightening after stretching.
H111		Annealed and slightly strain-hardened (less than H11) during subsequent operations such as stretching or levelling.
H32		Strain-hardened and stabilized – 1/4 hard.
H42		Strain-hardened and painted or lacquered – 1/4 hard.
T451		Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and naturally aged. The products receive no further straightening after stretching.
O		Annealed – products achieving the required annealed properties after hot forming processes may be designated as O temper.
H44		Strain-hardened and painted or lacquered – 1/2 hard.
T7451		Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially overaged (between T73 and T76). The products receive no further straightening after stretching.
T6510		Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially overaged in order to achieve a good exfoliation corrosion resistance. The products receive no further straightening after stretching.
T4511		Same as T4510 except that minor straightening is allowed after stretching to comply with standard tolerances.
