5052 (UNS A95052) is alloyed with 2.5% magnesium. Tensile strength range 31,000 to 44,000 psi. Very good corrosion resistance, good workability, weldability and strength. Used for aircraft fuel tanks, storm shutters, refrigerator liners, utensils, electronic mounting plates and panels, fan blades, etc. Conforms to Federal specification QQ-A-250/8 and ASTM B-209.
5O83 (UNS A95083) is alloyed with 4.45% magnesium, 0.65% manganese and 0.15% chromium. Tensile strength range: 40,000 to 59,000 psi. For use in structures requiring high weld efficiency for maximum joint strength — plus light weight and corrosion resistance. Applications: marine components, truck bodies, construction equipment, tanks, structural towers, drilling rigs, cryogenic applications, etc. Conforms to ASTM B209 and Federal specification QQ-A-250/6.
5086 (UNS A95086) is alloyed with 4.0% magnesium, .45% manganese and 0.15% chromium. This alloy has a typical tensile strength range of 40,000 to 54,000 psi. It offers resistance to stress corrosion and superior resistance to atmospheric corrosion plus good general workability. Applications include tanks (stationary, trailer and rail-car), marine components and welded assemblies of all kinds. Conforms to Federal specification QQ-A-250/7 and ASTM B-209.
5454 (UNS A95454) is alloyed with 2.7% magnesium, 0.8% manganese and 0.12% chromium. Tensile strength range 36,000 to 47,000 psi. Good formability, weldability and corrosion resistance. Uses include pressure vessels (ASME code approved for up to 400° F.), tanks, dumptruck bodies, welded structures, etc. Conforms to Federal specification QQ-A-250/10 and ASTM B-209.
HEAT TREATABLE (STRONG) ALLOYS
2O24 (UNS A92024), is alloyed with 4.5% copper. Tensile strength range 30,000 to 63,000 psi. Fair workability and corrosion resistance. Forming operations are limited. Used for high strength structural and aircraft applications. Also available as Alclad for improved corrosion resistance. 2024 conforms to Federal specification QQ-A-250/4 and ASTM B-209.
6O61 (UNS A96061) is alloyed with 1.0% magnesium and .6% silicon. Tensile strength range 20,000 to 42,000 psi. Good formability, weldability and corrosion resistance. Used for engineering and structural applications, boats, furniture, transportation equipment, etc. Conforms to Federal specification QQ-A-250/11 and ASTM B-209.
7O5O is alloyed with Zinc (5.7-6.7%), Copper (2.0-2.6%) and Magnesium (1.9-2.6%) to offer superior strength, stress corrosion resistance and toughness. Stocked in T7451 (formerly T73651), a temper intermediate to T3 and T76. Used in aircraft and missile applications. Conforms to AMS 4050, MMS1420, BAC 5439 Class A, BMS 7-323 and MIL-STD 2154.
7O75 (UNS A97075) and Alclad 7075are heavily alloyed with zinc with lesser amounts of magnesium, copper and chromium. One of the strongest of the aluminum alloys, its use parallels that of 2024 with 7075 selected when higher mechanical properties are desired. Forming operations are limited. Also available as Alclad for improved corrosion resistance. All 7075 flat products conform to ASTMB-209; 7075 Bare conforms to Federal Spec QQ-A-250/12, Alclad 7075, QQ-A-250/13.
WEIGHT CONVERSION FACTORS
Once you know the weight of a particular size of sheet or plate in a given alloy, it is easy to determine the appropriate weight for alternative alloys by using these conversion factors.
