Aerospace Marine Aluminium Alloys

METAL MINISTRY INC IS A LEADING AEROSPACE & MARINE ALUMINIUM ALLOYS SUPPLIER IN
GRADES 2017, 2219, 2024, 5052, 5083, 5086, 5754, 6061, 6082, 7050, 7075, AVAILABLE IN FORMS OF SHEET, PLATE, PIPES, BAR, EXTRUSIONS & FORGINGS. We are a leading supplier of high-grade aluminium alloys, which are tailor-made mixtures of aluminium and other metals to enhance and enrich material properties which are avail

able with us as per ASTM, AMS, and ASME specification cross references for typical aluminium alloys and forms. We stock wide variety of aluminium grades in many different forms, such as wire, foil, strip and sheet, rod, bar, angles, channels, Extrusions, tube, pipe, and plates. Aluminium alloy series available with us.

1000's - Aluminium 99% min. - excellent corrosion resistance, high thermal and electrical conductivity, low mechanical properties
2000's - Copper - high mechanical properties, increased yield strength, best known and most widely used aircraft alloy
3000's - Manganese - good workability and weldability, high corrosion resistance, moderate strength
4000's - Silicon - low melting point, widely used in welding wire and as a brazing alloy
5000's - Magnesium - moderate to high strength, good welding characteristics, good resistance to corrosion, especially in marine environments
6000's - Magnesium/Silicon - good formability and corrosion resistance, moderate strength
7000's - Zinc - highest strength alloy available, used in air-frame structures and for highly stressed parts 8000's - Other element
Aluminium Association Alloy Designation System

1st digit - Identifies alloy types.
2nd digit - Identifies alloy modifications. Digit replaces letters formerly used.
3rd and 4th digits - Identifies the aluminum purity of the specific aluminum alloy. The digits are the same as the numbers in the old designations for alloys in use prior to the adoption of the four-digit system. Temper Designations

H-Tempers: Strain-Hardened
H1 - strain-hardened only. H2 - strain-hardened and partially annealed. H3 - strain-hardened and stabilized by low-temperature thermal treatment. The digit following H1, H2, or H3 indicates the temper:

2 –1/4Hard
4 – 1/2 Hard
6 – 3/4 Hard
8 – Full Hard
9 – Extra Hard
T-Tempers: Heat-Treated

T1 - cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition
T2 - annealed (cast products only)
T3 - solution heat-treated and then cold worked
T4 - solution heat-treated and naturally aged to a substantially stable condition
T5 - cooled from an elevated temperature shaping process and then artificially aged
T6 - solution heat-treated and then artificially aged
T7 - solution heat-treated and then stabilized
T8 - solution heat-treated, cold worked, and then artificially aged
T9 - solution heat-treated, artificially aged, and then cold worked
T10 - cooled from an elevated temperature shaping process, artificially aged and then cold worked
Additional digits for T tempers include the following:

T51- stress relieved by stretching
T510- receives no further straightening after stretching
T511- receives minor straightening after stretching to comply with standard tolerances
T52 – stress relieved by compressing
T54 – stress relieved by combined stretching and compressing
