About us


Leading Aerospace Aluminium & Marine Alloys Supplier in
Grades 2017, 2024, 5052, 5083, 5086, 5754, 6061, 6082, 7050, 7075, Available in forms of Sheet, Plate, Bar, Extrusions & Forgings.

Metal Ministry Inc is a leading Stockiest & Supplier of Aluminium alloys which is used in Aerospace, Marine, Defence & Auto Industry. 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 available 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
