Aluminum

Aluminum- the most commonly processed metal has found many uses due to its corrosion resistance and high strength-to-weight ratio.  Approximately 30 million tons are processed worldwide for a variety of industries. We have also processed aluminum products for all types of industries ranging from aerospace and military to decorative and architectural. Clad form (or Alcad) is also available in some alloys, which is essentially a thin, pure aluminum coating used to protect the base plate.
Some of the most common alloys we process are:

2024 – a high-strength aluminum alloy with low corrosion resistance used primarily in components for transportation and aircraft structures, like fuselages and stringers etc. Because of its low corrosion resistance, anodizing or cladding is highly recommended.  Conforms to AMS-QQ-A-250/4 (5) and ASTM B209 specifications and is heat-treatable.

Grades used (bare and Alcad)

  • 2024-O (annealed)
  • 2024-T4
  • 2024-T351

Sheet and Plate sizes range from .016’’ to 6” thick and 24” to 48” wide.

3003 – a commercially pure aluminum, like 1100, but has manganese added for strength and has excellent corrosion resistance.  Mostly used in food industry or decorative applications.  Diamond tread plate is also available in this grade. Conforms to AMS-QQ-A-250/2 and ASTM B209 specifications and is not heat-treatable.

Grades used (bare and Alcad)

  • 3003-O (annealed)
  • 3003-H14

Sheet and plate sizes range from .016’’ to .750” thick and 36” to 72” wide.

5052– the highest strength of the non heat-treatable aluminum alloys with good resistance to corrosion from salt water and also, good workability making it a widely used aluminum. Conforms to AMS-QQ-A-250/8 and ASTM B209 specifications.

Grades used

  • 5052-O (annealed)
  • 5052-H32 (1/4 hard)
  • 5052-H34 (1/2 hard)

Sheet and plate sizes range from .020’’ to .500” thick and 36” to 96” wide.

6061- the most commonly used heat-treatable aluminum alloy with a wide range of uses including automotive and military, structural and heavy-duty weldments and recreational vehicle components.  It offers good corrosion resistance and good workability.  Diamond tread plate is also available in this grade. Conforms to AMS-QQ-A-250/11 and ASTM B209 specifications.

Grades used (bare and Alcad)

  • 6061-O (annealed)
  • 6061-T4 (heat treated & naturally aged)
  • 6061-T6 (heat treated & artificially aged)
  • 6061-T651 (heat treated, artificially aged & stretch stress relieved)

Sheet and plate sizes range from .020’’ to 12” thick and 24” to 72” wide.

 7075 – one of the highest strength aluminum alloys and is also heat treatable.  The alloy is typically used for structural parts that require a higher strength-to-weight ratio to withstand a high degree of stress and fatigue. Its formability is limited unless annealed. Conforms to AMS-QQ-A-250/9 and ASTM B209 specifications.

Grades used (bare and Alcad)

  • 7075-O (annealed)
  • 7075-T6 (heat treated & artificially aged)
  • 7075-T651 (heat treated, artificially aged & stretch stress relieved)

Sheet and plate sizes range from .010’’ to 8” thick and 24” to 60” wide
