Introduction

Aluminium / Aluminum alloys have strong corrosion resistance. They are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F), and can lose some of their strength. However, the strength of Aluminium / Aluminum alloys can be increased at subzero temperatures, making them suitable low-temperature alloys.

Aluminium / Aluminum 5005 alloy is a non-heat treatable alloy with small amount of magnesium content. It has excellent corrosion resistance and weldability characteristics. The following datasheet will provide more details about Aluminium / Aluminum 5005 alloy.

Fabrication and Heat Treatment

Machinability

Aluminium / Aluminum 5005 alloy has poor machinability in the soft temper conditions. However, the alloy can be machined, but is a lot tougher than many of the other aluminum alloys. The alloy in the harder tempers such as H34 and H38 can be machined better than the alloy in the soft temper condition.

Forming

Formability of Aluminium / Aluminum 5005 alloy, especially in the softer tempers, can be easily achieved using conventional methods.

Welding

Aluminium / Aluminum 5005 alloy has excellent welding capacity. Welding is possible using all the commercial methods. Filler metal of the same alloy has to be used. Welding using resistance method of the O or annealed temper material requires some trial and error determination.

Heat Treatment

Aluminium / Aluminum 5005 alloy cannot be heat treated, except when annealed to minimize cold working strain.

Forging

Aluminium / Aluminum 5005 alloy is forgeable.

Hot Working

Aluminium / Aluminum 5005 alloy does not require hot working in most cases. But if it is required the preferable temperature range is 371 to 204°C (700 to 400°F).

Cold Working

Aluminium / Aluminum 5005 alloy has excellent cold working capacity including the harder tempers.

Annealing

Annealing can be performed at 343°C (650°F) if required. This should be followed by air cooling.

Hardening

Aluminium / Aluminum 5005 alloy can be hardened only by cold working.

Applications

Aluminium / Aluminum 5005 alloy is widely used in the manufacture of the following products:

  • Small boats
  • Appliances
  • Utensils
  • Gas lines
  • Refrigerator panels

The 5005 alloy can also used in architectural parts and as an electrical conductor. It is very useful to avoid excessive finishing costs when using the 3003 alloys due to surface roughness while drawing.
