Aluminum Alloy Flanges

We are one of the most quality conscious producers of the wide range of Aluminum alloy flanges.

Aluminum is one of the most popular non-ferrous metals to be used in construction, engineering, and industry, and it is not surprising at all. There are not many materials out there that are as durable, workable, and versatile as aluminum alloys. An aluminum alloy is a composition consisting mainly of aluminum to which other elements have been added.

Aluminum Alloy 3003 Flanges

3003 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It can be cold worked (but not, unlike some other types of aluminium alloys, heat-treated) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys, 3003 is a general-purpose alloy with moderate strength, good workability, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged. As a wrought alloy, it is not used in casting. It is also commonly used in sheet metal applications such as gutters, downspouts, roofing, and siding.

6061 aluminium alloy Flanges

6061 is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements. It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063). It is one of the most common alloys of aluminum for general-purpose use.

It is commonly available in pre-tempered grades such as 6061-O (annealed), tempered grades such as 6061-T6 (solutionized and artificially aged) and 6061-T651 (solutionized, stress-relieved stretched and artificially aged).
