Alloy 6082 Aluminum Plate
Sheet
Aluminum alloy
6082 plate sheet is a medium strength alloy with excellent corrosion resistance.
It has the highest strength of the
6000 series alloys. Alloy 6082 is known as a structural alloy. In plate form, alloy
6082 aluminum plate sheet i is the alloy most commonly used for machining. As a
relatively new alloy, the higher strength of 6082 has seen it replace 6061 in many
applications. The addition of a large amount of manganese controls the grain
structure which in turn results in a stronger alloy. In the T6 and T651 temper,
alloy 6082 machines well and produces tight coils of swarf when chip breakers are
used.
TEMPER
TYPES
The most common tempers
for 6082 aluminium are :
• T6 - Solution heat
treated and artificially aged
• O - Soft
• T4 - Solution heat
treated and naturaly aged to a substantially stable condition
• T651 - Solution heat
treated, stress relieved by stretching then artificially aged
Alloy 6082 Aluminum Plate
sheet
Alloy 6082 aluminium plate
sheet alloys contain magnesium and silicon as the major alloying
elements.
Strength
Moderately high levels of
strength are obtained through heat treating to the T651 condition, giving higher
strength levels than 5XXX series alloys.
Machinability
6082 aluminium plate alloys
in the T651 condition are easier to machine than 5XXX alloys.
Forming
6082 aluminium plate
alloys can be cold formed in the T651 or T451 temper. Formability is better in
the T451 than the T651 temper and increases with decreasing
thickness.
Corrosion
resistance
6082 aluminium plate alloys,
in the T651/T652/T6 temper, have good corrosion resistance. Unlike some 5XXX
alloys, 6XXX aluminium plate alloys do not suffer degradation in corrosion
resistance after exposure to elevated temperatures.
Welding
6082 aluminium plate alloys
are readily weldable by either GTA-W or GMA-W processes provided that a suitable
filler material is used. Welding reduces the tensile strength to 165-200 MPa in
the heat affected area. In special circumstances, a post weld heat treatment can
be applied to restore some of the lost strength in this area.
6082-T651 and 6061-T651 are
now superseding low-carbon steels in structural applications where the benefits
of lightness, specific stiffness, corrosion resistance and ease of fabrication
can be exploited:
