alloys and it application
aluminum is soft and ductile, it is not suitable in most of
the engineering environment. However, special mechanical strength
can be achieved by the adding other elements to further strengthen
it. In general, Aluminum alloy can be classified into two
1. The non-heat-treatable aluminum alloy (alloyed with manganese,
silicon, iron, and magnesium) and
2. The heat-treatable aluminum alloys (alloyed with copper,
magnesium, zinc, and silicon).
Aluminum is available in a wide variety of alloys to meet
specific applications. Following are some of the most commonly
used in the precision sheet metal industries.
Pure aluminum with high chemical resistant and weather prove.
Excellent for chemical processing equipment and other uses
where product purity is important. Easily worked and welded,
ductile enough for deep draws. It is a lowest strength aluminum
alloy in the market. Mostly Use for light reflectors, decorative
and jewelry parts, name plates.
General purpose manganese alloy, stronger than 1100 Aluminum.
Good formability and low cost. Fine corrosion resistance and
weldability. Used in stampings, spun and drawn parts, mail
boxes, cabinets, tanks, fan blades.
Aluminum alloy with higher magnesium contained. Strong mechanical
strength compare to 1100 and 3003. Best suit for deep drawn
process with reasonable inside drawn radius. Good corrosion
resistance and weldability. Mostly use on electronic chassis,
tanks, pressure vessels and parts required good strength and
formability. My be slight yellowish after anodized.
Aluminum alloys contained magnesium & silicon. Mechanical
strength, weldability, corrosion resistance can be improved
by proper heat treatment. Widely used for light to medium
strength applications. Requires much larger inside drawn radius
than 5052-H32 in the deep drawing process.
