1100 - Aluminum 1100 is low-strength alloy has excellent corrosion-resistance, has satisfactory anodizing and conversion coating
finishing characteristics, and is unmatched by any other commercial aluminum alloy in workability. Aluminum 1100 lends itself readily to welding,
brazing and soldering, but tends toward gumminess when machined. Typical end uses are spun holloware, fin stock, chemical storage, and processing
equipment, kitchen utensil items, and general sheet metal work.
3003 - Aluminum 3003 is about 20% higher in strength than aluminum 1100 but retaining an excellent workability rating. May show some slight
discoloration when anodized, but reacts well to mechanical and organic finishings. Aluminum 3003 is easily welded and brazed, but soldering is limited to the
torch method. Like 1100, tends to be gummy when machined, but will perform somewhat satisfactorily in the higher tempers with the proper set-up
and maximum speeds. Typical end uses include food and chemical handling equipment, appliance components, truck/trailer roofing, heat exchangers,
pipe jacketing and lawn furniture components.
5005 - Aluminum 3005 is comparable to aluminum 3003 in strength and close to it in formability, but this alloy has superior finishing
characteristics making it much better for anodizing. Excellent corrosion-resistance and weldability. It would rate somewhat below aluminum 1100 and 3003 for
brazing and soldering, and it is not the alloy one would choose for machinability. Typical end uses are decorative trim, utensils, mobile home siding
5052 - For many years, until the advent of aluminum 5083 and 5086, aluminum 5052 alloy was the highest strength non-heat-treatable
alloy commercially available. Although easily welded, it is not recommended for brazing and soldering applications. Excellent corrosion-resistance,
particularly in marine applications, and adapts to most mechanical and finishing processes although the heavier anodic films may take on a yellowish
cast. Fair machining with proper set-up. Typical end uses of aluminum 5052 include fuel tanks, truck-trailer side panels, small boat hulls, truck cabs,
bumpers, storage tanks and pressure vessels.
5083 - Aluminum 5083 has excellent corrosion-resistance and weldability, together with high strength. The Aluminum 5083 alloy was designed
for welded structures requiring maximum joint strength and efficiency. Aluminum 5083 can be anodized for increased corrosion-resistance, but does not lend itself to decorative
applications. Not meant to be a machining alloy, aluminum 5083 can be machined fairly well with proper preparations. because of its relatively high magnesium
content, the workability rating would be only fair. Typical end uses are large marine craft, containers, railroad cars, structurals and elevator cars.
5086 - Aluminum 5086 has excellent corrosion-resistance and weldability. Can be anodized for increased corrosion-resistance, but does not
lend itself to decorative applications. Not meant to be a machining alloy, but can be machined fairly well with proper applications. Because of
its relatively high magnesium content, the workability rating would be only fair. Typical end uses for aluminum 5086 are marine craft, containers, railroad cars,
structurals and elevator cars.
5383 - The aluminum 5383 alloy offers a 15% higher welded strength than standard aluminum 5083 and may be used wherever a stronger welded
aluminum structure is desired, from hulls to superstructures. Marine structures benefit from the excellent corrosion-resistance offered by aluminum 5383.
Smaller boats (< 168 ft) benefit from improved scantlings, which translate into structural weight savings on patrol craft, increased strength on work
boats and added interior space in luxury yachts. Larger vessels (> 168ft ) profit from the increased strength and improved fatigue behavior of the aluminum
5383 alloy. Cruise ship superstructures can be lightened further while improving stability and not compromising strength or corrosion-resistance.
5456 - Aluminum 5456 is the highest in strength of the commercially available non-heat-treatable alloys with excellent corrosion-resistance.
Only fair workability and machinability, but excellent weldability. Aluminum 5456 is not recommended for brazing or soldering. Typical end uses are high-strength
welded structures, marine components, pressure vessels and storage tanks.
6061 - Aluminum 6061 has very good corrosion-resistance and finishability plus excellent weldability and a strength level approximating that of
mild steel, this is a popular general-purpose alloy. Machinability is good and, in the annealed state, its workability carries a high rating, staying at the
"good" level if heat-treated without aging. Typical end uses for aluminum 6061 are aircraft landing mats, large and small marine vessels, structural architectural
parts, storage tanks and highway signs.
6063 - Aluminum 6063 is a heat-treatable alloy developed exclusively for the extrusion industry and the most important alloy in the magnesium
silicide group. Its as-extruded finish is quite good making it satisfactory for many applications without any additional work. Aluminum 6063 lends itself to
comparatively intricate sections making it the leading architectural extrusion alloy. Aluminum 6063 also finds use in some decorative applications, furniture
tubing and ladder parts.
