We offer Aluminum Alloy merchandise in the following Aluminum Alloys:
Aluminum 1100 is the most commercially pure alloy of all the aluminum grades. It is composed of 99% aluminum and 0.12% copper. Aluminum 1100 is a soft and low-strength alloy that offers strong corrosion resistance. It offers excellent machinability and formability (hot or cold forming), while maintaining its strength. It is also a good electrical conductor and excellent for welding. Aluminum 1100, however, does not respond to heat treatment other than to produce the annealed condition or the desired temper. In our case, our Aluminum 1100 are H14-tempered or strain-hardened to 1/2 hard.
Aluminum 5083 offers the highest strength of all non-heat treatable alloys. The material is known for its exceptional performance in extreme environments. It is highly resistant to chemical attacks by both seawater and industrial chemical environments. Alloy 5083 retains exceptional strength after welding. However, it is not recommended for use in temperatures above 65°C. It is also capable of withstanding extremely low temperatures without brittleness or loss of properties.
In the tempered condition, 5083 is strong, and retains good formability due to its excellent ductility. It has a high resistance to corrosion, which is ideal for marine applications.
Aluminum 6061 is one of the most commonly available and extensively used aluminum alloys. This alloy has medium to high strength, good formability and machinability. It can be anodized and has good weldability and brazeability. It also has excellent corrosion resistance to atmospheric conditions and good corrosion resistance to sea water. Aluminum 6061-T6 is solution heat-treated and artificially aged. T6 tempered Aluminum 6061 have relatively higher shear, tensile and yield strengths than plain 6061 and can be less easy to cold form. In market practice, T651 temper is usually for thicker sheets, but have relatively similar mechanical characteristics to T6.
Aluminum 2017 is a heat treatable wrought alloy that offers decent strength, ductility, and good machinability. The material has very excellent machining characteristics specially under T4 temper.
Welding tends to reduce corrosion resistance, hence should be avoided whenever possible. If welding is required, heat treatment should be performed after welding to restore corrosion resistance. The preferable welding techniques are inert gas welding and resistance welding.
Cold working, such as shaping and bending may easily be accomplished by conventional means for 2017 alloy. Ease of cold working is best with the alloy in the T4 temper.
