aluminum alloy 1100 and 3003 is the most broadly utilised aluminum alloy. It’s created up of aluminum, copper, iron, manganese, silicon and zinc. It truly is commonly applied because it has fantastic resistance to corrosion and is moderately robust. The 3003 aluminum coil is 20% stronger than 1100 grade alloys since it is fused with manganese.
Due to the fact it?ˉs not heat treatable, it must be strengthened employing cold functioning alone.
Probably the most popular applications for the aluminum alloy 1100 and 3003 are for fuel tanks, sheet metal operate and also other kinds of projects that need a metal that is stronger than the 1100 series aluminum. In some cases, it really is used for cooking utensils, refrigerator panels, gas lines, storage tanks, garage doors, builder?ˉs hardware and awning slats.
The machinability in the aluminum alloy 1100 and 3003 is regarded as superior for being an aluminum alloy. It is readily machined for the distinctive applications. It may either be formed making use of standard hot functioning or cold functioning. It?ˉs also attainable to make use of standard welding strategies to shape 3003 aluminum. It really is sometimes welded to other aluminum alloys, like 6061, 5052 and 6062, which ought to have an AL 4043 filler rod.
aluminum alloy 1100 and 3003ˉt heat treatable, but it might be forged with heat that?ˉs among 500 and 950 degrees Fahrenheit. When making use of heat within this range, the aluminum is usually hot worked effortlessly. However, it can be readily cold worked, which might be accomplished using standard approaches. When annealing the alloy through or right after employing cold working tactics, it must be performed at 775 degrees Fahrenheit. This will likely give it sufficient time to thoroughly heat prior to being air cooled. The only approach to make this alloy challenging is together with the use of cold operating. It can also be deep drawn, spun or brazed.
