3003 aluminium coil is approximately 20% stronger than 1100 series aluminium. This alloy is readily formed by either conventional cold working or hot working. Huawei offers 3003 aluminium coil, coil and tread coil covered by the ISO standard 6361 and the ASTM standards B209, B210, B211, B221, B483, B491, and B547. The 3003-H14 is a softer, more formable aluminium coil and 3003 tread coil offers increased rigidity in the material as well as hiding fingerprints and dents. Commonly used tempers include H14, H16 and H18 while others are also available by customers’ demands.

3003 aluminium reacts well to mechanical finishings as well as organic finishes. 3003 welding is readily accomplished by means of conventional welding methods, but may be gummy if machined. Soldering is limited to the torch method.

3003 aluminum coil is the most widely used aluminum alloy. It is made up of aluminum, copper, iron, manganese, silicon and zinc. It is commonly used because it has great resistance to corrosion and is moderately strong. The 3003 aluminum coil is 20% stronger than 1100 grade alloys because it is fused with manganese.

The machinability of the 3003 Aluminum is considered good for being an aluminum alloy. It is readily machined for the different applications. It can either be formed using conventional hot working or cold working. It’s also possible to use conventional welding methods to shape 3003 aluminum. It is sometimes welded to other aluminum alloys, like 6061, 5052 and 6062, which should have an AL 4043 filler rod.

AL 3003 isn’t heat treatable, but it can be forged with heat that’s between 500 and 950 degrees Fahrenheit. When using heat in this range, the aluminum can be hot worked easily. However, it is readily cold worked, which can be done using conventional methods. When annealing the alloy during or after using cold working techniques, it should be performed at 775 degrees Fahrenheit. This will give it enough time to thoroughly heat before being air cooled. The only way to make this alloy hard is with the use of cold working. It can also be deep drawn, spun or brazed.

3003 h14 aluminum coil

3003 is the American AA Aluminum Association alloy, H indicates the cold working hardening state, and the following numbers indicate the different degrees and types of cold working hardening.

The 3003 h14 aluminum coil is a medium strength alloy that is made with 1.20 percent manganese. It is 20 percent stronger than 1100 series aluminum, which is why it’s a preferred metal and used for various applications in different industries. It has great resistance to corrosion, can be welded easily and has excellent workability. It can be used for sheet metal works, spinning, drawing, fuel tanks, tapping, forming and a variety of other applications. As a 3003 alloy, H14 aluminum sheets can be formed easily. Debossing or embossing an alloy of this temper can typically be done without cracking or straining the metal.

The H14 in this 3003 alloy designates its temper, and also means that it’s partially annealed and strain hardened. This makes this metal easy to form. Another type of 3003 H14 aluminum sheet is the diamond sheet, which consists of the same properties. This diamond-patterned sheet is slip-resistant and offers aesthetic appeal. It’s also lightweight, yet strong.

3003 aluminum coil Application:

Aluminium coil 3003 is an alloy with very good corrosion resistance and moderate strength. Excellent weldability, formability, with good machinability makes 3003 Aluminium coil, coil and tread coil is popular and economical choice in Appliance Components. Alloy 3003 can be cold worked to produce tempers with a higher strength but a lower ductility while not heat-treated or used in casting. It is commonly rolled and extruded as aluminium coil and foils which in different applications such as truck and trailer roofing, cooking utensils, pressure vessels, refrigerator panels, gasoline tanks, heat exchanger, furniture components.

The most common applications for the 3003 aluminum coil are for fuel tanks, sheet metal work and other types of projects that need a metal that is stronger than the 1100 series aluminum. In some cases, it is used for cooking utensils, refrigerator panels, gas lines, storage tanks, garage doors, builder’s hardware and awning slats.
