1100 aluminum sheet plate overview

1100 aluminum sheet plate belongs to 1xxx series aluminum sheet, which  is one of the softest aluminum alloys, so it is not used for high strength or high pressure applications. Although pure aluminum is usually cold-worked, it can also be hot-worked, but it is more common that aluminum is formed through spinning, stamping, and drawing processes that do not require the use of high heat. These processes produce aluminum profiles in the form of foils, plates, round bars, sheets, strips and wires. Aluminum 1100 can also be welded; resistance welding is possible, but it can be difficult and usually requires the attention of a skilled welder. Aluminum 1100 is just one of several common aluminum alloys. It is soft, low-strength, and the smallest aluminum at 99% is commercial pure aluminum. Copper, iron, magnesium, manganese, silicon, titanium, vanadium and zinc constitute the remaining elements. It cannot be hardened by heat treatment and is very formable.

1100 aluminum alloy is ordinary industrial pure aluminum with 99.0% aluminum content. It cannot be strengthened by heat treatment; the strength is low, but it has good ductility. Formability, weldability and corrosion resistance; after anodic oxidation, the corrosion resistance can be further improved while obtaining a beautiful surface.

1100 aluminum sheet is a typical industrial pure aluminium (99.00% of aluminum), and cannot be heat treated. It has some features such as high anti-corrosion, great electrical conductivity and thermal conductivity, low density, plasticity is pretty good that can produce some aluminium profiles by pressure processing, but the strength of 1100 aluminium alloy is low. The other properties of 1100 aluminium alloy are basically the same with the 1050A aluminium alloy.

1100 aluminum sheet is the most commercially pure alloy of all the aluminium grades. 1100 aluminium coil and 1100 aluminium sheet are both available for various applications including chemical storage and processing equipemtn. Benefits of 1100 aluminium coil & sheet include a 99% or greater content of aluminium compared to other grades of aluminium. 1100 is a low strength aluminium alloy with excellent corrosion resistance. This grade is best used for welding, brazing and soldering but has poor machinability. 1100 aluminium has great finishing capabilities so it is a great choice for decorative purposes.

Applications of 1100 aluminium plain sheets

1100 aluminum sheet is mostly used for some parts which require good forming and processing properties, high anti-corrosion, but low strength, such as video, the transportation and storage equipments of chemical products, metal sheet products, the processing of drawing spinning hollow goods, welding key combination, reflector and nameplat, etc. 1100 aluminum sheet is widely used in various fields from cooking utensils to industrial equipment, such as heat sinks, caps, printing sheets, building materials, heat exchanger components, it can also be used as deep-draw stamping products.

Cold rolled is the most commonly used forming method for aluminum 1100. A cold metal working process is any metal forming or forming process performed at or near room temperature. Aluminum 1100 can be processed into many different products, including chemical equipment, railroad tank cars, shark fins, dials, nameplates, cookware, rivets, reflectors, and metal plates. The plumbing and lighting industries also use aluminum 1100, as do many other industries.
