1100 metal pure aluminum sheet plate belongs to 1000 series aluminum sheet, which is industrial pure aluminum with an aluminum content (mass fraction) of 99.00%, which cannot be strengthened by heat treatment. It has high corrosion resistance, electrical conductivity and thermal conductivity, its density is small, plasticity is good, various aluminum materials can be produced by pressure processing, but the strength is low. Other process performance is basically the same as 1050A. 1100 aluminum is usually used to require good forming processing performance, high corrosion resistance, and does not require high strength, such as food and chemical handling and storage equipment, sheet metal products, hollow hardware processed with drawn goods, and welded combination keys , Reflectors, nameplates, etc.

1100 aluminum strip belongs to pure aluminum plate series, its strength is relatively low, and it has excellent ductility, formability, weldability and corrosion resistance; after anodizing, it can further improve the corrosion resistance and at the same time obtain a beautiful surface; but can not be strengthened by heat treatment .

The pure aluminum sheet series determines the minimum aluminum content of this series according to the last two Arabic numerals. For example, the last two Arabic numerals of the 1100 series are 00. According to the international brand naming principle, the aluminum content must reach 99.00% or more as a qualified product. my country’s aluminum alloy technical standard (GB/T3880-2012) also clearly stipulates that the aluminum content of 1100 reaches 99.0%.

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

Features of 1100 flat aluminum plates

1. Excellent corrosion resistance. 1100 aluminum sheet has good resistance to atmospheric (including industrial atmospheric and Marine vapor) corrosion and water corrosion.In addition, it can resist the corrosion of most acids and organics.

2..Good ductility and molding.1100 aluminum sheet can produce various aluminum materials through pressure processing, which can adapt to the larger speed of most machine tools for turning, milling, boring, planing and other mechanical processing.Moreover, the good molding of1100 aluminum sheet enables it to be rolled into sheet and foil, or pulled into pipes and wires, etc.

3.No low-temperature brittleness.1100 aluminum sheetbelow0℃,as the temperature decreases, its strength and molding will not reduce, but increase.

4. The1100 aluminum sheetstrength is low, it cannot be strengthened by heat treatment, and the cutting property is poor.

Applications of 1100 mill finish aluminium sheet

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, aluminum gusset plate, heat exchangers, cold working aluminum plate for chemical, expanded metal product etc.

1100 aluminum sheet is widely used in various fields from cooking utensils to industrial equipment, such as heat sinks, caps, printing sheets, heat exchanger components, it can also be used as deep-draw stamping products.

Decoration: making perforated sheet etc

Building materials: ACP ( aluminum composite panel ), curtain wall, thermal insulation aluminum sheet etc

Kitchen utensils, high pressure cooker etc.
