What is 1100 series aluminum coil?

1100 aluminum coil is the most commercially pure alloy of all the aluminum grades. 1100 aluminum coil is available for various applications including chemical storage and processing equipemtn. Benefits of 1100 aluminum coil  include a 99% or greater content of aluminum compared to other grades of aluminum. 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 coil has great finishing capabilities so it is a great choice for decorative purposes.

How strong is 1100 aluminum coil?

1100 is a typical industrial pure aluminium (99.00% of aluminium), 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.

Application of 1100 aluminium plate rolls

Over 99% content of aluminum, 1100 aluminum trim coil is soft and has low strength, so it is not suitable for high-strength, high-pressure or hardness applications, instead, it is used for chemical equipment, decorative trim and heat exchangers. 1100 aluminum coil has superior correction resistance, formability, conductivity and high weld-ability, so it is best used for welding, brazing and soldering but has poor machine-ability. For the features above,  1100 aluminum coil are both available for various applications, including chemical storage and processing equipment. 1100 aluminum coil is nonmagnetic and non-heat treatable, besides, it has great finishing capacity, so it can be a wise choice for decorative applications.

1100 aluminium alloy 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 coil products, the processing of drawing spinning hollow goods, welding key combination, reflector and nameplat, etc. 1100 aluminium coil is widely used in various fields from cooking utensils to industrial equipment, such as heat sinks, caps, printing coils, building materials, heat exchanger components, it can also be used as deep-draw stamping products.

Kitchen utensils, building materials, heat exchangers, etc.
