What is 1100 aluminum sheet ?

1100 aluminum plate is industrial pure aluminum, the aluminum content (mass fraction) is 99.00%, and it cannot be strengthened by heat treatment. It belongs to the 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 obtain a beautiful surface; but it cannot be strengthened by heat treatment.

What is 3003 aluminum sheet?

3003 series aluminum plate is a common product of aluminum-manganese alloy series. Due to the manganese alloy element, this product has excellent anti-rust properties, also known as anti-rust aluminum plate.

What are the characteristics of 1100 aluminum plate and 3003 aluminum plate?

1100 aluminum plate and strip belong to the pure aluminum plate series, its strength is relatively low, and it has excellent ductility, formability, weldability and corrosion resistance; after anodization, the corrosion resistance can be further improved, and a beautiful surface can be obtained; but it cannot be strengthened by heat treatment .

3003 is an AL-Mn alloy, which is the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than that of industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: It has high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Mainly used for low-load parts that require high plasticity and good weldability, working in liquid or gas media, such as fuel tanks, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing: Wire is used to make rivets.

Scope of application

1100 aluminum plate is generally used in utensils, heat sinks, bottle caps, printing boards, building materials, heat exchanger components, and can also be used as deep-drawing products. It is widely used in various fields from cookware to industrial equipment.

3003 aluminum plate is often used in ships, ships, vehicle materials, automobile and aircraft plate welding parts, pressure vessels requiring strict fire protection, refrigeration equipment, TV towers, drilling equipment, transportation equipment, missile components, armor, etc.

Summary: 1100 aluminum sheet is pure aluminum, the content of aluminum is as high as 99%, soft, good thermal conductivity, electrical conductivity and corrosion resistance, 3003 aluminum is aluminum-manganese alloy, the hardness is stronger than 1100 aluminum, the weldability is better, and the price is higher than 1100, Therefore, when choosing these two alloys, if the product is only used in decorative parts, it is recommended to choose 1100 aluminum plate, and some parts that are easily exposed or impacted by external forces can use 3003 aluminum plate, so that the cost performance will be the highest.
