3003 alloy metal aluminum sheet plate is approximately 20% stronger than 1100 series aluminium. 3003 alloy is readily formed by either conventional cold working or hot working. We offers high quality 3003 flat aluminium sheet plate and tread plate 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 sheet plate and 3003 aluminum tread plate offers increased rigidity in the material as well as hiding fingerprints and dents. The tempers commonly used include H14, H16 and H18, while others are also available by customers’ demands.

3003 aluminum alloy is AL-Mn series alloy, which is the most widely used rust-proof 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 method is used to improve its mechanics Performance: high plasticity in the annealed state, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, and poor machinability. Uses are mainly used for low load parts that require high plasticity and good weldability, working in liquid or gaseous media, such as fuel tanks, gasoline or lubricant pipes, various liquid containers, and other small load parts made by deep drawing. The wire is used to make rivets.

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

Corrosion resistance: 3003 aluminum alloy has good corrosion resistance, which is close to that of industrial pure aluminum. It has good corrosion resistance to atmosphere, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt solution, etc., and also in dilute acid. A kind of
In the cold deformation state, 3003 aluminum alloy has the tendency of exfoliation corrosion. The larger the deformation is, the more serious the exfoliation is. Because of the uneven color after anodizing, anodizing is generally not carried out.

3003 alloy aluminum sheet features

1. Corrosion Resistance.3003 aluminum sheet has good corrosion resistance, which is close to the corrosion resistance of industrial pure aluminum. It can effectively resist the corrosion of atmosphere, fresh water, sea water, food, organic acids, gasoline, neutral inorganic salt solution, and dilute acids.

2. High Plasticity. In the annealed temper, the plasticity of the3003 aluminum sheet is very high. In the case of semi-cold work hardening, its plasticity is still good, and its plasticity is low when it is cold worked. Good weldability and poor machinability.

3. Weak Resistance to Peeling Corrosion. In the cold deformed state, the3003 aluminum sheet has a tendency to peel and corrode. The larger the deformation is, the more severe the peeling is. Because the color is not uniform after anodizing, anodizing is generally not performed.

Usages of 3003 Aluminum Sheet
Typical uses of3003 aluminum sheet: heat sinks, radiators, power battery enclosures, automotive heat shields, fuel tanks, water tanks, automotive skid plates, battery explosion-proof valves, battery covers, automotive interiors, signs, cans, medical equipment, etc.

Typical use of Ultra-wide3003 aluminum sheet: bus skins, silos, antenna pan materials, wide curtain wall panels, wide roof panels, etc.

3003 alloy aluminum sheet application

3003 mill finish aluminum sheet plate is an alloy with very good corrosion resistance and moderate strength. Excellent weldability, formability, with good machinability makes 3003 Aluminium Sheet, coil and tread plate 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 sheet and foils which in different applications such as truck and trailer roofing, cooking utensils, pressure vessels, refrigerator panels, gasoline tanks, heat exchanger, furniture components.

3003 plain aluminum sheet plate is not heat treatable and develops strengthening from cold working only. Commonly used in chemical equipment, ductwork, and in general sheet metal work. Aluminium 3003 is also used in the manufacture of cooking utensils, pressure vessels, builder’s hardware, eyelet stock, ice cube trays, garage doors, awning slats, refrigerator panels, gas lines, gasoline tanks, heat exchangers, drawn and spun parts, and storage tanks.
