Production Process of 3003 Aluminum Alloy

2025-02-13 16:02:34

3003 aluminum alloy is a rust-proof aluminum coil/aluminum plate. Due to the addition of manganese, the manganese content is 1.0-1.8% and the aluminum content is above 98.00%. 3003 aluminum coil has the characteristics of low price, stable quality and mature technology. It has a wide market application, such as automobile lining, thermal insulation aluminum coil, road signs, square pressed tiles or stamping processing, etc.

Introduction to the production process of 3003 aluminum alloy

3003 aluminum coil is an AL-Mn series alloy product, which is the most widely used product in the 3 series products.

The strength of 3003 aluminum coil is about 10% higher than that of 1 series products such as 1060 aluminum coil and 1100 aluminum coil, and the Vickers hardness test data is about 10 higher.

3003 aluminum coil has high corrosion resistance and is generally suitable for processing products with high requirements for formability.

3003 aluminum coil is very friendly to parts with high corrosion resistance requirements. For example, ship screws, ship panels, radiator low plates and heat sinks, etc. It has extremely high application value in kitchenware applications, transportation applications, industrial product storage and processing applications, etc.

Annealing process of 3003 aluminum alloy

3003-H24 aluminum coil annealing process: the temperature in the annealing furnace is raised to about 390-430 degrees, and the temperature is maintained for about 12 hours, then the temperature in the furnace is lowered to below 300 degrees based on 30-50 degrees, and the temperature is placed outside to cool and then opened on the machine.
3003-H14 aluminum coil annealing process: the temperature in the annealing furnace is raised to about 390-430 degrees, and the temperature is maintained for about 11 hours, and the temperature in the furnace is lowered to below 300 degrees based on 30-50 degrees. The aluminum plate is rolled again, and then it is placed outside to cool and then opened on the machine.
3003-H18 aluminum coil non-annealing process: cold rolling mill processing directly into finished products
3003-O aluminum coil annealing process: the temperature in the annealing furnace is raised to about 390-430 degrees, and the temperature is maintained for about 20 hours. The temperature in the furnace is lowered to below 300 degrees at 30-50 degrees. The aluminum plate is rolled again, and then it is cooled outside and flattened on the machine.

Application of 3003 aluminum alloy

3003 aluminum coil cannot strengthen the surface hardness of aluminum plate through heat treatment, so in general, 3003 aluminum coil is mainly processed by cold rolling, that is, aluminum coil annealing process, such as common aluminum coil 3003-H24 state, aluminum coil 3003-H14 state, etc. 3003 aluminum coil is mainly used in: curtain walls, traffic signs, sealed storage, refrigerator lining, aircraft and ships, etc.
