Advantages of Chalco brazed composite aluminum sheet, brazed deep-drawn sheet
Alcoa brazed composite aluminum plate and brazed deep-drawn plate are both lightweight and high-strength aluminum alloy materials made by brazing process, and they have the following advantages:
Light weight: compared with steel materials, composite aluminum plates and brazed deep-drawn plates are less dense and lighter in weight, which can greatly reduce the weight of the whole product and improve the fuel efficiency and operational efficiency of the product.
High strength: due to the brazing process used for these aluminum plates, a strong connection is formed between the aluminum alloy layers, which improves the strength and durability of the entire aluminum plate.
Excellent corrosion resistance: the aluminum alloy material has excellent corrosion resistance and can maintain stable performance in harsh environments for a long time.
Simple manufacturing process: the brazing process does not require a large amount of equipment and large machines and can be used for mass production, thus reducing production costs.
Good plasticity: aluminum has good plasticity and can be made into various shapes, which can be widely used in different products and industries.
Environmental protection: aluminum has good recyclability and will not cause pollution to the environment, which meets the requirements of environmental protection.
