Production process of Chalco aluminum alloy 2024 (UNS A92024) extrusion
At present, the production process of aviation aluminum profiles mainly includes casting, extrusion and rolling.
Melting and casting is the method of heating the aluminum material to a liquid state and cooling it through a mold;
Extrusion is to extrude the aluminum material into profiles of various cross-sectional shapes;
Rolling is to pass the aluminum material through multiple passes of pressure. It is tapered and formed into profiles of the desired shape.
When purchasing 2024 automotive aluminum profiles, you need to pay attention to the following items
Material certification
When selecting suppliers, suppliers with qualifications and experience should be given priority, and qualified material certification certificates should be required at the same time.
The material certification certificate should include information such as the chemical composition, mechanical properties, processing technology and surface treatment of the material to ensure that the purchased 2024 aluminum profiles meet the corresponding standards and requirements.
Specification and size
According to the required specific use and design requirements, select the appropriate 2024 aluminum profile specification and size. Pay attention to the performance and price differences between different specifications and sizes, and make choices and trade-offs according to actual needs.
Surface treatment
The surface treatment of 2024 aluminum profiles includes oxidation, anodic oxidation, electrophoretic coating, sandblasting and other methods.
Choose the appropriate surface treatment method according to the specific requirements to improve the corrosion resistance, wear resistance and aesthetics of the 2024 aluminum profile.
Supply cycle and delivery method
When negotiating with suppliers, details such as supply cycle and delivery method need to be clarified. Ensure that the purchased 2024 aluminum profiles can be supplied in a timely manner.
At the same time, suppliers are required to provide reasonable transportation and delivery methods to ensure that the goods arrive at their destination safely and in time.
Price and after-sales service
Price is a factor that cannot be ignored in the procurement process. The price and after-sales service of different suppliers should be evaluated and compared, and the cost-effective supplier should be selected for cooperation.
At the same time, establish a good cooperative relationship with suppliers to obtain better service and support in future cooperation.
