You will learn the complete info about aluminum coils and how to choose it when importing from China.
What is Aluminum coils
Aluminum coil (aluminum coil) is a metal product, which is mainly formed by rolling and bending through a casting and rolling mill.
Its raw materials mainly include pure aluminum, hot-rolled aluminum coil or aluminum alloy cast-rolled aluminum coil.
Compared with aluminum plates and aluminum strips, aluminum coils are softer and more plastic, so they are more commonly used in situations where bending is required.
Aluminum coils applications
Aluminum coils is popular in construction, packaging, electronics, home appliances and other fields.
Construction field: You can use Aluminum coils to reduce the weight of buildings and improve the safety performance of buildings. At the same time, Aluminum coils can also play a role in beautification and energy saving.
Packaging field: You can also use Aluminum coils in food and beverage packaging because aluminum coils have excellent properties such as moisture resistance and oxidation resistance, which can effectively protect the quality of food and beverages and extend the shelf life.
Aluminum coils thickness
Aluminum coils are usually delivered in roll form, weighing about 2-3 tons, which is easy to load and unload. Its thickness ranges from 0.15 mm to 15 mm, and the commonly used thickness is between 0.2 mm and 1 mm.
The thickness of aluminum coils usually ranges from 0.10mm to 15mm, and the commonly used thickness range is 0.2mm to 1mm. The specific thickness specifications are as follows:
Anti-corrosion and anti-rust insulation aluminum coils: thickness of 0.3mm to 3.0mm, width of 600mm to 2000mm.
Special aluminum coils for power plants: thickness of 0.5mm, 0.6mm, 0.75mm, 0.8mm, width of 600mm to 1200mm.
Color-coated aluminum coils/embossed aluminum coils: thickness of 0.02mm to 1.2mm, width of 600mm to 1370mm.
Insulation aluminum coils: commonly used thickness of 0.3mm to 1.0mm, width of 1000mm.
In addition, aluminum coils of different materials also have their specific application scenarios and thickness ranges. For example, the thickness range of pure aluminum plates (such as 1050, 1060, 1100, etc.) is 0.1mm to 20mm, and the width is 800mm to 2200mm; the thickness range of alloy aluminum plates (such as 2A21, 3003, 5052, etc.) is 0.5mm to 260mm, and the width is 800mm to 2800mm.
How to choose Aluminum coils
1. Clarify the use requirements
Purpose and performance requirements:
First, the specific use of aluminum coils should be clarified, such as building exterior wall decoration, furniture manufacturing, automobile manufacturing, pipe insulation, etc. Different uses have different performance requirements for aluminum coils, such as corrosion resistance, light weight and high strength, easy processing, etc.
Determine the alloy type of aluminum coil according to actual needs, such as common 1060, 3003, 5052 and other alloy aluminum coils, each of which has different physical and chemical properties.
Specifications and dimensions:
Determine the required specifications and dimensions of aluminum coils, including width, length, thickness, etc. This helps to ensure that the purchased aluminum coils can be directly applied to actual production and reduce subsequent processing costs.
2. Pay attention to the quality of aluminum coils
Material and alloy composition:
Learn the material and alloy composition of the aluminum coil in detail to ensure that it meets the use requirements. Aluminum coils with different alloy compositions differ in hardness, strength, corrosion resistance, etc.
You can obtain relevant information by checking the product manual, quality inspection report or consulting the supplier.
Surface quality:
Check whether the surface of the aluminum coil is flat, without scratches, oxidation spots and other defects. Good surface quality is not only beautiful, but also ensures the smooth progress of subsequent processing and use.
For color-coated aluminum coils, it is also necessary to check whether the coating is uniform, consistent in color, and free of bubbles and peeling.
Physical properties:
Understand the physical performance indicators of aluminum coils such as tensile strength, yield strength, and elongation. These indicators are one of the important criteria for measuring the quality of aluminum coils.
You can obtain this information by consulting relevant standards or asking suppliers for test reports.
3. Choose a reliable supplier
Reputation and reputation:
Choose suppliers with good reputation and reputation, who are usually able to provide more reliable products and services. The reputation of suppliers can be evaluated by searching the Internet and referring to recommendations in the same industry.
Production capacity and technical level:
Understand the production capacity and technical level of suppliers, including production equipment, process flow, quality control, etc. This helps to determine whether the supplier is capable of producing aluminum coil products that meet the requirements.
After-sales service:
Pay attention to the supplier's after-sales service policy, including return and exchange policy, technical support, etc. Good after-sales service can ensure that problems encountered during use can be solved promptly and effectively.
4. Price and cost performance
Market price research:
Conduct market price research before purchasing to understand the current market price range of aluminum coils and the price differences of different brands and specifications. This will help to obtain a more reasonable price during negotiations.
Cost performance evaluation:
Make a trade-off between price and quality and choose aluminum coil products with high cost performance. Don't blindly pursue low prices and ignore quality factors. At the same time, you should also pay attention to avoid being deceived by high-priced and low-quality products.
5. Other matters needing attention
Purchase quantity and batch:
Determine the purchase quantity and batch according to actual needs. Large-volume purchases usually get lower prices and better service guarantees; but also pay attention to avoid inventory backlogs and excessive capital occupation.
Logistics and transportation:
Reasonably arrange logistics and transportation methods to ensure that aluminum coils can be delivered to the destination safely and promptly. At the same time, pay attention to controlling logistics costs and avoid unnecessary expenses.
Contract and payment:
Before signing a contract with a supplier, read the terms of the contract carefully and confirm that they are correct before signing and stamping. At the same time, pay attention to details such as payment methods and deadlines to ensure that the rights and interests of both parties are protected.
