3系铝卷也叫防锈铝板，主要合金元素是锰。代表性品种为3003和3004铝板，比工业纯铝板强度高，成形性、焊接性、耐腐蚀性良好，由于不能强化热处理，工艺中往往采用冷加工来提高力学性能。其中3004的强度优于3003，主要状态为o、H12、H14、H16、H18、H19、H32、H34、H36、H38等，那么，下面一起了解下3系铝卷的特点及应用吧!

　　3 series aluminum coil, also known as rust proof aluminum plate, is mainly composed of manganese alloy element. The representative varieties are 3003 and 3004 aluminum plates, which have higher strength than industrial pure aluminum plates, good formability, weldability, and corrosion resistance. Due to the inability to strengthen heat treatment, cold processing is often used in the process to improve mechanical properties. Among them, 3004 has better strength than 3003, mainly in the states of o, H12, H14, H16, H18, H19, H32, H34, H36, H38, etc. So, let's learn about the characteristics and applications of 3 series aluminum coils together!

　　Characteristics of 3-series aluminum coils:

　　3系铝卷用量较多的是3003个品牌的镁铝合金，3003铝板加工方便，防锈良好，能在原铝表面涂上彩色油漆，使用寿命优于钢材。3003与5052相比价格便宜，焊接性也好。有的货车油箱材料厂家用3003H24铝板代替5052制作油箱内不需要受压的隔板，降低成本也不影响使用。3004合金强度高于3003，成形性更好，强度高，易于加工。成型氧化后能形成致密的氧化膜不仅是耐腐蚀氧化，而且具有良好的绝缘性，即降低了成品的总重，保证了良好的散热性能。

　　The most commonly used 3-series aluminum coils are 3003 brands of magnesium aluminum alloy. 3003 aluminum plates are easy to process, have good rust prevention, can be coated with colored paint on the surface of the original aluminum, and have a longer service life than steel. Compared to 5052, 3003 is cheaper and has better weldability. Some truck fuel tank material manufacturers use 3003H24 aluminum plate instead of 5052 to make pressure free partitions inside the fuel tank, reducing costs and not affecting usage. 3004 alloy has higher strength than 3003, better formability, high strength, and is easy to process. The formation of a dense oxide film after molding oxidation is not only corrosion-resistant, but also has good insulation properties, which reduces the total weight of the finished product and ensures good heat dissipation performance.

　　3 Series Aluminum Coil Usage:

　　3系铝卷适用于工业纯铝板应用领域及其他硬度要求更高的领域，常用于厨具、食物与化工储运、散热片、家电(如空调、冰箱、洗衣机等)等各种领域，是镁铝合金板中常见的系列。其中3004和3104铝带是目前生产罐体的主流材料。

　　3 series aluminum coils are suitable for industrial pure aluminum plate applications and other fields with higher hardness requirements. They are commonly used in various fields such as kitchenware, food and chemical storage and transportation, heat sinks, household appliances (such as air conditioners, refrigerators, washing machines, etc.), and are a common series of magnesium aluminum alloy plates. Among them, 3004 and 3104 aluminum strips are currently the mainstream materials for producing tank bodies.

　　3系铝卷又称铝锰合金，锰元素含量为1-1.5%，是一种应用广泛的防锈镁铝合金系列。3系镁铝合金强度高于纯镁铝合金，不能通过热处理强化性能，但经过冷加工(冷轧机轧制)和退火工艺处理后具有良好的可塑性，具有优良的耐蚀性和焊接性能，可以用于很多行业。例如，楼盘装饰行业、电子制造业、汽车制造业等

　　3 series aluminum coil, also known as aluminum manganese alloy, has a manganese content of 1-1.5% and is a widely used rust proof magnesium aluminum alloy series. The strength of 3-series magnesium aluminum alloy is higher than that of pure magnesium aluminum alloy, and its performance cannot be strengthened by heat treatment. However, after cold processing (cold rolling) and annealing process, it has good plasticity, excellent corrosion resistance and welding performance, and can be used in many industries. For example, the real estate decoration industry, electronic manufacturing industry, automobile manufacturing industry, etc

　　3系铝卷常用的主要品种有3003铝板、3004铝板、3104铝板、3005铝板、3105铝板等。其中用量较多的是3003个品牌的镁铝合金，3003铝板加工方便，防锈良好，原铝表面涂彩色油漆，可制作各种装饰幕墙板，室内用铝天花板拉板

　　The main varieties commonly used for 3-series aluminum coils include 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, 3105 aluminum plate, etc. Among them, 3003 brands of magnesium aluminum alloy are used in large quantities. The 3003 aluminum plate is easy to process, has good rust prevention, and the original aluminum surface is coated with colored paint. It can be used to make various decorative curtain wall panels and indoor aluminum ceiling panels

　　3003与5052相比价格便宜，焊接性也好。有的货车油箱材料厂家用3003H24铝板代替5052制作油箱内不需要受压的隔板，降低成本也不影响使用。3004合金强度高于3003，成型性更好，可作为全铝罐体、化工液体的生产和储存装置。3104合金和3004合金成分极为接近，强度高，容易加工。电视机制造业多采用3104-O状态板材制作电视机液晶背板，冲压凸包，添加电子元器件。成型氧化后能形成致密的氧化膜不仅是耐腐蚀氧化，还有良好的绝缘性，即降低了产品的总重量，保证了良好的散热性能。3005合金多用于较高端色彩鲜艳的铝辊涂层，由建材行业生产，也可制作屋面隔断、活动板房等，空调、冰箱等散热片，内部零件等。3105合金主要可用于瓶盖、瓶盖等冲压件的制作。

　　Compared to 5052, 3003 is cheaper and has better weldability. Some truck fuel tank material manufacturers use 3003H24 aluminum plate instead of 5052 to make pressure free partitions inside the fuel tank, reducing costs and not affecting usage. The strength of 3004 alloy is higher than 3003, and its formability is better. It can be used as a production and storage device for all aluminum tanks and chemical liquids. 3104 alloy and 3004 alloy have very similar compositions, high strength, and are easy to process. The TV manufacturing industry often uses 3104-O state board to make TV LCD backboards, stamping convex shells, and adding electronic components. The formation of a dense oxide film after molding oxidation is not only resistant to corrosion oxidation, but also has good insulation properties, which reduces the total weight of the product and ensures good heat dissipation performance. 3005 alloy is commonly used for high-end and brightly colored aluminum roller coatings. It is produced by the building materials industry and can also be used to make roof partitions, prefabricated houses, air conditioners, refrigerators, and other heat sinks, as well as internal components. 3105 alloy is mainly used for the production of stamped parts such as bottle caps and bottle caps.
