Why is recycled aluminum so hot? What is the difference between 3004 aluminum plate and 3003?

3004 aluminum plate: 3004 series aluminum plate also belongs to a series of aluminum manganese alloy, higher strength than 3003, excellent formability, good corrosion resistance, requiring higher strength parts than 3003 alloy.

3004 is AL-Mn alloy, is the most widely used a kind of anti-rust aluminum, the strength of this alloy is not high (slightly higher than industrial pure aluminum), can not be strengthened by heat treatment, so the use of cold processing method to improve its mechanical properties: In the annealing state has a high plasticity, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, poor machinability. It is mainly used for low-load parts that require high plasticity and good weldability, working in liquid or gas media, such as mailboxes, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made with deep drawing: wire is used for rivets

3004 aluminum sheet formability, solubility, corrosion resistance are good. For processing parts that need to have good formability, high corrosion resistance and good weldability, or require these properties and need to have higher strength than 1XXX series alloy, such as kitchenware, food and chemical products processing and storage devices, tanks and tanks for transporting liquid products, All kinds of pressure vessels and pipe general utensils, heat sinks, cosmetic plates, copier rollers, Marine materials processed with thin sheets

3004 Aluminum plate belt is mainly used in chemical products production and storage devices, sheet workpieces, building materials, construction baffles, cable pipelines, sewers, various lighting parts, beverage cans, wave boards, building materials, colored aluminum plates, lamp heads.

... ...

3003 Aluminum plate: 3003 series aluminum plate is a common product of aluminum manganese alloy series. Due to the manganese alloy element, this product has excellent anti-rust characteristics, and is also known as anti-rust aluminum plate.

The strength is about 10% higher than 1100, and the formability, solubility and corrosion resistance are good. For processing parts that need to have good formability, high corrosion resistance and good weldability, or require these properties and need to have higher strength than 1XXX series alloy, such as kitchenware, food and chemical products processing and storage devices, tanks and tanks for transporting liquid products, All kinds of pressure vessels and pipe general utensils, heat sinks, cosmetic plates, copier rollers, Marine materials processed with thin sheets.

The difference between the two is that the scope of application is not applicable. In addition, there are many reasons for recycled aluminum fire, the most important is

1. Environmental awareness is enhanced, and the improvement of technology makes aluminum can be reused

2. The cost of raw aluminum is high, and the cost of raw materials has risen sharply due to the epidemic, inflation and foreign trade resistance
