Aluminum coil manufacturers explain the advantages and disadvantages of 3-series aluminum coil aluminum plates

3 SeriesAluminum plate manufacturer--Alloy aluminum plate

The 3-series aluminum plate is currently a widely used first series aluminum plate in China. The main alloying element of the 3-series aluminum plate is manganese, hence it is also known as aluminum manganese alloy. At present, the commonly used 3-series aluminum plate grades in China include: 3003, 3004, 3005, 3A21, etc.

Characteristics of 3-series aluminum plates

1. The biggest feature of the 3 series aluminum plate is its excellent rust and corrosion resistance. Due to the addition of manganese, the 3-series aluminum plate has higher corrosion resistance than the 1-series aluminum plate, and has good corrosion resistance to atmospheric, fresh water, seawater, food, organic acids, gasoline, neutral inorganic saline solutions, etc. It also has good corrosion resistance in dilute acids, making it suitable for many special environments.

2. The hardness of 3-series aluminum plate is about 10% -20% higher than that of pure aluminum plate, which can be cold worked to improve strength. It has good formability, solubility, and corrosion resistance under room temperature conditions, and excellent welding performance.

Disadvantages of 3-series aluminum plates

In the cold deformation state, the 3-series aluminum plate tends to peel off and corrode, and the greater the deformation, the more severe the peeling. Due to uneven color after anodizing, anodizing treatment is generally not carried out.

Usage of 3-series aluminum plates

Analysis characteristics and application scope of service providers for 3-series aluminum plate manufacturers:

3003 is an AL-Mn alloy, which is the most widely used type of rust resistant aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: it has high plasticity in the annealing state, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability. 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 ducts, various liquid containers, and other low load parts made by deep drawing: Wire is used for rivets 3003 aluminum plateGood formability, solubility, and corrosion resistance. Used for processing parts and components that require good formability, high corrosion resistance, and weldability, or work that requires both these properties and higher strength than 1XXX series alloys, such as kitchen utensils, food and chemical product processing and storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipelines processed from thin plates, general utensils, heat sinks, cosmetic boards, photocopier rollers, and ship materials.

Analysis of the performance of 3003 aluminum plate by a service provider from a 3-series aluminum plate manufacturer

Corrosion resistance: 3003 aluminum alloy has excellent corrosion resistance, close to the corrosion resistance of industrial pure aluminum. It has good corrosion resistance to atmosphere, fresh water, seawater, food, organic acids, gasoline, neutral inorganic saline solutions, etc. It also has good corrosion resistance in dilute acids.

In the cold deformation state, 3003 aluminum alloy has a tendency for peeling corrosion, and the greater the deformation, the more severe the peeling. Due to uneven color after anodizing, anodizing treatment is generally not carried out
