Aluminum alloy is a kind of non-ferrous metal structural material widely used in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the research on the weldability of aluminum alloys has also deepened. At present, aluminum alloys are the most widely used alloys.
 
The difference between aluminum alloy and aluminum plate:
 
1. Different alloy composition: aluminum plate is a plate made of aluminum. According to the alloy composition, it can be divided into pure aluminum plate, alloy aluminum plate, composite aluminum plate and aluminum plate. According to the size, it can be divided into ordinary plate, medium plate, thick plate and thin plate, and aluminum plate. Refers to pure aluminum plate. Aluminum alloy plate is an aluminum profile made of aluminum as the main raw material, adding copper, magnesium, zinc and other metals.
 
2. Different application fields: Aluminum plates are mainly used in household appliances, mold manufacturing, ship plates, etc. Aluminum alloy plates are mainly used in industrial profiles, aerospace, rail transit and electronic appliances.
 
3. Different concepts: Aluminum alloy is a non-ferrous metal structural material widely used in industry. Aluminum plate is a rectangular plate rolled from aluminum ingots.
Aluminum alloy processing
Material properties of aluminum alloy:
 
Aluminum alloy has low density, but high strength, close to or surpassing high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry, second only to steel. Some aluminum alloys can obtain good mechanical properties, physical properties and corrosion resistance through heat treatment.
 
Hard aluminum alloy AI-Cu-Mg system generally contains a small amount of Mn, which can be strengthened by heat treatment. It is characterized by high hardness, but poor plasticity. Super hard aluminum belongs to the Al-Cu-Mg-Zn system, which can be strengthened by heat treatment. It is an aluminum alloy with high strength at room temperature, but it has poor corrosion resistance and fast softening at high temperature.
 
Forged aluminum alloys are mainly Al-Zn-Mg-Si alloys. There are many types of added elements, but the content is small, so they have excellent thermoplasticity and are suitable for forging, so they are also called forged aluminum alloys.
 
Aluminum alloy is a general term for alloys produced by dissolving aluminum and other metals. A certain proportion of other metals are added to the molten aluminum to improve the strength of the aluminum, and the weight change is small. For example, aluminum-magnesium alloy, aluminum-titanium alloy, aluminum-lithium-magnesium alloy, aluminum-magnesium-manganese alloy, etc.
