Aluminum plate VS aluminum alloy plate?
Many people mistakenly believe that aluminum plate is the abbreviation of aluminum alloy plate. In fact, aluminum plate is made of pure aluminum, and aluminum alloy plate is made of aluminum alloys with different compositions. Aluminum and aluminum alloy are essentially different in terms of alloy composition and use.
First, Alloy composition
Aluminum is a metal with active chemical properties. It is silvery white and widely found in nature. It is very light (ρ=2.7g/cm³) and has very good thermal and electrical conductivity. Pure aluminum is very soft and has good plasticity. It can be processed into various aluminum plates, aluminum materials, aluminum bars and other materials.
Aluminum Plate VS Aluminum Alloy Plate
Aluminum plate: Aluminum plate is a plate made of aluminum. It can be divided into pure aluminum plate, alloy aluminum plate, composite aluminum plate and aluminum-clad aluminum plate according to the alloy composition. It can also be divided into conventional plate, medium and thick plate, thick plate and thin plate according to size. Generally speaking, aluminum plate refers to pure aluminum plate, which is 1 series.
Aluminum alloy plate: Aluminum alloy plate is an aluminum profile made of aluminum as the main raw material, with copper, magnesium, zinc and other metals added. According to the alloy composition, aluminum alloy plate can be divided into 2-7 series, as shown in the table below:
| Series | Composition | Content | Representative Products |
| 1000 series | Pure aluminum plate | Aluminum content 99.9% | 1060 |
| 2000 series | Aluminum copper alloy plate | Copper content 3-5% | 2024 |
| 3000 series | Aluminum manganese alloy plate | Manganese content 1-1.5% | 3003 |
| 4000 series | Aluminum Silicon Alloy Plate | Silicon content 4.5-6% | 4A01 |
| 5000 series | Aluminum-magnesium alloy plate | Magnesium content 3-5% | 5052、5083 |
| 6000 series | Aluminum-magnesium-silicon alloy plate | Silicon content 0.2-0.6%
Magnesium content 0.49-0.9% |
6061 |
| 7000 series | Aluminum-zinc alloy sheet | Zinc content 1% | 7075 |
Second, Application fields
Due to different alloy composition, aluminum plates and aluminum alloy plates have different characteristics and their application ranges are very different. Aluminum plates are mainly used for household appliances, mold manufacturing, ship plates, etc. Aluminum alloy plates are mainly used for industrial profiles and are widely used in aerospace, rail transportation, and electronic appliances. The specific applications are as follows:
Applications of aluminum sheet plate
| Series | Application Areas |
| 1000 series | Used in various modern conventional industrial production, such as aerospace industry, automobile manufacturing, mold manufacturing, household appliances, chemical pipelines and construction industry. |
| 2000 series | It has high strength and good heat resistance. It is not commonly used in conventional industries. It is an aviation aluminum material. The alloy represented by 2017 is stronger than 7075 and is often used in truck wheels, rivets, aircraft propellers, etc. |
| 3000 series | Aluminum plates are used in refrigerators, air conditioners, car bottoms and other parts because of their good anti-rust properties and low price. |
| 4000 series | Building materials, mechanical parts, forged aluminum, low melting point, good heat and corrosion resistance. |
| 5000 series | It has low density and high tensile strength, and is widely used in conventional industries in my country, such as transportation vehicles, ship sheet metal parts, aircraft fuel tanks, etc. |
| 6000 series | Represented by 6061-T6 (solid solution heat treatment), it combines the advantages of 4 series and 5 series aluminum alloy plates and has good processing performance. It is used in various industrial structural parts, trucks, trams, precision instruments, aircraft joints and low-pressure weapons. |
| 7000 series | It has ultra-high strength and hardness, strong wear resistance, and is a high-end aviation aluminum material. The 7075 aluminum material is mainly used in aircraft manufacturing, such as stringers and bulkheads, and my country mainly relies on imports. |
