Description of aluminum alloy

Primary aluminum is collectively referred to as electrolytic aluminum in the market supply, and it is the raw material for the production of aluminum and aluminum alloy materials. Aluminum is a metal with low strength and good plasticity. In addition to the application of some pure aluminum, in order to improve the strength or comprehensive performance, it is made into an alloy. Adding an alloying element to aluminum can change its structure and properties, making it suitable for various processing materials or casting parts. Alloying elements that are often added are copper, magnesium, zinc, and silicon.

Aluminum alloy grade naming principle

• 1. The trademark of the international four-digit number system can be directly quoted.
• 2. Deformed aluminum and aluminum alloys that are not named as international four-digit number system grades should be named with four-character grades (but experimental aluminum and aluminum alloy colors use the prefix X plus four-character grades).

Classification and application of aluminum alloy

Aluminum alloys are alloys made by mixing aluminum with other metal elements and are commonly used in various industrial fields, including aerospace, automobile manufacturing, construction, electronics, food packaging, and more.

The following are some common aluminum alloy grades and their characteristics:

• 1000 series aluminum alloy: Contains more than 99% aluminum, and the common grades are 1050, 1060, 1100; it has good machinability, electrical conductivity and corrosion resistance. It is often used in the manufacture of food containers, wires and cables, die-casting parts, etc.
• 2000 series aluminum alloy: Contains copper and has high strength and corrosion resistance. Common grades are 2011, 2014, and 2024; they are often used in the manufacture of aerospace components, ships, automobile and bicycle components, etc.
• 3000 series aluminum alloy: contains manganese, has good strength and corrosion resistance, and is easy to weld and process. Common grades are 3003, 3004, 3104, 3105; often used in the manufacture of building materials, ships, aircraft wing spars, etc.
• 4000 series aluminum alloy: contains silicon and has high strength, hardness and wear resistance. Common grades are 4032, 4043, 4047; often used in the manufacture of aircraft parts, automotive brake systems, etc.
• 5000 series aluminum alloy: containing magnesium, it has good plasticity, strength and corrosion resistance. Common grades are 5005, 5050, 5052, 5083, 5454, 5754; commonly used in the manufacture of aerospace vehicles, building materials, bicycle frames, etc.
• 6000 series aluminum alloy: contains magnesium and silicon, has high strength and corrosion resistance, and is easy to weld and process. Common grades are 6060, 6061, 6063, 6082; commonly used in the manufacture of aircraft parts, auto parts, ship structures, etc.
• 7000 series aluminum alloy: contains zinc, has good machinability and corrosion resistance, and is suitable for use under high temperature and high pressure conditions. The common grade is 7075; it is often used in the manufacture of engine parts, hydraulic pipelines, etc.
• 8000 series aluminum alloy: contains tin, has good plasticity and weldability, and is suitable for making containers and pipes, etc. Common grades are 8011, 8021, 8079.

The above are some common aluminum alloy grades and their characteristics. The selection of suitable aluminum alloy grades can be determined according to specific application requirements and conditions of use.
