Categories and heat treatment characteristics of 1-8 series aluminum materials

Many customers are not familiar with the hardness and types of aluminum materials they use, so there is often a big difference between the material hardness and the requirements in the purchase. The problem of heat treatment is a headache for many customers. Today, Xinyitong Aluminum will talk to you about the types of 1-8 series aluminum materials and the characteristics of heat treatment.

Pure aluminum: as the name implies, 1-series aluminum, with aluminum content up to 99%;

Rust proof aluminum: 3-series and 5-series aluminum, with good corrosion resistance and higher aluminum strength;

Hard aluminum: 2 series aluminum, the main alloy element is copper, with high strength, but poor corrosion resistance;

Super hard aluminum: 7 series aluminum, the main alloy element is zinc magnesium copper, with ultra-high strength and good wear resistance. The disadvantage is that there is a tendency to stress corrosion cracking;

Wrought aluminum: 6 series aluminum, the main alloy element is magnesium silicon, with medium strength and good oxidation effect;

Welding steel: 4-series aluminum, with silicon as the main element, low melting point, good wear resistance and heat resistance.

Aluminum materials are divided into two categories: non heat treatable strengthened aluminum alloy and heat treatable strengthened aluminum alloy:

Non heat treatable strengthened aluminum alloys include pure aluminum (Series 1), AL Mn (Series 3), and AL Si (Series 4),

Al Mg (series 5), Al Li (series 8) alloys, etc.

Heat treatable strengthened aluminum alloys: Al Cu (system 2), AL Mg Si (system 6), Al Zn Mg (system 7), etc.
