6000 Series Aluminum Chemical Properties

Introduction of 6000 Series Aluminum

6000 series aluminum refers to the division of Al-Mg-Si alloy. It mainly contains magnesium and silicon elements to form a strengthening phase Mg2Si. Its solubility is chemically reacted with other added elements at different solution temperature, so add The type and content of the elements affect the 6000 series aluminum properties. At the same time, 6000 series alloy also concentrates on the advantages of 4000 series and 5000 series, including alloys such as 6005, 6060, 6061, 6061 t6 sheet, 6061-T651, 6063, 6063-T5 aluminum plate, 6063-T6, suitable for anti-corrosive and oxidizing applications.

6000 Series Aluminum Chemical Properties

The Mg and Cr elements in 6005 aluminum are slightly increased to form a modified alloy 6005A, which hinders the recrystallization or recrystallization grain growth during extrusion and after extrusion, so that the cast grain size defects are basically absent.

For 6061 aluminum plate, if add a certain amount of Mg and Cr, can neutralize the bad effect of iron. Sometimes a small amount of Cu or Zn is added to increase the strength of the alloy without significantly reducing its corrosion resistance. If Mg2S is dissolved in aluminum, the alloy has an artificial age hardening function.

The content of Si and Cu in the 6063 aluminum plate is relatively reduced, which affects the solubility of the alloy. At the same solution temperature, the alloy exhibits different strength, hardness and heat resistance.

Features and Use of 6000 Series Aluminum
