The difference of aluminum6000 and  aluminum 7000

1. Different ingredients

6000 series aluminum alloy on behalf of 6061, mainly contains magnesium and silicon two elements, so the advantages of 4000 series and 5000 series 6061 is a cold treatment aluminum forging product.7000 series aluminum alloy represents 7075, mainly contains zinc element.

2. Different applications

6000 series aluminum alloy is suitable for corrosion resistance, oxidation requirements of high applications.Good usability, easy coating, good processability.7000 series aluminum alloy belongs to aviation series, is aluminum magnesium zinc copper alloy, is heat treatment alloy, belongs to super hard aluminum alloy, has good wear resistance.It also has good weldability, but poor corrosion resistance.
