Intercrystalline corrosion of 5 series aluminum alloys
Detection Content

Detection Purpose: To test the resistance of aluminum alloy to intercrystalline corrosion

Detection range: 2 series, 5 series, 7 series and other aluminum alloy and aluminum alloy products

Intergranular corrosion intergranular corrosion


Corrosion along or near grain boundaries of metal grains.


Intercrystalline corrosion test of 5 series aluminum alloy


The sample of 5XXX aluminum alloy plate products was immersed in concentrated nitric acid at 30℃ for 24 hours to measure the mass loss per unit area and conduct metallographic analysis on its cross section to assess the sensitivity of intercrystalline corrosion.
