What are the characteristics, causes and preventive measures for the smear of aluminum alloy bars?

        Smudges (water marks, oil marks, graphite traces) are corrosion spots on the surface of aluminum alloy sheet products, and most of the stains appear in a circle, which often occurs during extrusion, and also occurs during aging treatment after straightening. Smudges are easily produced in high-grade aluminum alloys and can sometimes be eliminated by corrosion. The water version is usually light gray and the oil spots usually appear brown.

      (1) Causes of smudging of aluminum alloy bars

                The workbench leaks and leaks oil;

                The quenching agent is contaminated or not cleaned;

                Oil stains adhering to the surface and graphite are not removed in time;

       (2) Preventive measures for smudging of aluminum alloy bars

                 Timely repair the leaking oil leakage position, the water and oil on the product should be wiped clean or kept dry in time;

                 Oil, graphite and other contaminants adhering to the product should be removed in time;
