Warranty: 2 years Export or domestic sales: domestic sales Aluminum alloy has a relatively light weight, good thermal conductivity and corrosion resistance, which meets the requirements of lightweight, energy saving and emission reduction in automobiles. Therefore, the use of cast aluminum alloy to manufacture automotive transmission case covers is a development trend. However, aluminum alloy workpieces are prone to various surface defects, mainly manifested as black spot defects. A literature review has analyzed the black spot defect on the surface of 5A02 aluminum alloy flange forgings and determined that it is caused by organic medium pollution; Black spot defects were found on 7A04 aluminum alloy products, which include corrosion by corrosive su…
