What are the quality requirements for aluminum ingots for aluminum alloy processing materials?

A chemical composition meets national standards or relevant technical standards

      The chemical composition of the aluminum ingot is uniform, and the degree of aggregate segregation satisfies the relevant technical requirements.

The structure of the two aluminum ingots is small, dense and uniform, in line with relevant technical standards.

      Fine refers to small as-cast grains and fine crystal structure; compact refers to defects that have little or no damage to the ingot connection, such as porosity, porosity, slag inclusion, oxide film, white spots, crystal layer splitting, cracks, etc. The degree of structural non-uniformity caused by defects such as "homogeneous" main crystal, feather crystal, metal compound primary crystal, crystal, coarse suspension crystal, coarse equiaxed crystal, etc. should be within the required range.

The surface quality of the three aluminum ingots meets the technical standards.

     Surface quality refers to the depth of layering and cracking, the height of segregation, softness and metalloma, surface slag area and depth caused by surface wrinkles and surface layer segregation.

The geometry of the four ingots and ingots meets the pressure requirements.

     Geometric dimensions refer to the length and tolerance of the ingot and ingot, the inner and outer diameters and tolerances, the thickness of the west face, the slope, the unevenness of the wall thickness, the degree of bending of the face and the depth of the surface, and the surface roughness of the skin. .
