Because of the metal characteristic and good ductility of aluminum, the purity of the high-purity aluminum segregation block purified and produced by the segregation method can reach more than 99.95-99.996%. The hardness of the high-purity aluminum segregation block is lower than that of other aluminum alloy products, the flexibility in the ductility of the high-purity aluminum segregation block is represented by the soft texture of crystals and the sticky material characteristics among the crystals, and according to the process requirements of the high-purity aluminum segregation method, the high-purity aluminum segregation block is generally subjected to physical segmentation at the position where more impurity elements are required to be removed.
