On the noon of August 1, 2016, tianjin zhongwang aluminum co., ltd. successfully rolled 7055 plates of various specifications for aviation use.

  Due to the high content of alloying elements of brand 7055, the tendency of component segregation and the internal stress, the deformation resistance during rolling is large and casting is difficult.At home, the successful rolling precedent is very few.Tianjin zhongwang successfully rolled this kind of mill by using advanced production equipment and strict process specification

  The successful rolling of 7055 sheet laid a foundation for the subsequent production of 7055-t7751 products.At present, the 7xxx aluminum alloy mainly used in domestic aviation industry is 7075, 7050, 7150, etc., with the strength lower than 7055 aluminum alloy.The tensile strength of the finished sheet of 7055-t7751 reaches 600MPa, with a good combination of strength and damage tolerance. Its successful production will lay a solid material foundation for the production of large aircraft in China.
