7075 T651 is used in especialy aerospace and many fields.When it will be uses as uniform large plate 7075 T7351 is preferred particularly in large diameters because of insufficient stress corrosion cracking resistance of 7075 T651. In cases where it will be used as uniform aluminum sheet with large dimensions, When used in large dimensions AMS, ASTM selection becomes very important., with this selection 7075 T7351 provides high resistance to both high tensile corrosion and high machinability without distortion problems in perfect precision tolerances. Referans Metal supplied this aluminum material to Turkish Market as first time importing in the market in the year 2006 with The Original Material Supplying method and material used first time for Turkish space industry project.
