Although the first production of 7075 T651 aluminum sheet / plate and bar had emerged for the aviation-defense industry, usage of it in the machinery, packaging, molding and instrumentation industry has already exceeded the aviation industry. The alloy is somewhat like a gift coming from the aviation industry to the machine-mold industry. 7075 T651 has dominantly ceased the favoring of some of the branded 7000 series aluminum alloys, such as Hokotol, Alumold, Certal, Alumec just because they have higher hardness values. 7075 T651 provides a shocking satisfaction when produced from a factory supplying with high homogeneity and maximum relieving inner stress. With the introduction of 7075 T651 aluminum in the round bar form, it has almost completely replaced its engineering steel equivalent.
