Latest Patents

John Ridley holds a patent for a formable aluminum alloy sheet product. This aluminum sheet is formed from an alloy containing Fe 0.6-1.0%, Si 0.5-0.9%, and Cu 0.3-0.5%. The alloy also includes Ti and B in conventional grain refining amounts. While Mn is permissible in amounts up to 0.2-0.3%, it is preferably held below 0.1%. The Mg impurity content is maintained at a very low value to avoid difficulties with lacquer adhesion. The primary use of this sheet product is for the production of bottle closures, and it is ideally produced in a thickness of 0.15-0.25 mm, featuring a low percentage of earing and fine grain size. The sheet undergoes a temper cold rolling reduction of 30-60% after the last interannealing treatment, ensuring its quality and performance.
