  • Aluminum alloy and extrusion
    Patent number: 8252128
    Abstract: A population of extrusion billets has a specification such that every billet is of an alloy of composition (in wt. %): Fe<0.35; Si 0.20-0.6; Mn<0.10; Mg 0.25-0.9; Cu<0.015; Ti<0.10; Cr<0.10; Zn<0.03; balance Al of commercial purity. After ageing to T5 or T6 temper, extruded sections can be etched and anodised to give extruded matt anodised sections having improved properties.
    Type: Grant
    Filed: March 14, 2008
    Date of Patent: August 28, 2012
    Assignee: Alcan International Limited
    Inventors: Nicholas Charles Parson, Barry Roy Ellard, Graeme John Marshall

  • Method of producing an aluminium surface with a high total reflectance
    Patent number: 7169315
    Abstract: A method of producing a reflector sheet, which method comprises treating an Al alloy sheet to increase the total reflectance of a surface of the sheet for use as a lighting reflector by bringing the sheet into contact with an acid or alkaline fluid that dissolves aluminium metal, said fluid having a viscosity of less than 0.01 Pa·s, under conditions to remove from 10 nm to 2000 nm of metal from the surface, and cutting or forming the treated Al alloy sheet into the shape of a reflector sheet.
