  • Method of forming parts from sheet metal alloy
    Patent number: 11441216
    Abstract: A method of forming a part from sheet metal alloy is provided, for example, forming a part from aluminium alloy. The method comprises heating (A) the sheet metal alloy to a temperature at which solution heat treatment of the alloy occurs and so as to achieve solution heat treatment. The sheet is cooled (B) at at least the critical cooling rate for the alloy and then placed between dies to form (C) it into or towards the part.
    Type: Grant
    Filed: November 4, 2019
    Date of Patent: September 13, 2022
