  • Patent number: 10591005
    Abstract: A method for the production of braking elements for vehicles, in particular brake pads, includes a die forming step by means of fine and/or traditional shearing of a metal support and a molding step upon the metal support of a block of friction material. The friction material is selected from the group of asbestos free materials, while the metal plate is made of an aluminum alloy selected from the group consisting of aluminum alloys subjected to precipitation hardening (age-hardening alloys) and is made from the fine and/or traditional shearing of a metal sheet when the alloy is in a solubilized state. The alloy is not age hardened until a friction material baking step in order to gain the mechanical properties needed for its operation.
