Title:
METHOD FOR PRODUCING AN ALUMINIUM ALLOY PART
Document Type and Number:
WIPO Patent Application WO/2021/156582
Kind Code:
A3
Abstract:
The invention relates to a method for producing a part, comprising the production of successive solid metallic layers (201…20n), each layer being produced by depositing a metal (25) called filler metal, said filler metal consisting of an aluminium alloy comprising at least the following alloying elements: - Zr, in a mass fraction of 0,60 to 1.40%; - Mn, in a mass fraction of 2.00 to 5.00 %; - Ni, in a mass fraction of 1.00 to 5.00 %; - Cu, in a mass fraction of 1.00 to 5.00%. The invention also relates to a part obtained by means of this method. The alloy used in the additive manufacturing method of the invention makes it possible to obtain parts with exceptional properties.
