Abstract (en)
[origin: WO2022167327A1] The present invention relates to an antiferromagnetic alloy made up of: - 15.0% to 35.0% by weight manganese; - 4.0% to 15.0% by weight chromium; - 1.0% to 5.0% by weight vanadium; - 0.1% to 2.0% by weight carbon; - 0.1% to 1.0% by weight silicon; - 0% to 2.0% by weight aluminium; - with the remainder being iron and residual impurities. This alloy can be used in the field of horology, in particular for manufacturing a timepiece movement component.
