Abstract
Disclosed in the present invention is a low-coercivity wire rod, which contains Fe and inevitable impurities, and further contains the following chemical elements in percentages by mass: 0<C≤0.003%, Si≤0.01%, Mn: 0.1-0.2%, Al: 0.30-0.45%, O: 0.0015-0.0035%, N: 0.001-0.003%, and Ca: 0.0005-0.0015%. Correspondingly, further disclosed in the present invention is a manufacturing method for the wire rod. In the present invention, by means of a rational chemical component design and structural regulation, a wire rod having low coercivity can be obtained.
