Component alloy of golf iron head

The invention relates to a component alloy of a golf iron head, which comprises 21.5 to 24.5 weight percent of chromium, 4.45 to 6.05 weight percent of nickel, 0.17 to 0.23 weight percent of nitrogen, 1.5 to 3.5 weight percent of copper, more than 0 and less than or equal to 0.06 weight percent of carbon and the balance more than 0 weight percent of iron. The component alloy has the advantages that: the component alloy has a better integral strength by due to the fact that the plasticity caused by the nickel is reduced by reducing the nickel content of the component alloy and using the copper to substitute for the reduced nickel, so that the golf iron head made from the component alloy is not easily deformed by a strong bump on a golf when hitting the golf; and the component alloy has a strength higher than that of the prior alloy, thereby facilitating the promotion of whole manufacturing efficiency.
