Abstract
Golf clubs, clubheads for golf clubs, and methods for making clubheads are disclosed. An exemplary clubhead includes a rear component and a front component affixed to the rear component. The rear component is made at least partially of a FeAlMn alloy having a density in a range of 6.2 to 7.2 g/cm. The front component includes at least a portion of the face of the clubhead and is made of a material other than the FeAlMn alloy used to make the rear component. For example, the FeAlMn alloy contains (by weight) maximally 1% C, 27-32% Mn, 6-10% Al, 3-5% Cr, maximally 1% Si, and the balance being Fe. The reduced density of the rear component, compared to the density of conventional iron-type clubheads, provides more discretionary mass for manipulation in the clubhead, without sacrificing performance of the face of the clubhead.
