Low density and high ductility alloy for a golf club head

Abstract

A low density high ductility alloy for making a golf club head is composed of 31 to 36 w. t. % of Manganese (Mn), 6 to 10 w. t. % of Aluminum (Al), 0.3 to 1 w. t. % of Carbon (C), 4 to 8 w. t. % of Chromium (Cr), 0.2 to 0.6 w. t. % of Silicon (Si), and other component is iron (Fe). The density of the alloy is 6.8˜7 g/cm 3 . The elongation of the alloy is from 33 to 55.4%. The tensile strength of the alloy is 61 to 67% f/mm 2 . The yield strength of the alloy is greater than 35 kgf/mm 2 .
