Many new de­signs use ex­otic steel al­loys in the face to im­prove ball speed.

These met­als have what’s called “high ten­sile strength,” which means they can en­dure a lot of stress (some­times 2.45 mega­pas­cals) be­fore fail­ure.The greater the strength, the thin­ner com­pa­nies can make a club­face, which means more ex and less weight. (That saved weight can be used to pre­serve sta­bil­ity on o -cen­tre hits, con­trol spin and en­hance en­ergy trans­fer.)
