When it comes to selecting iron shafts, graphite vs steel continues to create debate among golfers at all skill levels.

As far as drivers, fairway woods, and hybrids are concerned, the train has left the station with the majority of players using graphite for some time. Graphite offers performance benefits that are impossible to achieve with steel including

• Graphite can be made much stiffer at lighter weights
• Bend profiles can be uniquely tuned thanks to multiple materials and composites (steel is a homogeneous material and very limited in this capacity)
• Graphite has greater shock-absorbing properties to help reduce vibrations transferring to a players hands

It used to be that graphite shafts were only for slower speed players who needed something that was lighter and more “whippy,” but that was a big misconception that continues to have some staying people with golfers unfamiliar with modern technology.

The benefits of graphite shafts in irons

The benefits of graphite shafts in irons vary depending on the weight category they fall into. The weight categories also generally coincide with player swing profiles, which give golfers and fitters the best chance to see a performance gain.

• >40-65 grams: The shafts in the lightest weight category offer players on the slow end of the swing speed spectrum the opportunity to generate more speed and additional high and spin on their shots. There are no steel shafts that are able to fit into this weight range, and graphite opens the door to a lot more players to enjoy that game thanks to total club weight reduction.
• 65-95 grams: This is the biggest portion of the graphite shaft market and where most golfers are going to fit in. The lighter weight shafts in this range continue to help golfers that are looking for extra speed, while the heavier options are a great transition point for players looking to move away from steel. One of the biggest reasons for a golfer to transition into graphite from steel in this weight range would be for vibration reduction, or in some cases to get extra stability unavailable in lighter weight steel compared to the graphite equivalent. Depending on the shaft, 90-gram graphite shafts are just as, if not more stable than, steel.
• 95-120+ grams: These shafts are for the fastest players, and from a materials and design perspective graphite, shafts in this weight range can be made extremely stiff —beyond the point of similar steel shafts. The argument used to be that graphite didn’t offer the same tight dispersion as steel, but that has been proven false and one of the biggest benefits for golfers looking in this category if all the stability (if not more) of steel but with greater injury/pain prevention.

Proven results

Graphite shafts have been commonly used on the PGA Tour for over a decade by players including Brandt Snedeker, Fred Couples, and Matt Kuchar, for the same reason regular weekend golfer use them—lighter weight and extra stability.

When speaking of stability, it was just over a year ago that PGA Tour player Bryson DeChambeau went from steel in his irons to graphite and became the first golfer on the PGA Tour to use 14 clubs with graphite shafts. The designer of those shafts had this to say about working with graphite,

“The versatility of composite materials allows us to add stiffness, drop torque, move the balance, and modify the flex profile without adding additional weight.”

It’s this kind of design versatility that benefits golfers at all levels.

Graphite versus Steel a deeper look
