PING Golf i525 Irons – Graphite
Forged,
Maraging-Steel Face
The
strength of the variable-thickness, maraging steel allows for a thinner, more
dynamic face structure with an internal sole undercut in the 17-4 stainless
steel body to increase flexing for more ball speed and shots that launch faster
and higher with distance control.
“As
we advance all of our iron technologies through our continuous research and
knowledge development, it’s important for golfers to understand the different
attributes engineered into to each model,” said Solheim. “The i525 is
clearly for the golfer in search of more distance. But it offers so much more
performance, including exceptional forgiveness concealed in a players- style
head. Its size and shape are beautifully crafted, and it’s packed with
tremendous technology on the inside, which makes it very appealing to a wide
range of golfers.”
Sound
Engineering
A
polymer is precisely injected onto the inside of the face to improve feel and
sound without interfering with face deflection, the source of its increased
ball speed.
“One
of the biggest challenges we face in designing all clubs is tuning the feel and
sound,” said Solheim. “Because of the i525’s metal-wood-style face design, we
knew sound would require additional attention to ensure the gains in distance didn’t
come at the expense of the feel. We couldn’t sacrifice one attribute just to
improve another. The solution was to inject the polymer in precise amounts to
the same area behind the face. The result is a significant improvement in distance,
sound and feel.”
Extreme
Weighting
Tungsten
toe and shaft tip weights combine with a tiered, dynamic face structure and
cavity to expand the perimeter weighting while preserving ball speed through
greater face deflection for added distance and improved accuracy. The moment of
inertia has increased in the vertical and horizontal axes to provide tighter
dispersion and increased forgiveness.
“The
structure of the face and cavity is a significant mechanical-engineering
accomplishment,” Solheim said. “They function as one to ensure golfers benefit
from the forgiveness PING irons are famous for while maintaining consistent
bending across the face to deliver the added ball speed and higher launch that golfers
expect in a distance-focused iron.”
Friction
Face with MicroMax™ Milled Grooves
Introduced
last year in the i59 iron, the i525’s precision-machined face has MicroMax
grooves for tighter spacing and a geometry that results in an average of four
extra grooves on each club to reduce fliers in the short irons and preserve
spin in the long irons for greater control and consistency. Multi-material
construction: 17-4 stainless steel body; forged, maraging-steel face; tungsten
toe/shaft tip weights; hydropearl 2.0 finish.
