What It Measures
What the wire does at impact
Strength-to-Weight
Wire elements add stiffness where the layup needs it without adding weight to the finished shaft.
Torsional Stability
Published torque runs from 4.5° in the 40g class down to 2.5° in the 70g class, tightening as the player gets stronger.
Tighter Dispersion
A stable tip section through impact is designed to keep face rotation, and therefore dispersion, consistent on off-center hits.
Repeatable Numbers
Weight held to ±1 g and the tip diameter to ±0.002" (±0.05 mm), so two shafts of the same spec build the same.
What the fitter sees
Weight ±1 g, torque 2.5°–4.5° by class, mid or mid-high kick point, 0.337" (8.55 mm) parallel tip.
The published spec sheet, not the material story, is what to fit against.
The Structure
Why an amorphous structure behaves differently
Attomax uses amorphous metal alloy wire as an element within the carbon layup of ATOM shafts. Three properties of that wire account for everything above.
- No grain boundaries
- Crystalline metals fail along grain boundaries. An amorphous (non-crystalline) structure has none, which removes those weak points.
- High elastic limit
- The wire can store and return more elastic energy before it deforms, which is why it is used as an energy-return element in the layup.
- Corrosion resistance
- The same structure resists corrosion, so the wire keeps its properties over the life of the shaft.
Molecular Structure
Amorphous Non-Crystalline
Tightly packed · Efficient energy transfer
- Amorphous Metal (Metallic Glass)
- Materials Science · Golf Technology
- A class of metals with a non-crystalline molecular structure and no grain boundaries. First produced at the California Institute of Technology (Caltech) in 1960, amorphous metals combine a high elastic limit, high strength and corrosion resistance. Attomax Pro uses amorphous metal alloy wire in the carbon layup of ATOM golf shafts.

Technology FAQ
What is amorphous metal technology in golf shafts?
Amorphous metals, also known as metallic glass, are metals with a non-crystalline structure. Because they have no grain boundaries, they have a high elastic limit, high strength and good corrosion resistance. Attomax uses amorphous metal alloy wire as an element within the carbon layup of ATOM shafts.
How does Caltech research relate to Attomax Pro technology?
Attomax Pro technology builds upon groundbreaking amorphous metal research that originated at Caltech, where the first metallic glass was produced. Dr. Paul Kim from Caltech researched our amorphous metal powder technology and currently works with the Attomax team to develop our innovative golf shaft technology.
What makes amorphous metal shafts better than traditional golf shafts?
The amorphous metal wire in the ATOM layup is chosen for its high elastic limit (energy return), its contribution to torsional stability, and its corrosion resistance, without the grain-boundary weak points of crystalline metals. The shaft you fit is still defined by its published numbers — weight, torque, kick point and dimensions — which are on the spec sheet.
Where are Attomax Pro shafts manufactured?
Our manufacturing process spans three continents: Advanced amorphous metal materials are produced in South Korea, final assembly and quality control occur in Japan using meticulous craftsmanship standards, and design engineering is based in California, USA.
Is Attomax Pro the first company to use amorphous metal in golf shafts?
Yes, Attomax Pro pioneered the development of golf shafts using amorphous metal alloy wire, setting a new standard in performance and durability. This world's first innovation represents a significant leap forward in golf equipment design.
