Mitsubishi Chemical America Inc. Sporting Goods Division is a wholly owned subsidiary of Mitsubishi Chemical Holdings Corporation, dedicated to designing and developing the highest performing composite golf shafts for discerning golfers everywhere.

Mitsubishi Chemical credits its premium quality to an ability to make golf shafts from scratch.

This vertical integration means that along with manufacturing the finished product, Mitsubishi Chemical also manufactures the critical raw materials which include the monomer, acrylic fiber, carbon fiber, resent, and prepreg. Over the last 30 years, the company has developed over 1,000 formulations of resin and 100 types of fiber for its performance-based applications which range from aerospace to premium golf shafts.

Mitsubishi Chemical and partner Aldila are among the world’s biggest manufacturers of carbon-based composite shafts and operate in the United States under the umbrella of MCA Golf, Inc.

Aldila was established in San Diego in 1972 by visionary and the so-called “Thomas Edison of modern golf” Jim Flood. The Aldila team was responsible for the invention of the carbon fiber shaft which proved to be more flexible and lighter than the heavy steel shafts of the time while still maintaining strength.

In 2013, Aldila, Inc. was acquired by Mitsubishi Chemical and, today, both brands operate out of the same corporate headquarters in Carlsbad, California. Together, the brands have produced some of the highest quality and most popular shafts in the industry.

Popular shaft models under the Mitsubishi Chemical and Aldila brand names include Diamana, TENSEI, Kuro Kage, Ascent, Synergy, and Rogue. With each new product line and innovation, Mitsubishi Chemical continues its history of providing some of the most technologically advanced products on the market. In 2021, along with the new Ascent line of golf shafts, the company introduced Focused Mass Technology. This technology was designed to provide the feel of an ultra-lightweight shaft that counters the tendency for the face to remain open at impact. This innovation incorporated into the tungsten-infused prepreg to produce a stronger and straighter ball flight.

The continued innovation and pursuit of excellence that Mitsubishi Chemical has displayed since entering the golf shaft market has led to the company becoming one of the most trusted brands in the industry for OEMs and major tour professionals.


Aldila’s 2013 absorption by Mitsubishi Rayon a decade ago was a significant move in the company’s history. The numbers bear out Aldila’s primacy on tour and the Victory acquisition adds a measure of diversification to the company’s portfolio.

Additionally, existence under the Mitsubishi umbrella offers both the physical and capital resources of Mitsubishi Chemical and its shafts.

Aldila holds the noteworthy distinction of being the first graphite shaft brand to be offered as the stock option on a major OEM’s driver: Callaway’s 1991 “Big Bertha with Aldila.”
