The United States Golf Association notified Element 21 Golf Company last week that the companys scandium shaft technology “conforms to the Rules of Golf”. The ruling, Decision 2003-363, enables the company to move forward with sales of the product to golf equipment manufacturers. The company claims the material, scandium, also referred to as “unobtainium,” surpasses the use of titanium and graphite composites.
E21 said in a release that “Scandium has the highest strength to weight ratio of any material used in golf equipment”. The golf shaft ruled on by USGA was manufactured from a U.S. patented scandium alloy with 25% strength to weight advantage over titanium and 40% strength to weight advantage over graphite composite material.
