Brush II and C.Baldwin Sawyer started Brush Laboratories (1921), one of the first laboratories to further understand and explore commercial/industrial uses for beryllium. In 1926, the true value of beryllium was discovered. Beryllium was perfect as a precipitation hardener in cooper and nickel. Corson patented a beryllium-cooper-nickel alloy in United States. In Germany, around the same time as Corson's patent, Siemens, the German electrical components company, patented binary alloys of beryllium-cooper-cobalt in Germany.
