Randol ‘ is an alloy of copper (Cu) (97%) with beryllium (Be) (0,5-3%) with different additives of other metals (Nickel, chrome, magnesium). This alloy is also known as beryllium bronze and “Gypsy gold”. In appearance similar and indistinguishable from gold.

Randol ‘ is used for the manufacture of mechanical tools which can be used safely in an environment containing explosive gases, for the manufacture of jewelry in order to imitate gold, for the manufacture of springs, spring wire, torque sensors, and other design elements that should maintain its shape over periods of cyclic compression and tension, for the manufacture of aerospace instruments and so on.
