What is beryllium bronze?

In addition to its high strength, elasticity, hardness, wear resistance and fatigue resistance, copper-beryllium binary alloys containing Be < 2.5% have excellent electrical conductivity, thermal conductivity, corrosion resistance, non-magnetism, spark-free when attacked, and excellent technological properties. Widely used in manufacturing diaphragm, diaphragm box, spring tube, spring and other elastic components.
