There are multiple reasons for alloying beryllium with copper and chromium alloys. The Beryllium Chromium Copper Rod exhibits a host of impressive properties including good hardness, and elasticity, with higher electrical conductivity as well as higher thermal conductivity. The alloy has a high melting point, and hence, the Chromium And Beryllium Copper Hex bar could be used for applications that require high temperatures.

The initial use of these alloys was in the field of defense and as components in the aerospace industries. Beryllium in minute quantities also improves the tensile strength of the copper, making it far stronger than plain copper itself. In addition to having high tensile strength and good hardness, the Beryllium Chromium Copper Flat bar exhibits nonmagnetic properties, as well.

Therefore, the alloy is well suited for use in applications that do not require any degree of magnetism. A higher percentage of copper with significant amounts of chromium and beryllium improve properties such as resistance to corrosion and fatigue resistance in the BeCu Square Bar. Another important property of this alloy is its exceptional ability to dissipate heat, which was the sole reason for the use of a BeCu Round Bar in brakes for military airplanes.
