These copper bars have similar performance properties to beryllium copper, but do not require special machining techniques. They're often used for high-stress applications such as studs, welding electrodes, mold cavities, and electrical components. Even after collisions and frequent use, they maintain their shape. They conduct electricity, but not as well as purer copper, such as 101 copper.
