WebBeryllium copper pieces may be wrought or cast and sold in various forms such as plates, rods, strips, and wires. Wrought beryllium copper metals are commonly formed through hot or cold working. Cast beryllium copper pieces are shaped by pouring or injecting molten beryllium copper into a mold. Once the metal is ignited in air by heating above the oxide melting point around 2500 °C, beryllium burns brilliantly, forming a mixture of beryllium oxide and beryllium nitride.
