5N (99.999%) Copper (Cu) Pellets Evaporation Materials

Copper (Cu) is one of the most highly utilized elements in the world with evidence of its usage found during ancient times. It is reddish-orange in color with a melting point of 1,083°C, a density of 8.92 g/cc, and a vapor pressure of 10-4 Torr at 1,017°C. Due to its excellent conductor of heat and electricity, it is widely used in wire, coins, and electromagnets. The vacuum industry relies heavily on copper material for backing plates which are bonded to sputtering targets. It is a popular evaporation materials for semiconductors, sensors, and circuit devices.
