Molybdenum is not as hard as Class 13 but can be drilled and machined to special contours. With relatively good thermal conductivity, molybdenum has a melting point of 2,623 ºC (4,753 ºF) and has one of the lowest coefficients of thermal expansion among commercially used metals. Suited for cross wire welding of copper and brass, resistance brazing and some upsetting, also welding of braided copper wire to other materials.
