Molybdenum is a byproduct of copper production used in steel and tungsten to enhance toughness, high-temperature strength and corrosion resistance. The metal can also be used as a lubricant additive in motor oil that can withstand high temperatures and pressures. Molybdenum's melting point of 2,617 degrees Celsius makes it useful in aircraft parts, electrical contacts, industrial motors, heating elements and filaments.
