Nonferrous metals can be divided into heavy metals (such as copper, lead and zinc), light metals (such as aluminum and magnesium), precious metals (such as gold, silver and platinum) and rare metals (such as tungsten, molybdenum, germanium, lithium, lanthanum and uranium).
Generally, non-ferrous alloys have higher strength and hardness, higher resistance and lower temperature coefficient of resistance than pure metals, and have good comprehensive mechanical properties. Commonly used non-ferrous alloys include aluminum alloy, copper alloy, magnesium alloy, nickel alloy, tin alloy, tantalum alloy, titanium alloy, zinc alloy, molybdenum alloy, zirconium alloy and so on.
Function:
Nonferrous metals are essential basic materials and important strategic materials for national economy, people's life, national defense industry and scientific and technological development. Agricultural modernization, industrial modernization, national defense and scientific and technological modernization are all inseparable from non-ferrous metals.
Such as aircraft, missiles, rockets, satellites, nuclear submarines and other sophisticated weapons, as well as parts or components required for advanced technologies such as atomic energy, television, communications, radar and electronic computers, are mostly made of light metals and rare metals among non-ferrous metals.
