Metal Materials

Metal Materials are materials that have properties such as gloss, ductility, easy electrical conductivity, and heat transfer.

Usually divided into ferrous metals, non-ferrous metals and special metal materials.

① Ferrous metals are also called iron and steel materials, including industrial pure iron with a total impurity content of <0.2% and a carbon content of not more than 0.0218%, steels with a carbon content of 0.0218% to 2.11%, and cast iron with a carbon content greater than 2.11%. In the broad sense, ferrous metals also include chromium, manganese and their alloys.

② Nonferrous metals refer to all metals and their alloys except iron, chromium, and manganese. They are usually divided into light metals, heavy metals, precious metals, semi-metals, rare metals and rare earth metals. In addition, the resistance is large and the temperature coefficient of resistance is small.

③Special metal materials include structural metal materials and functional metal materials for different purposes. Among them are amorphous metal materials obtained through the rapid condensation process, as well as quasicrystals, microcrystals, nanocrystalline metal materials, etc .; and special functional alloys such as stealth, hydrogen resistance, superconductivity, shape memory, wear resistance, vibration damping And metal matrix composites.
