Is titanium iron or non-ferrous



As Non-ferrous metal Metals are designated that are not iron or do not contain iron or alloys in which iron is not contained as the main element (examples copper, zinc, bronze, brass) Usually the abbreviation "non-ferrous metal" is used for this. Because of their often noticeable color, they are also referred to as non-ferrous metals, but white metals are also non-ferrous metals.

This classification was made because iron is of considerable technical importance and is thus differentiated from the other metals.

Further classifications

Technically used non-ferrous metals are divided as follows:

Pure metals are identified with their chemical symbol and their metal content in percent. In the case of precious metals that are processed into jewelry or coins, there is also a historically based identification in carat or fineness.

For non-ferrous alloys, the labeling is regulated according to DIN 1700. The chemical symbols of the base metal and the main alloying element are given, followed by its alloy content in percent (from a content of over 1%).

The alloy AlMn is accordingly an aluminum alloy with 1% manganese and the alloy CuNi25Zn15 is a copper alloy with 25% nickel and 15% zinc.

Applications

Non-ferrous metals are used in many areas of technology and everyday life:

  • as cast parts (sand, chill or die casting) (zinc, aluminum, magnesium)
  • as a construction material for aircraft and lightweight construction (aluminum, magnesium, titanium)
  • as electrical conductors (cables, busbars, contacts)
  • as bearing materials for vehicle engines (crankshaft bearings, connecting rod bearings), electric motors, ship drives, as gear bearings in general
  • as a coating material for corrosion protection (galvanizing, tinning)
  • for power storage (accumulators, car batteries)
  • as a material for roofing (lead, zinc and copper roofs)
  • as prefabricated parts in house construction (gutters, downpipes)
  • For containers of all sizes in connection with food and luxury goods (drinking cups made of pewter, copper brew kettles, etc.)
  • as jewelry and coin material
