Commercially pure


Commercially pure materials, usually metals, are ones that have been purified to a practical extent, sufficient for commercial purposes; that is, they are close to absolute/theoretical purity albeit with some low-but-nonzero tolerance for impurities that allows for their economically viable production cost.
Major examples include:
  • Commercially pure titanium: see Titanium § Commercially pure titanium
  • Commercially pure zinc: see Zinc § Commercially pure zinc
  • Commercially pure aluminium: see ''Aluminium § Applications''
