NOTES:
Ceriated and Multi-strike are
taking over from all other types except Lanthanated.
Ceriated has no radio active emissions and is "environmentally friendly".
Ceriated has a shorter working life than "use specific" types.
Thoriated gives off weak radioactive emissions in decay (Alpha Gamma).
Tungsten melts at approx. 3370ºC
Tungsten grinding dust must be collected by a safe extraction system and
disposed of by an approved method.
