NEORIUM S and NEORIUM H

Cautions
  • For use in Argon Gas Atmospheric Melting Chambers only
  • Not for use in Arc Casting Chambers

 

Uses

Full Denture Bases, Partial Denture Bases, Bars and Clasps

 

Features
  • Difficult to break, flexible casting achievable.
    Therefore the amount of adjusting to prevent casting defects is greatly decreased.
  • Extractability from the investment material is excellent. Especially effective when used with Yamahachi investment Neowhite, the casting is easily removed from the investment material.

■Hard to break even if casting deformation is adjusted.
Due to sufficient elongation property, production of supple and hard to break casting is possible.

■Neorium is made from powder metal ingredients.
Compared to the dissolution method of production, the powder sintering method of production improves the alloyʼs physical properties because it utilizes more nitrogen and contained stably.

 

  • Less deterioration even after reuse.
