Metallographic Specimen Preparation for Nickel Iron Bronze Alloys

Nickel-iron bronze is a relatively harder bronze with microstructural preparation for this material being relatively straight forward.

SECTIONING
MAXCUT Abrasive blade (MAX-C or MAX-I series)

MOUNTING
Compression Mounting with Phenolic, Epoxy or Diallyl Phthalate compression mounting resins
