Pfinodal - 1

AMETEK* SPECIALTY METAL PRODUCTS Innovative & Advanced Metallurgical Technology Description Spinodal hardened alloys are characterized by regular submicroscopic chemical composition fluctuations. These chemical fluctuations occur spontaneously at the aging temperature and their formation is called spinodal decomposition. In the case of Pfinodal, the copper, nickel (15%), and tin (8%) alloying elements are homogeneous throughout the manufacturing process prior to aging. Mill processing requires a solution anneal and quench step to produce a homogeneous single-phase structure. This is followed by cold work and finally a low temperature aging step. The amount of cold work, aging temperature, and time all affect the strength and formability of the final Pfinodal product. AMETEK’s patented powder metallurgy process accomplishes this uniformity, thus ensuring optimum reproducible properties.

Exceptional Corrosion Resistance in the Harshest Environment Superior Pfinodal Properties using Patented PIF Process Pfinodal parts can withstand highly corrosive industrial environments without pitting. It performs exceptionally well in standard salt spray tests. C72900 meets NACE MRO175. Ametek’s Pneumatic Isostatic Forging (PIF) patented process produces fully dense material. PIF is a true forging process that uses uses high pressure gas to close porosity, thereby increasing density while improving the microstructure of the material. For CuNiSn alloys, the PIF process is an ideal...
