AMS5666
COMMON NAMES:
Alloy 625
UNS N06625
FORM & USE:
AMS5666 is a corrosion and heat resistant nickel alloy. We stock round bar in the annealed condition. The material is typically used in aerospace, oil and gas and general engineering applications which require corrosion and oxidation resistance up to 1093oC. The material can be welded.
SIZES STOCKED:
12.7 mm diameter – 320 mm diameter.
