GH3128 nickel alloy wire is a high-performance Ni-Cr-Fe based material designed for extreme operating environments. With outstanding high-temperature strength, excellent oxidation resistance, and superior mechanical stability, it is widely used in aerospace engines, industrial furnaces, petrochemical equipment, and nuclear applications.
Excellent performance at temperatures up to 980°C (1800°F)
Superior resistance to oxidation, corrosion, and thermal fatigue
High tensile and yield strength with good ductility
Good processability: weldable and formable
Complies with international standards (ASTM B408, AMS 5766, etc.)

A: GH3128 is primarily composed of nickel (≥55%), chromium (20–25%), and iron, with trace strengthening elements such as titanium and aluminum.
A: GH3128 is a Chinese-developed alloy with similar chemical composition and performance to Incoloy 800HT. It is a reliable alternative in many high-temperature applications.
A: Yes. We can provide reports from SGS, TÜV, or other international agencies on request (fees and extra lead time may apply).
A: Yes, it has good weldability. TIG, MIG, and plasma arc welding are all suitable, preferably with matching filler metals.
