- Incoloy 925 Nickel Alloy Wire UNS N09925 1366°C Melting Point High
Performance Nickel-Based Alloy Wire
Incoloy 925 wire is a high-performance nickel-iron-chromium alloy
wire with excellent corrosion resistance and high strength. It is
widely used in chemical, marine, energy and medical fields. Its
main components include 42%-46% nickel, 19.5%-22.5% chromium,
2.5%-3.5% molybdenum and 1.5%-3.0% copper, which give it excellent
resistance to pitting, crevice corrosion and chloride ion stress
corrosion cracking.
Incoloy 925 wire has excellent mechanical properties, with a
tensile strength of ≥965 MPa, a yield strength of 758-965 MPa, an
elongation of 18%-27%, and a hardness of up to 38 HRC. It performs
well in both oxidizing and reducing environments, especially in
sulfuric acid, hydrochloric acid and marine environments. This
alloy wire can be used to make welding wires, spring wires, heat
exchanger components, submarine pipelines and medical devices, etc.
It is an ideal material for handling high temperatures and
corrosive media.
