Material Characteristics


● Corrosion Resistance:

Excellent performance in corrosive atmospheres (e.g., sulfides, chlorides).


● High-Temperature Stability:

Enhanced creep resistance due to high nickel content.


● Consistent Resistivity:

Minimal fluctuation across temperatures for uniform heating.



Core Advantages


● Extended Lifespan:

40% longer service life than traditional iron-chromium alloys.


● Energy Efficiency:

High resistivity minimizes energy loss and operational costs.


● Customization:

Tailored dimensions and shapes (flat wires, special profiles).



Typical Applications


● Chemical Reactors, Heating in Corrosive Gas Environments

● Electronic Component Sintering, Semiconductor Manufacturing

● Heat Treatment Furnaces, Vacuum Furnaces, Hot Air Circulation Systems
