Q1: What are these nickel-based foils, coils, and strips, and what makes them special?
A1: These are high-performance nickel and nickel-based alloys:
Inconel 600 / 725 / X750 / 718: Nickel-chromium alloys with excellent corrosion resistance, high-temperature strength, and oxidation resistance.
Incoloy: Nickel-iron-chromium alloys optimized for high-temperature and chemical resistance.
Nickel N4 / N6 / N8: High-purity nickel strips and coils with excellent corrosion resistance, electrical conductivity, and thermal stability.
Q2: What are the main applications of these products?
A2: They are widely used in aerospace, gas turbines, chemical processing, nuclear power, marine engineering, heat exchangers, battery electrodes, and precision instrumentation due to their high corrosion resistance, strength, and thermal stability.
Q3: How do these alloys compare with stainless steel?
A3: These nickel-based alloys offer superior high-temperature performance, oxidation resistance, and corrosion resistance compared to stainless steel. They maintain mechanical strength and dimensional stability under extreme temperatures and aggressive chemical environments.
Q4: What are the typical mechanical properties?
A4: Tensile strength ranges from 500 MPa to 1200 MPa depending on the alloy, with good ductility (20–40% elongation), high fatigue resistance, and excellent creep-rupture performance at elevated temperatures. Nickel N4 / N6 / N8 strips maintain high purity and electrical conductivity.
Q5: What standards, sizes, and forms are available?
A5: These foils, strips, and coils are produced according to ASTM, AMS, and equivalent international standards. Thickness ranges from 0.01 mm to 5 mm, widths from 5 mm to 1000 mm, and lengths in coils or cut-to-length strips according to customer requirements.
