Nickel-Chromium Alloy Wires
Cr15Ni60 resistance wire
- Features:
-
Cr15Ni60 is a type of medium-nickel Nichrome resistance wire with a nickel content of approximately 60%, achieving a balance between cost, performance, and reliability. After solution treatment, the metallographic structure of Cr15Ni60 is a single-phase austenitic structure, which remains stable during use. Cr15Ni60 has high plasticity, good cold stamping and welding performance at room temperature, and also exhibits excellent oxidation resistance, thermal strength, and positive temperature coefficient in high-temperature environments.
- Cr15Ni60 Resistance Wire is also known as Chromel C, Nikrothal 60, N6, HAI-NiCr 60, Tophet C, Resistohm 60, Cronifer II, Electroloy, Nichrome, Alloy C, Nikrothal 6, MWS-675, Stablohm 675,60/15 Nichrome,NiCr60/15,Cr16Ni60
- Advantages:
- Cr15Ni60 has high resistivity, good oxidation resistance and excellent form stability. Cr15Ni60 offers significant advantages for medium-temperature heating applications where cost-effectiveness is a priority. While it has lower maximum operating temperature compared to Cr20Ni80 and Cr30Ni70, its excellent ductility, weldability, and stable electrical properties make it the preferred choice for household appliances, industrial heating equipment below 900°C, and precision resistors where budget considerations are important.
- Specifications:
- Bright and soft annealed finish: 0.025 - 1.6mm; Acid-pickled finish: 1.0 -12.0mm; Rods: 6.0-150.0mm
Flat wire: width from 0.2 - 6.0mm and thickness from 0.08 - 1.0mm; Wide strip: width from 5.0 - 300mm and thickness from 0.05 - 4.0mm
