Product Process
Cr20Ni30 (also known as Nichrome 30/20 or NiCr 30/20) is a nickel-chromium heating alloy plate specially designed for high-temperature electric heating elements. It is widely used in industrial furnaces, kiln heating elements, toaster ovens, infrared heaters, and resistance heating systems requiring stable performance up to 1150–1200°C.
Cr20Ni30 (NiCr 30/20): Contains ~30% nickel and 20% chromium, offering better high-temperature strength and oxidation resistance at lower cost.
Ni80Cr20 (Nichrome 80/20): Contains 80% nickel, provides higher electrical resistivity and is more suitable for applications up to 1200°C with longer service life.
Cr20Ni30 is more popular in cost-sensitive industrial heating projects in China and Asia.
