Cr20Ni35 Nichrome wire is composed of approximately 35% nickel, 20% chromium, and the balance iron. This balance creates a wire that is strong, durable, and capable of operating continuously at temperatures up to 1100°C. Unlike higher-nickel Nichrome grades, Cr20Ni35 provides a balance between mechanical strength and electrical stability, making it ideal for resistor applications where precision and repeatability are critical.

The alloy’s electrical resistivity is around 1.05 μΩ·m at 20°C. It maintains this resistivity with remarkable stability across a wide temperature range, ensuring consistent resistance values in precision resistor manufacturing. The wire can be drawn into fine gauges without sacrificing strength, and DLX supplies it on spools or coils to suit various production needs.
