Highly Durable Thermocouple Wire Type K With For Low-Temperature Research And Industrial Applications

Precision sensing starts with reliable materials. Chengxin Alloy proudly offers high-durability Type K thermocouple wire, engineered specifically for low-temperature environments in scientific research, cryogenic processing, and industrial monitoring systems. Type K thermocouples—composed of Nickel-Chromium (NiCr) and Nickel-Aluminum (NiAl) conductors—are known for their wide temperature range and excellent reliability. At Chengxin Alloy, we optimize Type K wire performance through material purity control, precision alloying, and tight tolerance manufacturing, making our products especially well-suited for low- to moderate-temperature use (typically from -200°C to 800°C).

Chengxin Alloy’s Type K thermocouple wire is engineered for exceptional accuracy and durability in high-temperature environments ranging from -200°C to +1260°C, making it the industry standard for general-purpose thermocouples. Our duplex Type K thermocouple and shielded Type K thermocouple wire options ensure stable signal transmission even in electrically noisy conditions.

Whether you're wiring a K type thermocouple for industrial furnaces, soldering K type thermocouple wire into a lab sensor, or building with Type KK thermocouple assemblies, our wire supports precise temperature monitoring with long-term reliability. The positive leg of the K type thermocouple is made of Chromel (Ni-Cr alloy), and the negative leg is Alumel (Ni-Al alloy)—materials optimized for thermal EMF stability.

Chengxin offers a wide range of Type K thermocouple colours, insulation types, and gauges. For those concerned with cost, our K type thermocouple cable price and wire price remain competitive without compromising quality. Whether you need Type KK wire, are using K type thermocouple for OEM integration, or simply sourcing raw wire Type K thermocouple with full material traceability, Chengxin delivers precision you can count on.
