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).
