Products / Molybdenum Tubing
Molybdenum Tubing
Molybdenum (Moly) is a soft, ductile refractory metal that can withstand temperatures up to 2,000°C which makes it the perfect material for Nanmac’s high- temperature thermocouple probes. Our Moly tubing is available in almost any standard size and configuration and can come either open on both ends or welded shut on one end for easier thermocouple assembly.
