Industrial Manufacturing And Materials Science

Superconducting technology: liquid nitrogen cools niobium-titanium superconducting coils in MRI.

Material treatment: liquid nitrogen can be used for metal cryogenic treatment, and tools and molds are processed in liquid nitrogen to improve wear resistance. Low temperature stress release of aluminum alloy and titanium alloy. When the tire is recovered, the liquid nitrogen freeze embrittlement is easy to break.

Electronics and semiconductors: During chip testing, liquid nitrogen is rapidly cooled to simulate extreme environments. During vacuum coating, the liquid nitrogen cold trap captures the impurity gas to improve the purity of the coating.
