Tantalum, renowned as the "biocompatible metal" and king of refractory metals, stands as a cornerstone material in cutting-edge industrial and life science fields due to its exceptional corrosion resistance in extreme environments and absolute biological inertness within the human body.

Tungsten, with its unmatched extremely high melting point, density, and hardness, has become an indispensable key material for addressing extreme environments such as ultra-high temperatures, severe wear, and strong corrosion.

Niobium is a rare refractory metal known for its exceptional combination of high-temperature strength, outstanding ductility, unique superconductivity, and superior corrosion resistance.

Molybdenum products for vacuum furnaces mainly include molybdenum heating elements, molybdenum thermal fields, and molybdenum heat shields, among other key components.
