Parameters

Molybdenum hex nuts possesses a very high melting point, a low coefficient of thermal expansion and a high level of thermal conductivity. Because molybdenum nuts have the ability to withstand extremely high temperatures without changing shape, expanding or softening significantly, they are ideal for high strength / high temperature applications that are shielded from oxygen.

Applications

Molybdenum screws still have good physical strength above 1700 degrees, so molybdenum screws and nuts are widely used in aerospace and aviation science experiments. In the civil sector, molybdenum screws are widely used in vacuum furnaces, single-product furnaces, LED furnaces, glass ceramics and other equipment.
