Description

With its unique mechanical and chemical properties, molybdenum is an outstanding material that can meet the most exacting requirements. Because molybdenum possesses a very high melting point, a low coefficient of thermal expansion and a high level of thermal conductivity, it is used in many different industries. Molybdenum is a genuine all-rounder.
