EFINEA is a leading global supplier of Molybdenum. Molybdenum offers a high melting point and low vapor pressure. Due to its high melting point, it offers a very low creep rate at typical furnace temperatures. The thermal expansion characteristics of Molybdenum are approximately one-third of stainless steels.
The tables below contain the physical, mechanical, chemical, and specifications for Molybdenum. Please contact the sales team at EFINEA if you have any questions or need additional information.
