Molybdenum foil is produced by cold rolling the molybdenum sheet to a lower thickness. As a recognized molybdenum foil manufacturer, CHEMETAL takes pride in offering our customers the highest quality molybdenum foil with a range of thickness from 0.08 inches (2 mm) to less than 0.001 inches (0.025 mm). The typical thickness of molybdenum foil is 0.06 mm to 0.1 mm which is cold rolled by 20 rolls reversible mill. All molybdenum foils at CHEMETAL are subject to various tests in order to meet our customers’ specifications. Moreover, we are also dedicated to implementing stringent quality control for each step of molybdenum foil manufacturing starting from the molybdenum powder to our finished moly foil. The molybdenum surfaces we supply include mirror, matte and smooth.

Molybdenum Foil Applications
The stamped and drawn foil is very suitable to use in the applications of high temperature vacuum furnace, coating, electronic and semiconductor components. Molybdenum are used to make heat shielding, heating element and carrier of the vacuum furnace. It is because Molybdenum foils process a high heat resistance in the high temperature environment.
In addition, Molybdenum foil owns an extremely Low Vapor Pressure and a high melting point so that it is ideally served for coating application as the evaporation boat. Moreover, the ideal material for semiconductor needs to have a Low Coefficient of Thermal Expansion and Low Electrical Resistivity. Molybdenum can meet these requirements. Therefore, it is a very suitable material for components of the semiconductor industry. Molybdenum has been also approved to be a promising material to explore in further in medical and Sputtering applications. For example, molybdenum foil substrates for solar cells helps solar device yield a high energy conversion efficiency.
