Molybdenum Plate and Sheet

Description
Molybdenum plate, also named molybdenum sheet, molybdenum heating tape, features high density, balanced internal structure and excellent high creep strength temperature. And its density basically comes close to molybdenum's theory density through rolling and processing with deflection reaching 60%.

Application
Molybdenum plate is widely used as reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, molybdenum sputtering target in physical vapor deposition, high temperature resistance boats in vacuum coating or high-temperature furnace, spare parts in the ion implantation machine, and electric light source parts or electric vacuum components in electric power semiconductor.

Features
1. The purity of pure molybdenum sheet is over 99.95%.
2. The density of molybdenum plate is more than or equals to 10.2 g/cm3.
3. The flatness is less than 2%.
4. Molybdenum heating tape has good performances of high strength, uniform internal organization and good resistance to high temperature creep.
