Application of Mo-La Alloy Sheet
1. Mo-la sheet (Mo-la alloy sheet) means molybdenum and lanthanum alloy sheet. They are used for producing tungsten and molybdenum electrodes, heating elements, heat shields, sintering trays, sintering boats, stacking sheets, base plates, sputtering targets, crucibles in electronic and vacuum applications. La2O3 prevents dislocation motion of the molybdenum crystalline grain and slow the pace of recrystallization under high temperature. The usability and service life of the Mo-la sheet has been greatly enhanced.
2. Mo-la alloy sheet is also widely used for producing reflecting screen and cover inside sapphire crystal growth furnace, reflecting screen, heating tape as well as connection inside vacuum furnace.
Features
1. The density of Mo-La sheet is substantially close to the theoretical density of the molybdenum after the deformation amount of rolling process;
2. Mo-la alloy sheet has good properties of high strength, uniform internal organization and excellent resistance to high temperature creep;
3. We produce Mo-la alloy sheet with smooth surface, no double skin, no stratification, no crack and no impurity;
4. The key production technology lies in the quality of raw materials and standardized operating procedures;
5. Mo-la sheet from Achemetal is under vacuum annealing and leveling before delivery;
6. It is approved by ASTM B 386-2003 and GB 3876-2007 and GB 3877-2006.
Production Process of Mo-La Alloy Sheet
The production process of Mo-la sheet is of high strictness. The whole production processes are: Molybdenum Billet - Inspection - Hot Rolled - Leveling and Annealing - Alkaline Cleaning - Test - Temperature Tie - Vacuum Annealing - Inspection - Cold Rolling - Leveling - Shear Vacuum Annealing - Inspection – Packaging.

We can also provide Mo-La alloy sheets according to customers' requirements.
Package and Inspection
We offer material composition sheet and examination report which include density, flaw detection, dimensions and so on. Our products are packed in plywood case with expanded plastic.Every piece of Mo-la sheet is separated from water proof paper.
Owning two hot rolling machine and five cold rolling machines, Achemetal Furnace Co., Ltd. can supply vacuum annealed tungsten and molybdenum foil, sheets, plates, discs, squares and ribbons with high density and excellent mach inability. Excepting Mo-La alloy sheet, we also produce other rolled tungsten and molybdenum products, such as tungsten and molybdenum sheet, tungsten and molybdenum plate, tungsten and molybdenum discs, etc. All of our products are made in accordance with the standard of ISO9001.
