Product Name: Mirror-finished Mo Wafer Moly disc molybdenum wafer
Mirror polished molybdenum wafer--produced by Luoyang Starto Metal Co.,Ltd. has high purity, good roughness and high flatness. Our Mo wafer manufactured from high-purity molybdenum plate via punching and professional polishing processes, features flawless mirror surface, widely applied in high-end industrial fields including semiconductor and aerospace industries.
All our molybdenum products’ purity≥99.95%. Our Mo wafer with mirror surface of course also has excellent mechanical strength, electrical conductivity and thermal conductivity. It serves steadily as molybdenum disc for high-temperature furnaces and molybdenum substrate for precision optical instruments.
Mirror-finished molybdenum wafer is an essential material in semiconductor manufacturing. Mirror polished Mo disc surface roughness is controlled within Ra ≤0.02㎛, actual finished surface could be Ra 0.005㎛. And the flatness, some people call cross bow, could be as flat as 3-4㎛.
Recently, we are preparing the sample of Mirror polished wafer as dia100*0.098mm. Customer required Ra＜0.03㎛, our roughness test result is between Ra 0.015~0.025㎛. The cross bow requirment is ＜150㎛, our test result is around 100㎛. Surface as shown in the picture.
We will report more information after customer's feedback.

Part of testing details for Moly wafer with mirror surface:
Each molybdenum disc is individually sealed with vacuum anti-static package to avoid oxidation and surface scratch. Molybdenum wafers are packed 25 pieces per 4-inch wafer box and vacuum sealed secondarily. Or a thin paper between each Mo wafer, and load them in a can, protected by EPE foam.
Storage: Keep molybdenum parts in dry room temperature environment, stay away from humid and acidic surroundings.Cleaning: Remove oil stains with alcohol or acetone; do not wipe surface with abrasive materials.
·Adopt powder metallurgy production, followed by rolling and repeated polishing, our molybdenum wafer parts could achieve uniform and defect-free surface.
·All our molybdenum wafer has strict quality control which covers sintering, rolling, forming and surface treatment procedures, Mo parts could meet with ASTM B386 industry standard.
·Extra coating services such as gold coating and silicon carbide coating are available on demand.

Thank you!
At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department. Each production process will test themselves if everything is right. And before shipping, all products will pass the packing department only after inspection department inspected that the products meet customer's requirements. If not, the products will go back to production department for fixing or remaking.
For production, normally our lead time is 20-30 days. But according to different products and different quantity, it changes a little. If your order is emergency, contact with us, we will find a way out to solve your problem. For shipping, normally we ship by express and air. Express takes about 7-10 days, and air 3-5 days. And if customer requires by sea, we will ship by sea, it takes normally 40-50 days.
All our products are shipped after strict inspection and safety packing. Inspection by each production process makes sure the quality is good. And the inspection department will inspect again carefully to make sure everything is right. But if quality issue really occurs, we are sorry, and we will be responsible. To fix the products or remake them, we will make everything right.
In order to keep our healthy cooperation, our payment term normally is 50% payment in advance, balance paid before shipping. And if customer needs, we will calculate the shipping cost for your reference.
