Product Name: Mirror Polished moly wafer disc Molybdenum Wafer Molybdenum Disc
Our mirror polished molybdenum wafer is engineered for applications demanding superior surface finish, high temperature resistance and corrosion resistance. Manufactured from high-purity molybdenum plate via punching and professional polishing processes ect., it 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. We will report more information after customer's feedback.
Core Features of molybdenum disk
1. Ultra-smooth Surface: Mirror polishing ensures surface roughness Ra ≤0.02㎛. It has low light scattering and high reflectivity, ideal for optical and semiconductor applications.
2. Outstanding High Temperature Resistance: Stably withstands temperature up to 2000℃ (3632℉) under vacuum or inert gas atmosphere. Low thermal expansion rate maintains stable dimension amid temperature changes.
3. Strong Corrosion Resistance: Molybdenum parts resists erosion from acid, alkali and molten metal, securing long service life in harsh working conditions.
4. Customized Dimensions Available: normally molybdenum wafer diameter: 10mm~500mm, thickness: 0.1mm~20mm. Dimensional tolerance reaches ±0.005mm, other customized sizes are acceptable.
5. High Material Purity: Molybdenum wafer components purity ≥99.95%.

Mirror polished Mo disc wafer Advantages Compared with Other Materials:
·Durability: molybdenum parts has better high-temperature oxidation resistance and mechanical strength than graphite and tungsten materials.
·Cost Efficiency: More cost-effective than tungsten when working temperature is below 1900°C.
·Fine Machinability: Can be processed into complex shapes without losing structural strength.
Premium Surface Quality: Fewer surface defects and lower contamination risk than ordinary polished metal products.
Molybdenum wafer disc testing & packaging:
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.
Reasons to Choose Our Mirror Polished Molybdenum Wafer:

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.
