Advantages Over Competing Materials
Durability
Compared to graphite or tungsten, the molybdenum wafer offers better oxidation resistance and mechanical strength at elevated temperatures.
Cost Efficiency
While tungsten has a higher melting point, molybdenum provides a more cost-effective solution for applications below 1,900°C.
Machinability
The molybdenum disk can be precision-machined into complex shapes without compromising structural integrity.
Surface Quality
The mirror polished moly wafer outperforms standard polished metals in minimizing surface defects and contamination risks.
Packaging & Handling Guidelines
Each molybdenum disc is individually sealed in vacuum anti-static packaging to prevent oxidation and scratches. For mirror polished Mo wafer, we will pack them in a 4” cassette every 25pcs, and then vacuum the cassette.
Storage: Keep in a dry, room-temperature environment. Avoid exposure to humid or acidic atmospheres.
Cleaning: Use alcohol or acetone for surface degreasing; avoid abrasive materials.

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.
