Product Description
Product Description
Molybdenum Disc
Molybdenum discs, also known as molybdenum pads or molybdenum substrates, are circular thin sheets made from high-purity molybdenum powder through powder metallurgy, followed by rolling, stamping, and precision grinding and polishing. They perfectly inherit the high melting point (2620℃), excellent thermal conductivity, extremely low and adjustable coefficient of thermal expansion, and good high-temperature strength of metallic molybdenum. These properties make them ideal for high-end applications requiring precise thermal management and dimensional stability.

Product Advantages
1. Superior Thermal Management: High thermal conductivity (approximately 140 W/m·K) enables rapid heat transfer, effectively reducing chip junction temperature. Its coefficient of thermal expansion (CTE) is highly compatible with semiconductor materials such as silicon, as well as ceramic packaging shells (e.g., Alumina, AlN), significantly reducing stress caused by thermal cycling, preventing cracking or delamination, and significantly improving device lifespan and reliability.
2. Excellent High-Temperature Stability and Strength: Maintains shape and mechanical properties at high temperatures, resisting creep and deformation, ensuring dimensional accuracy in harsh process environments.
3. High Purity and Cleanliness: High-purity materials ensure no contamination is introduced in semiconductor and vacuum applications. The surface can be mirror-polished (e.g., Ra≤0.4μm), meeting the stringent surface quality requirements of bonding or coating processes.
4. Good Machinability and Metallization: Allows for precision cutting, drilling, nickel/gold plating, and other subsequent processing, facilitating soldering or bonding with chips or other components.

Molybdenum Products: Molybdenum crucibles, molybdenum plates/rods/tubes, molybdenum electrodes, molybdenum screws, molybdenum boats, etc.
Q: What are your advantages compared to your competitors?
A: Our core strengths are:
1.Quality Focus: We maintain strict control from the raw powder stage, ensuring high purity (e.g., above 99.95%) and high density.
2.Technical Team: We have an experienced team of engineers who can provide professional technical selection support.
3.Cost-Effectiveness: As a new company, we offer highly competitive prices without sacrificing product quality.
4.Flexible Customization: We can quickly respond to small-batch, multi-specification customization needs.
Q: How do you guarantee the quality of your products?
A: We implement strict end-to-end quality control:
Raw material testing: We test the purity of incoming tungsten and molybdenum powders.
Process control: There are testing points at key stages such as sintering, rolling, and machining.
Outgoing inspection: Each batch of products undergoes inspection for key indicators such as dimensions, density, and surface finish. We can provide basic outgoing inspection reports.
Q: How do you pack your products to ensure safe transport?
A: We place great importance on product protection. Tungsten and molybdenum products are prone to oxidation and brittleness, so we use vacuum packaging, bubble wrap, and sturdy wooden crates for transportation to ensure the safe arrival of goods.
Q: What should I do if I find a quality problem with the product after receiving it?
A: We offer a quality guarantee. If you find any verifiable product defects upon receiving the goods, please contact us immediately and provide photo/video evidence. Upon confirmation, we will arrange a replacement, refund, or credit against your subsequent order, depending on the circumstances.
Q: Can you provide advice on product use and storage?
A: Of course, here are some general recommendations:
Oxidation Prevention: Tungsten and molybdenum products will oxidize in high-temperature air and must be used under vacuum or inert gas protection.
Prevention of Brittle Fracture: The material is brittle at room temperature; avoid mechanical impact during handling and installation.
Storage: It is recommended to store in a dry, clean environment.
