Product Description

Product Description

Molybdenum-copper Crucible

Molybdenum-copper crucibles are high-performance crucibles made from molybdenum-copper alloy. They are not simply a mixture of the two metals, but rather a composite material prepared through special processes such as powder metallurgy infiltration, resulting in a uniform and dense structure. This structure gives them the following properties:

The molybdenum acts as a framework: providing a high melting point, high strength, low thermal expansion coefficient, and good creep resistance.

The copper permeates the network: providing excellent thermal and electrical conductivity, as well as improved machinability.

Product Advantages

The core value of molybdenum-copper crucibles lies in their exceptional "combination of performance" and "design flexibility":

1. Excellent thermal management capabilities:  They possess high thermal conductivity, enabling rapid and uniform heat transfer and preventing localized overheating; simultaneously, they have a low and adjustable coefficient of thermal expansion, allowing for thermal expansion matching with various packaging materials, significantly reducing thermal stress and improving device reliability and lifespan.

2. Superior high-temperature and vacuum performance: Supported by a molybdenum framework, they maintain structural integrity at high temperatures. Their pure material composition results in low volatilization and outgassing in high-temperature vacuum environments, ensuring the cleanliness of the process environment.

3. Good overall mechanical and processing properties: High strength, resistance to ablation, and thermal shock resistance. Compared to pure tungsten-copper alloys, they have lower density and are easier to process, facilitating the manufacturing of complex-shaped components.

4. Flexible performance adjustability: By changing the ratio of molybdenum and copper (e.g., common grades like MoCu10, MoCu20, MoCu40), their thermal conductivity, coefficient of thermal expansion, and strength can be precisely adjusted to meet the specific needs of different applications.

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.
