| High-density isostatic pressing graphite (domestic production) | 99.5% | 200 - 500 | Ceramic hot pressing molding, hard alloy sintering |
| Superfine particle isostatic pressed graphite (domestic product) | 99.99% | 500 - 1,200 | Precision ceramics, electronic ceramics, new energy materials |
| Imported high-end graphite (such as Messner, SGL) | 99.995%+ | 1,200 - 2,600 | Aviation, semiconductors, medical precision ceramics |
Purchase Suggestions
Select based on requirements: For general applications, choose domestic high-density isostatic graphite (99.95%), which offers the highest cost-effectiveness
Batch purchase: Discounts of 10-15% are available for orders over 10 pieces. Negotiable for more favorable prices for long-term cooperation
Customization: Providing detailed drawings can reduce design costs and prevent rework due to communication errors
Cost control: The mold can last for 500-800 furnaces. Consider the overall cost-effectiveness rather than just the unit price
Prices will be adjusted based on factors such as raw material market fluctuations and processing technology upgrades. It is recommended to inquire and compare prices from multiple suppliers before purchasing.
The actual measurement data shows that our high-density graphite blocks perform exceptionally well in continuous thermal cycling: the thermal expansion coefficient is only 0.022×10⁻⁶/℃ (the industry average is 0.035×10⁻⁶/℃), and the service life exceeds 1,000 cycles (competitors typically have 500-700 cycles). In the field of new energy, such as in the melting of lithium-ion battery electrodes, this product can reduce the risk of component segregation by 35% and directly increase the battery cycle life by 20%. This performance advantage stems from our unique micro-pore structure optimization process, which ensures that the graphite blocks maintain high precision during repeated melting, especially suitable for precise processing in vacuum furnaces and high stability requirements in the electronics industry.
We are always at your service when you need
As a raw material factory, we have established long-term strategic cooperation with international giants such as Siemens from Germany, TSMC from the United States, and Panasonic from Japan, serving customers in over 50 countries worldwide. Through a direct supply chain model, we eliminate intermediate links and achieve price advantages: 15-20% lower than mainstream suppliers in the market. At the same time, the material purity reaches 99.999% (without metal impurities), far exceeding industry standards (99.99%). Each batch of products is certified by ISO 9001 and provides full traceability of quality, ensuring more frequent and better material usage in scenarios such as semiconductors and vacuum furnaces.
