Graphite Rod: Types, Uses, and How to Source from China
Graphite rods are essential components in various industries, from metallurgy to electronics. Their unique properties, such as high thermal conductivity and resistance to extreme temperatures, make them indispensable. This guide covers everything from types and features to sourcing tips from China.
How to Find Reliable Graphite Rod from China in 2025
Sourcing graphite rods from China requires careful vetting of suppliers. Look for manufacturers with ISO certifications and positive customer reviews. Platforms like Alibaba and Made-in-China are great starting points. Always request samples to test quality before bulk orders.
What Buyers Should Know Before Buying Graphite Rod from China
Before purchasing, consider factors like lead time, minimum order quantities (MOQs), and shipping costs. Ensure the supplier provides detailed product specifications, including density, purity, and dimensions. Negotiate payment terms to avoid surprises.
Types of Graphite Rod
There are several types of graphite rods, each suited for specific applications:
- Isostatic Graphite Rods: High purity and uniform structure, ideal for semiconductor industries.
- Extruded Graphite Rods: Cost-effective and widely used in general industrial applications.
- Vibrated Graphite Rods: Excellent thermal shock resistance, perfect for foundries.
Functions and Features of Graphite Rod
Graphite rods excel in high-temperature environments due to their low thermal expansion and high conductivity. They are also chemically inert, making them resistant to corrosion. These features make them ideal for use in furnaces, batteries, and electrical discharge machining (EDM).
Scenarios of Graphite Rod
Common applications include:
- Electrodes in EDM processes
- Heating elements in high-temperature furnaces
- Components in lithium-ion batteries
- Thermal management in aerospace
How to Choose Graphite Rod
Selecting the right graphite rod depends on your application. For high-precision tasks, opt for isostatic graphite. For cost-sensitive projects, extruded graphite is a better choice. Always verify the supplier's quality control processes.
Graphite Rod Q & A
Q: What is the typical lead time for graphite rods from China?
A: Lead times vary but usually range from 15-30 days, depending on the order size and customization.
Q: How do I verify the quality of graphite rods?
A: Request third-party lab test reports or conduct your own tests for density, purity, and thermal conductivity.
Q: Are there alternatives to graphite rods?
A: Carbon composites can sometimes substitute, but they lack graphite's thermal and electrical properties.
Q: What's the average lifespan of a graphite rod?
A: Depending on usage, they can last from several months to years in high-temperature applications.
Q: Can graphite rods be recycled?
A: Yes, they can be reprocessed into lower-grade graphite products or other carbon materials.
