Natural and Artificial Graphite Powder for Lubricant and Refractory
Product Overview
Our high-quality graphite powders are available in both natural flake graphite and artificial graphite grades, with particle sizes ranging from coarse 80 mesh to ultra-fine 5000 mesh. These graphite powders are used as solid lubricants, refractory additives, carbon raisers, foundry coatings, and friction material components. We supply powders with controlled carbon content, ash level, and particle size distribution to meet the exact specifications of lubricant manufacturers, refractory plants, and industrial coating producers.
Graphite powder is a fundamental industrial material used across metallurgy, mechanical engineering, chemicals, and electronics. At Jincheng Graphite, we process both natural flake graphite and calcined artificial graphite into controlled mesh sizes, offering purified and unpurified grades. Our powders are packed in moisture-proof 25 kg bags or jumbo bags, and can be shipped by sea or air to customers worldwide. We also offer custom particle size grinding and classification for specialized applications.

FAQ
Q: What is the difference between natural flake and artificial graphite powder?
A: Natural flake graphite occurs naturally and has superior lubricating properties and flake structure. Artificial graphite powder is made from calcined petroleum coke and has higher purity, more consistent particle shape, and better performance in batteries and conductive applications. The choice depends on your specific application.
Q: Can I get a free sample before ordering?
A: Yes. We provide free 100-500 g samples for quality evaluation. You only cover shipping costs. Please tell us your required mesh size, carbon content, and intended application so we send the right grade.
Q: What is your minimum order quantity?
A: Standard powder orders start from 100 kg. Bulk orders by container load (20-25 MT per 20ft container) receive the most competitive pricing. Contact us for a quotation based on your required quantity.
Q: Can you produce a custom particle size distribution?
A: Yes. We have grinding and classification equipment to produce powders with custom D50 and particle size distributions. Send us your sieve analysis requirement and we will produce a test batch.
