Import Dolomite — Buy in wholesale FOB from Supplier in China

Dolomite from Daye Jinpeng Friction Material Co. Ltd. is a white to pinkish powdered mineral composed of calcium magnesium carbonate, with a chemical formula of CaCO3·MgCO3. The material is processed from crushed dolomite ore and sieved to a minimum grade of 200 mesh, with 97% passing through 325 mesh. Its density ranges from 2.8 to 2.9 g/cm³ and its Mohs hardness is between 4.0 and 4.5. This product is not a generic filler but a functional ingredient engineered for friction applications, particularly in brake pads and clutch linings where it stabilizes friction coefficients and reduces wear.

The material contains 33.96% CaO and 22% min MgO, with trace impurities including 1.10% SiO2, 0.23% Fe2O3, and 0.04% Al2O3. These values reflect a controlled industrial-grade composition suitable for high-temperature environments. Dolomite decomposes between 700°C and 900°C into calcium oxide and magnesium oxide, making it effective as a flux in metallurgical processes. It is also used in ceramics and cement production where its thermal stability and low reactivity with binders are valued. The powder is typically packaged in bulk or jumbo bags to prevent contamination and moisture absorption during transit.

End-users include manufacturers of automotive friction components, steel mills, and industrial ceramic producers. Buyers in these sectors source this material for its consistent particle size distribution and low impurity profile, which directly impact brake performance and furnace efficiency. The product is supplied in standard bulk quantities with no fixed MOQ stated; lead time and incoterms must be confirmed directly with the supplier. Packaging is designed for industrial handling, and the material is not certified for food or pharmaceutical use.

Daye Jinpeng Friction Material Co. Ltd. is a manufacturer based in Daye City, Hubei Province, China, with a physical address in Sidouliang Village, Jinhu Street. The company specializes in mineral-based friction materials and processes dolomite ore into fine powders for industrial applications. There is no public data on company size, revenue, or years in operation. The supplier is verified as a harbor-tier entity on the platform, indicating basic compliance with registration and documentation standards, but no third-party certifications or production audits are disclosed.

The listing does not claim export experience, client names, or production capacity. The supplier's focus appears to be on the technical refinement of dolomite for friction components rather than bulk commodity sales. There is no evidence of agricultural or cement-grade offerings. Response rate and average response time are not tracked, suggesting limited engagement with buyers outside direct inquiries. Buyers should treat this as a direct manufacturer with no stated distribution network.
