Compound Carbide Powder
The product offered by Changsha Langfeng Metallic Material Co., Ltd. is a dual‑carbide Compound Carbide Powder supplied in two grades, (Ti,Ta)C and (W,Ta)C55. The (Ti,Ta)C grade contains 35.0 % Ti, 3.0 % Ta, 12.0 % total carbon and 0.20 % free carbon, while the (W,Ta)C55 grade is composed of 47.0 % W, 46.8 % Ta, 6.15 % carbon and 0.15 % free carbon, as detailed in the supplier’s composition table. Particle size distribution ranges from 0.5 µm to 500 µm, corresponding to 5‑400 mesh, and the powder can be custom‑graded on request. Impurity limits are listed at Fe ≤0.05 %, Si ≤0.10 %, Al ≤0.01 %, O ≤0.30 % and other trace elements are kept below 0.01 %.
These grades are recognised for their low impurity profile, which supports consistent sintering behaviour in powder‑metallurgy processes. Typical bulk density for carbide powders of this composition lies around 7.5 g cm⁻³, providing good flowability for pressing operations. Standard sintering temperatures for cemented‑carbide production are in the 1400‑1500 °C range, where the controlled Ti/Ta or W/Ta ratios yield predictable hardness and wear resistance. In the industry, a D50 particle size of approximately 20 µm is common, and the resulting sintered material can achieve hardness values near 1500 HV.
The powder is primarily used by manufacturers of cemented‑carbide cutting tools, mining drill bits and wear‑resistant components. Importers should confirm the supplier’s minimum order quantity, lead time, and preferred Incoterms directly with Changsha Langfeng Metallic Material Co., Ltd., as these details are not disclosed in the listing. Payment terms are typically negotiated on a case‑by‑case basis and may include T/T or L/C, subject to mutual agreement.
| Grade (Ti,Ta)C | Ti 35.0 % ±0.55 %, Ta 3.0 % ±0.5 %, Total C 12.0 % ±0.2 % |
| Grade (W,Ta)C55 | W 47.0 % ±0.5 %, Ta 46.8 % ±0.5 %, Total C 6.15 % ±0.2 % |
| Particle size | 0.5‑500 µm (5‑400 mesh) |
| Total carbon | 0.20 % (Ti,Ta)C, 0.15 % (W,Ta)C55 |
| Free carbon | 0.06 % (both grades) |

Changsha Langfeng Metallic Material Co., Ltd. is located at Tianxiong Road 98, Furong Area, Changsha, Hunan 410100, China. The company is classified as an imported‑tier supplier and carries a harbor trust tier, indicating a basic level of verification on the platform. Its response metrics show a 0 % response rate and no recorded response time, suggesting that inquiries may require follow‑up. The firm specialises in providing high‑performance carbide powders for industrial metallurgy.
The listing details the chemical composition and particle‑size options but does not disclose MOQ, price, lead‑time or specific certification status. Potential buyers should request a material safety data sheet and a recent assay report to confirm the stated impurity limits. As the supplier does not publish its production capacity, importers may wish to discuss batch size feasibility during negotiations. All communications should reference the exact grades (Ti,Ta)C and (W,Ta)C55 to ensure the correct material is supplied.
Compound Carbide Powder is a high-performance dual-carbide material available in (Ti,Ta)C and (W,Ta)C55 grades, designed for cemented carbide and cutting tool manufacturing. These grades offer precise control of Ti/Ta and W/Ta ratios with total carbon and free carbon levels carefully managed to ensure consistent sintering behavior. Low impurity levels (Fe, Si, Al, O, N, Na, K, Ca, S) make these powders suitable for precision machining, mining tools, and wear-resistant applications in industrial settings. Widely traded as a raw material input for powder metallurgy and advanced manufacturing processes.

Sourcing Compound Carbide Powder from Changsha Langfeng Metallic Material Co., Ltd. - China Import Guide
Before placing an order, verify that the supplied grades match the required Ti/Ta or W/Ta ratios and that the impurity limits meet your quality standards. Request a recent assay report and, if possible, a small trial batch to evaluate sintering behaviour. Confirm that the particle‑size distribution aligns with your pressing equipment, and ask whether the supplier can provide a material safety data sheet.
Discuss logistics early, as the supplier has not published lead‑time or preferred Incoterms. Typical arrangements for bulk ceramic powders involve CIF or FOB shipping from the port of Shanghai, but you should obtain the exact terms from Changsha Langfeng Metallic Material Co., Ltd. Payment is usually negotiated per transaction and may include telegraphic transfer (T/T) or a letter of credit (L/C) once the contract is finalised.
Arrange an independent inspection of the powder before shipment, focusing on particle‑size analysis, chemical composition and bulk density. Inspection agencies can perform X‑ray fluorescence (XRF) and laser diffraction testing to confirm the supplier’s claims. Ensure that the supplier provides a certificate of analysis and any required customs documentation, such as a material safety data sheet and import permit.
