Titanium carbide

When purchasing Titanium Carbide (TiC), the most critical factors are purity levels (typically 99% to 99.9%), particle size distribution (measured in microns or nanometers), and combined carbon content. For high-performance applications like cermets or cutting tools, ensure the free carbon content is kept to a minimum (usually <0.5%) to prevent structural weaknesses. Additionally, verify the crystal structure via X-ray diffraction (XRD) to ensure a high degree of carbonization.

Titanium Carbide is primarily used in the production of cermets and cemented carbides for high-speed cutting tools, wear-resistant coatings for aerospace components, and as an additive in steel manufacturing to improve hardness. It is also increasingly used in thermal spray powders and electronic materials due to its high melting point (3,140°C) and excellent thermal conductivity.

As a chemical product, TiC must be accompanied by a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) compliant with the Globally Harmonized System (GHS). For shipments to the EU, ensure REACH registration compliance. Because it is often transported as a fine powder, it may be classified under UN3178 (Flammable solid, inorganic) depending on particle size, requiring specific hazardous goods packaging and labeling.

Buyers should request a Certificate of Analysis (COA) for every batch. It is highly recommended to use third-party inspection services (such as SGS or Intertek) to perform Scanning Electron Microscopy (SEM) to check particle morphology and Laser Diffraction for particle size analysis. Requesting a pre-shipment sample (50g-100g) for lab testing is a standard industry practice to ensure the material meets your specific sintering requirements.

The primary risks include quality inconsistency between batches, moisture absorption during sea freight if packaging is not vacuum-sealed, and customs delays due to improper chemical classification. To mitigate these, always use vacuum-sealed aluminum foil bags inside reinforced drums and ensure the HS Code (typically 2849.90) is correctly declared to avoid tariff penalties.

Focus negotiations on purity-to-price ratios rather than just the lowest unit cost. Ask for tiered pricing based on volume (e.g., 100kg vs. 1 ton) and negotiate payment terms like 30% deposit and 70% against the Bill of Lading (B/L). For long-term cooperation, seek a price-lock agreement to protect against fluctuations in the raw material costs of titanium and carbon.

Utilize Trade Assurance services on Made-in-China.com to protect your payment until delivery is confirmed. For logistics, choose freight forwarders experienced in handling Class 4.1 flammable solids if the powder is fine. Ensure the incoterms are clearly defined; FOB (Free On Board) is preferred for buyers who want control over shipping costs, while CIF (Cost, Insurance, and Freight) is better for those who want the supplier to handle the risks of transit to the destination port.
