tungsten carbide price

Tungsten Carbide price is primarily driven by its Cobalt (Co) content and grain size. Generally, a higher cobalt content (typically 6% to 20%) increases toughness but may lower hardness, affecting the price point. You should request the ISO Grade (e.g., K10, K20, P10) to ensure the material matches your specific application, such as cutting, drilling, or wear parts. Always verify the Hardness (HRA) and Transverse Rupture Strength (TRS); premium prices should reflect high TRS values which indicate better resistance to breakage.

To ensure cost-efficiency, focus on the density (g/cm³) and porosity levels. High-quality Tungsten Carbide should have a density between 14.0 to 15.0 g/cm³ depending on the grade. Lower-priced products often suffer from high porosity (A02, B02 or worse), which leads to premature tool failure. Investing in HIP (Hot Isostatic Pressing) treated carbide may have a higher upfront cost but offers superior structural integrity, reducing long-term replacement costs and downtime.

Suppliers should demonstrate compliance with ISO 9001:2015 for quality management. For environmental and safety compliance, ensure the products meet REACH and RoHS standards, especially if exporting to the EU. Furthermore, because Tungsten is a '3TG' mineral, reputable suppliers on Made-in-China.com should provide a Conflict-Free Mineral Policy to ensure the raw materials are ethically sourced in accordance with international trade regulations.

The price of Tungsten Carbide is highly sensitive to the APT (Ammonium Paratungstate) market index. To mitigate risk, consider long-term framework agreements with price adjustment clauses or bulk purchasing when market rates are low. Always monitor the China Tungsten Industry Association (CTIA) reports, as China controls a majority of the global supply, significantly influencing international pricing.

Tungsten Carbide is extremely heavy and brittle. Ensure the supplier uses reinforced wooden crates with internal anti-collision padding and vacuum-sealed plastic packaging to prevent oxidation during sea freight. For shipping from China, FOB (Free On Board) is often preferred for large volumes to maintain control over freight costs, while DDP (Delivered Duty Paid) via specialized logistics providers on Made-in-China.com can simplify customs clearance for smaller batches.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payments until the goods are received. Before finalizing a large contract, request a Third-Party Inspection (such as SGS or Bureau Veritas) to conduct a pre-shipment audit. This audit should specifically check for dimensional tolerances (using micrometers) and material composition (via XRF analysis) to ensure the delivered goods match the paid-for specifications.
