Yg6 carbide tips price

YG6 carbide belongs to the Tungsten-Cobalt (WC-Co) category, containing 6% Cobalt content and 94% Tungsten Carbide. It is characterized by high wear resistance and moderate toughness. Key benchmarks include a hardness of ≥89.5 HRA and a transverse rupture strength of approximately 1900-2100 MPa. It is primarily used for semi-finishing and finishing of cast iron, non-ferrous metals, and non-metallic materials at medium cutting speeds.

Buyers should prioritize suppliers who provide ISO 9001 certification and detailed Material Test Reports (MTR). Ensure the tips undergo HIP (Hot Isostatic Pressing) sintering to eliminate internal porosity, which significantly improves durability. For international compliance, verify that the products meet GB/T 3301 standards (or equivalent ISO standards for carbide grades) and ensure the supplier can provide SGS or TUV inspection reports upon request.

The price is primarily driven by the current market price of Tungsten (APT) and Cobalt powder. Additionally, geometric complexity (standard vs. custom shapes) and surface treatment (such as CVD or PVD coating) will impact the unit cost. For bulk procurement, buyers can typically expect a 10-20% price reduction when ordering in quantities exceeding 50kg to 100kg, as manufacturing efficiency increases with volume.

YG6 tips are widely used in woodworking tools, stone cutting saws, and metal machining inserts. When sourcing, you must confirm dimensional tolerances (typically ±0.5mm for as-sintered) and brazing compatibility. If the tips are for automated CNC lines, specify ground finishes to ensure precise tool-holder fitment and reduced vibration during high-speed operations.

The most significant risk is material grade substitution, where a supplier might provide a lower-grade recycled powder instead of virgin YG6. To mitigate this, request a pre-shipment sample for hardness and density testing. Another risk is shipping damage; since carbide is brittle, ensure the supplier uses vacuum-sealed plastic packaging and reinforced wooden crates to prevent chipping during transit.

Utilize professional sourcing platforms like Made-in-China.com, which offers Audit Reports and Verified Supplier statuses. Always use Secure Payment services that hold funds in escrow until shipping documents are verified. For large-scale contracts, include a quality claim clause that allows for returns or discounts if the HRA hardness deviates by more than 0.5 from the agreed specification.

Carbide tips are heavy but low-volume, making sea freight (LCL) the most economical for bulk, while air express (DHL/FedEx) is better for urgent samples. Be aware of the HS Code (typically 8209.00) to determine import duties in your country. Ensure the Commercial Invoice clearly states the chemical composition to avoid delays during customs inspections related to strategic metal regulations.

Negotiate based on Total Weight rather than just unit price, as raw material costs are calculated by the kilo. Ask for tiered pricing (e.g., 10kg, 50kg, 200kg) and inquire if the supplier offers blank (un-ground) tips if you have in-house grinding capabilities, which can save 15-25% in costs. Establishing a long-term supply agreement can also hedge against the volatility of raw tungsten prices.
