Tungsten carbide rollers price

When sourcing Tungsten Carbide Rollers, you must prioritize Grade Selection (Cobalt content vs. Nickel binder). For high-wear applications, a Cobalt binder (6% to 25%) is standard, while Nickel binders offer superior corrosion resistance. Ensure the Hardness (HRA) ranges between 85 and 92 depending on the specific rolling task. Additionally, verify the Surface Roughness (Ra); high-precision rollers should achieve a mirror finish (Ra < 0.05 μm) to prevent marking the processed material.

Professional B2B buyers should demand ISO 9001:2015 certification for the manufacturing process. For the material itself, request a Metallographic Analysis Report to check for porosity (A02, B02, C02 levels) and grain size uniformity. If the rollers are used in food-grade packaging or sensitive environments, ensure compliance with REACH or RoHS standards to guarantee the absence of hazardous heavy metals.

The price is primarily driven by Tungsten powder market rates and the complexity of the sintering process (HIP - Hot Isostatic Pressing). While the initial cost is higher than steel rollers, the Total Cost of Ownership (TCO) is lower due to a service life 10 to 20 times longer. Look for suppliers on Made-in-China.com who offer re-grinding services, which can extend the product lifecycle and improve long-term ROI.

Tungsten Carbide Rollers are essential in Cold Rolling for ribbed wires, High-speed Wire Rod Mills, and Flattening/Shaping of non-ferrous metals. For stretch-reducing mills, ensure the rollers have high thermal fatigue resistance to withstand rapid temperature fluctuations during continuous operation.

Always utilize Trade Assurance services provided by platforms like Made-in-China.com to protect your payment. Before shipping, hire a third-party inspection agency (such as SGS or Bureau Veritas) to perform a Non-Destructive Test (NDT), specifically Ultrasonic Testing, to detect internal cracks or voids that are not visible to the naked eye.

Focus on Volume-Based Pricing; most manufacturers offer significant discounts for orders exceeding 50-100 units. Negotiate for customized packaging (e.g., vacuum-sealed anti-rust paper and reinforced wooden crates) to be included in the FOB price, as these heavy items are prone to oxidation and impact damage during sea freight.

Due to the high density and weight of Tungsten Carbide, Sea Freight (LCL or FCL) is the most cost-effective for bulk orders. However, for urgent replacement parts, Air Freight is viable but requires specialized heavy-duty cushioning. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and follows International Standards for Phytosanitary Measures (ISPM 15) for wooden pallets to avoid customs delays.

Verify the HS Code (typically 8455.90 or 8207.30) with your local customs broker to determine the exact Import Duties and Anti-Dumping duties. Some regions have specific trade barriers on Chinese steel and carbide products; ensure your supplier provides a Certificate of Origin (CO) to potentially benefit from preferential trade agreements.
