These circular blades are produced from tungsten carbide (WC‑Co) with typical grades YG8 or YG6X, delivering a hardness that exceeds HRA 90. The catalogue lists sizes such as 100 mm × 15 mm × 0.35 mm and 60 mm × 19 mm × 0.3 mm, each offering a precise diameter, width and thickness for high‑speed slitting applications.
Tungsten carbide provides exceptional wear resistance, allowing the blades to maintain a sharp edge in continuous operation on rubber, filter media, corrugated paper, textile and film materials. Industry standards usually call for a diameter tolerance of ±0.02 mm and a surface finish that supports low‑vibration cutting; no additional coating is applied, relying on the intrinsic hardness of the carbide matrix.
The blades are suited for slitting, shearing and trimming processes in packaging, paper, textile and metal‑processing plants. Typical buyers include equipment manufacturers, large‑scale converters and industrial distributors who need reliable replacement parts. The listing does not disclose MOQ, pricing or lead time, so prospective importers should confirm those parameters directly with the supplier.

When evaluating a purchase, confirm the exact grade (YG8 or YG6X) and verify the diameter, width and thickness for the specific size you require. Ask for a hardness test report and a dimensional inspection certificate to ensure the blades meet the ±0.02 mm tolerance needed for your slitting line.
Clarify the preferred Incoterms, for example FOB Nanjing or CIF Shanghai, and agree on payment terms before finalising the order. Because the supplier’s response rate is shown as zero, it is prudent to establish a direct point of contact and obtain a written quotation that includes lead time and any minimum order quantity.
Arrange an independent factory audit or third‑party inspection to check for material consistency, surface finish and absence of coating. Request a conformity declaration or test report for each shipment to streamline customs clearance and guarantee the performance of the blades in your production environment.
