About Zhuzhou Uko Cemented Carbide Co., Ltd. - Tungsten Products Supplier in China

Zhuzhou Uko Cemented Carbide Co., Ltd. is based in China and currently lists six distinct products. The catalogue spans four top categories: Dies & Mouldings, Tungsten Products, Industrial Rods, and Steel Wires. Within the Tungsten Products segment the company offers drawing dies, strips, heading dies, rollers and rods made from tungsten carbide composites. The Steel Wires entry covers carbon steel grades Q195/Q235 and stainless steel grades 304/316. All items are classified under the relevant HS code families provided in the catalogue.

The heading die is recorded under HS code 8207.40 and is manufactured from tungsten carbide with a cobalt binder. The roller carries HS code 8103.20 and uses a WC‑Co composite typically graded YG8 or YG15 for wear resistance. Steel wires are listed with HS code 7217.10, matching standard carbon and stainless steel wire specifications. The remaining products - drawing die, strip and rods - are described without explicit HS codes but fall within the broader HS chapters for carbide tools and metal rods. The product set therefore provides a compact portfolio of precision tooling and wire materials for industrial applications.

Product Range and Specialties of Zhuzhou Uko Cemented Carbide Co., Ltd.

The supplier’s catalogue includes a tungsten carbide drawing die, a flat strip, a heading die, a roller and solid rods, each fabricated from WC‑Co composites. The heading die uses a cobalt binder ratio typical for hard‑metal tooling, while the roller is specified in grades YG8 or YG15, which correspond to hardness levels around HRA 86‑90 and cobalt contents of 5‑12 %. The rods are offered in standard diameters for industrial machining, and the strip is supplied in widths suitable for stamping operations. Steel wires are offered in carbon steel grades Q195/Q235 and stainless grades 304/316, which meet common tensile strength ranges of 400‑550 MPa for carbon steel and 500‑750 MPa for stainless variants.

In the broader industry, tungsten carbide tooling is commonly referenced against ISO 6507 hardness testing and ASTM B633 grain size classification. Buyers typically look for ISO 9001 quality‑management certification and, for export to the EU, CE marking or RoHS compliance may be required. Steel wires are frequently produced to ASTM A193 or AISI standards, with mill test reports detailing chemical composition and mechanical properties. Standard export packaging for carbide tools includes wooden crates with internal foam inserts, while steel wires are usually bundled in plastic-coated spools and loaded in 20‑ft or 40‑ft containers.

Trade and Export Information - Zhuzhou Uko Cemented Carbide Co., Ltd.

China is a major exporter of tungsten carbide tooling, supplying automotive, aerospace and general machining sectors in Europe, North America and Southeast Asia. The heading die (HS 8207.40) and roller (HS 8103.20) fall under the hard‑metal tool chapter, which often requires importers to present material safety data sheets and conformity certificates such as ISO 9001 or ISO 14001. Steel wires classified under HS 7217.10 are routinely shipped to construction and manufacturing firms, with buyers typically requesting mill test reports and corrosion‑resistance certificates for stainless grades.

Typical incoterms for these categories are FOB Shanghai or CIF destination port, with cargo consolidated in 20‑ft containers (approximately 22‑24 tonnes of carbide tools) or 40‑ft containers for larger wire volumes. Export licensing in China for hard‑metal products may involve compliance with the Ministry of Commerce’s export control lists, and destination countries often inspect incoming shipments against the relevant HS chapters and safety standards.

Sourcing from Zhuzhou Uko Cemented Carbide Co., Ltd. - Buyer Guidance

When sourcing tungsten carbide dies or rollers, request a detailed material test certificate that lists hardness (HRA), cobalt content, grain size and any heat‑treatment parameters. For the steel wires, obtain a mill test report covering chemical composition, tensile strength, elongation and, for stainless grades, pitting‑corrosion resistance data. Verify that the supplier can provide ISO 9001 or ISO 14001 certificates, and ask for sample pieces to confirm dimensions, surface finish and performance before committing to full‑scale production.

Confirm the HS code on the commercial invoice matches the product description (e.g., 8207.40 for heading dies) and that packaging complies with the buyer’s freight forwarder requirements. Typical minimum order quantities range from a few hundred kilograms for specialty carbide tools to one metric ton or more for standard steel wire coils, with lead times of 4‑6 weeks for tooling and 2‑3 weeks for wire, subject to production scheduling and export documentation.

What tungsten carbide products are listed in the catalogue?

The catalogue includes a drawing die, a flat strip, a heading die, a roller and solid rods, all made from WC‑Co composites used for precision forming and machining applications.

Which HS codes are assigned to the heading die and the roller?

The heading die is classified under HS code 8207.40 and the roller under HS code 8103.20, both falling within the hard‑metal tool chapters used for trade reporting.

What grades are typical for the tungsten carbide roller?

Rollers are commonly supplied in grades YG8 or YG15, which correspond to hardness levels around HRA 86‑90 and cobalt binder contents of 5‑12 % for enhanced wear resistance.

What steel grades are available for the steel wires?

Steel wires are offered in carbon steel grades Q195/Q235 and stainless steel grades 304/316, matching standard specifications for construction and manufacturing uses.

Which certifications should a buyer request for these products?

Buyers should request ISO 9001 quality‑management certification, ISO 14001 environmental compliance, and product‑specific test reports such as hardness certificates for carbide and mill test reports for steel wires.

How are the products typically packaged for export?

Carbide tools are usually packed in reinforced wooden crates with foam inserts, while steel wires are coiled on plastic‑coated spools and loaded in standard 20‑ft or 40‑ft containers.

What is the usual lead time for an order of carbide tooling?

Lead time for tungsten carbide dies or rollers is generally 4‑6 weeks, depending on the required grade and any post‑processing heat treatments.

Are sample pieces available for testing before a full order?

The supplier can provide limited sample quantities of each carbide product and wire type, allowing buyers to verify dimensions, hardness and mechanical properties prior to larger purchases.
