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

Zhuzhou Goode Tungsten Carbide Co., Ltd is based in China and currently lists five distinct tungsten‑based products. The catalogue is organised under the Tungsten Products category and includes tungsten heavy alloy balls, tungsten heavy alloy cubes, tungsten carbide rods, tungsten carbide bars, and tungsten carbide wire‑drawing dies. The heavy alloy items are made from high‑density tungsten‑cobalt alloys, while the carbide items are cemented tungsten carbide (WC‑Co) materials. Two of the items carry specific customs classifications: the bars are recorded under HS code 8103.20 and the wire‑drawing dies under HS code 8205.59. The supplier is classified as an imported tier with a harbor trust rating.

Product Range and Specialties of Zhuzhou Goode Tungsten Carbide Co., Ltd

The product list covers standard forms used in precision engineering: spherical balls and cubic blocks of tungsten heavy alloy, cylindrical rods of cemented carbide, rectangular bars of WC‑Co, and specialised dies for wire drawing. In the industry, tungsten heavy alloy balls typically contain 93‑95 % tungsten, have a density of about 17 g/cm³ and are offered in diameters from 2 mm to 30 mm, while cubes are supplied in 10 mm to 50 mm edges with similar purity levels. Tungsten carbide rods and bars are commonly produced with WC content of 90‑95 % and a cobalt binder of 5‑10 %, achieving hardness values of 1400‑1500 HV and tensile strengths above 1500 MPa. Wire‑drawing dies are machined to tight dimensional tolerances (±0.02 mm) and are often coated to reduce wear. Buyers usually request compliance with ASTM B352 for carbide bars and ISO 9001 quality‑system certification for the manufacturing process.

Trade and Export Information - Zhuzhou Goode Tungsten Carbide Co., Ltd

China is a major exporter of tungsten and cemented carbide products, supplying automotive, aerospace, and tooling sectors worldwide. HS chapter 81 items such as cemented carbide bars (8103.20) and HS chapter 82 items like carbide dies (8205.59) are subject to standard customs duties and often require a certificate of origin, a mill test report, and a declaration of cobalt content for regulatory compliance. Typical import markets include the European Union, the United States, Japan, and South Korea, where buyers commonly require ISO 9001, ISO 14001, and ASTM certifications, as well as CE marking for equipment‑integrated components. Shipping is usually arranged in 20 ft or 40 ft containers, with pallets or wooden crates fitted with moisture‑resistant liners, and Incoterms such as FOB Shanghai or CIF Hamburg are frequently used.

Sourcing from Zhuzhou Goode Tungsten Carbide Co., Ltd - Buyer Guidance

Prospective buyers should request a recent mill test report that details chemical composition, WC‑Co ratio, hardness, and tensile strength for each product batch. A certificate of analysis, compliance with relevant ASTM or ISO standards, and a certificate of origin are standard documents for customs clearance and quality verification. Verify that the supplier can provide samples that meet the specified dimensional tolerances and material grades before confirming larger orders.

What tungsten products are listed by Zhuzhou Goode Tungsten Carbide Co., Ltd?

The catalogue includes tungsten heavy alloy balls, tungsten heavy alloy cubes, tungsten carbide rods, tungsten carbide bars (HS 8103.20) and tungsten carbide wire‑drawing dies (HS 8205.59). All items are manufactured from either high‑density tungsten‑cobalt alloys or cemented WC‑Co carbide.

What are the typical specifications for the tungsten carbide bars?

Bars are generally cemented carbide with 90‑95 % WC and 5‑10 % cobalt binder, achieving hardness of 1400‑1500 HV and tensile strength above 1500 MPa. Standard lengths are 6 m with a tolerance of ±0.2 mm, and buyers often require an ASTM B352 compliance certificate and a mill test report.

What size range is offered for the tungsten heavy alloy balls?

Balls are produced in diameters from 2 mm up to 30 mm, with a density around 17 g/cm³ and purity exceeding 99.5 % tungsten. Dimensional tolerance is typically ±0.01 mm, and a material test certificate is provided for each batch.

Which documents should a buyer request before purchasing?

Buyers should request a mill test report, chemical composition analysis, hardness test results, an ISO 9001 quality‑system certificate, a certificate of origin, and a certificate of analysis matching the HS code.

How are the products packaged for export?

Products are packed in moisture‑resistant wooden crates or steel drums, each clearly labelled with the HS code, net weight, and material description. Containers of 20 ft or 40 ft are commonly used, and shipping terms such as FOB Shanghai or CIF destination are typical.

What are the usual minimum order quantities and lead times?

Minimum orders are typically 2 tonnes for rods and 5 tonnes for bars, while balls and cubes can be ordered in 1 tonne batches. Lead time after order confirmation and receipt of test reports is usually 4‑6 weeks.

Which global regions most frequently import these tungsten products?

Key import regions include Europe (especially Germany and the UK), North America (United States and Canada), and East Asia (Japan and South Korea). These markets mainly use the products for automotive components, aerospace parts, precision tooling and high‑performance cutting applications.

What certifications are commonly required for tungsten carbide components?

Typical certifications include ISO 9001 for quality management, ISO 14001 for environmental management, ASTM B352 for cemented carbide bars, and compliance with CE marking where the components are integrated into regulated equipment.
