About Gan Zhou Pinxin Metal Materials Co., Ltd - Tungsten Products Supplier in China

Gan Zhou Pinxin Metal Materials Co., Ltd is located in China and lists five active products. The catalogue covers tungsten and molybdenum items, including tungsten wire, tungsten bar (HS 8101.94, purity ≥ 99.95 % W), tungsten filament (HS 8101.96, purity ≥ 99.95 % W), evaporation tungsten filament (HS 8101.96, purity ≥ 99.95 % W) and a molybdenum plate (HS 8102.95, purity ≥ 99.9 % Mo). All items fall under the broader HS‑81 chapter for refined copper, nickel and other metals. The supplier classifies the range under Tungsten Products and Metal Products, reflecting the focus on high‑purity refractory metals.

The product count of five indicates a narrow, specialised portfolio rather than a broad line. Tungsten wire is offered without a specific HS code in the supplied data, while the other items are assigned to the 8101 and 8102 HS groups that are commonly used for refined tungsten and molybdenum articles. Material specifications note minimum purity levels of 99.95 % for tungsten and 99.9 % for molybdenum, which align with typical requirements for aerospace, electronics and lighting applications.

Product Range and Specialties of Gan Zhou Pinxin Metal Materials Co., Ltd

Gan Zhou Pinxin lists tungsten wire, tungsten bars, two types of tungsten filaments and a molybdenum plate. In the tungsten market, wire is normally supplied in diameters from 0.1 mm to 3 mm and conforms to ASTM B785 or IEC 60745 standards, with tensile strength often exceeding 1 500 MPa at 99.95 % purity. Tungsten bars are typically produced to ASTM B351 dimensions ranging from 10 mm × 10 mm up to 200 mm × 200 mm, with mechanical properties such as Young’s modulus around 400 GPa. Filaments for vacuum‑evaporation or lighting are graded by filament length (10 - 100 mm), diameter (0.02 - 0.2 mm) and resistance, and are usually inspected to IEC 60745‑2‑1. Molybdenum plates are commonly supplied to ASTM B735 specifications, thicknesses from 0.5 mm to 20 mm, and are valued for a melting point above 2 600 °C and high thermal conductivity.

Trade and Export Information - Gan Zhou Pinxin Metal Materials Co., Ltd

China is a major exporter of refined tungsten and molybdenum, with shipments primarily destined for the United States, Europe, Japan and South Korea where the aerospace, semiconductor and lighting sectors source these refractory metals. The HS‑81.94 and 81.96 codes cover tungsten bars and filaments, while HS‑81.95 applies to molybdenum plates; customs authorities often request a mill test report and material certification to verify purity and alloy composition. Typical export documentation includes a commercial invoice, packing list, certificate of origin and, where required, ISO 9001 or ISO 14001 compliance certificates from the manufacturer. Products are usually packed in wooden crates or steel drums, secured on pallets for 20‑ft or 40‑ft containers, and shipped under FOB or CIF terms. Inspection agencies such as SGS or Bureau Veritas frequently perform pre‑shipment checks for dimensional tolerance, surface finish and purity verification.

Sourcing from Gan Zhou Pinxin Metal Materials Co., Ltd - Buyer Guidance

Buyers sourcing tungsten or molybdenum from Gan Zhou Pinxin should request a recent mill test report that confirms the stated purity (≥ 99.95 % W, ≥ 99.9 % Mo) and provides mechanical property data such as tensile strength and elongation. For wire and filament orders, specifications for diameter, resistance and length should be clarified, and compliance with ASTM B785 or IEC 60745 standards should be verified. It is advisable to obtain a sample batch before full‑scale purchasing, and to confirm packaging details (crate size, moisture barrier) and the agreed Incoterm. Typical minimum order quantities range from 100 kg for wire to 500 kg for bars or plates, with lead times of four to six weeks after order confirmation, subject to material availability and export licensing.

What purity levels are offered for the tungsten products?

The catalogue specifies a minimum purity of 99.95 % tungsten for the bar, filament, evaporation filament and, where applicable, the wire, and 99.9 % molybdenum for the plate.

Which HS codes apply to the listed items?

Tungsten bar is classified under HS 8101.94, tungsten filament and evaporation tungsten filament under HS 8101.96, and the molybdenum plate under HS 8102.95. Tungsten wire falls within the HS 81‑01 family although a sub‑code is not provided.

What industry standards are relevant for these products?

Common standards include ASTM B785 for tungsten wire, ASTM B351 for tungsten bars, IEC 60745‑2‑1 for tungsten filaments, and ASTM B735 for molybdenum plates.

Which certifications should a buyer request?

Buyers should ask for a current mill test report, ISO 9001 quality‑management certification, and any material‑specific test certificates required by the destination market.

What are typical packaging and shipping methods?

Items are usually packed in wooden crates or steel drums, placed on standard pallets, and shipped in 20‑ft or 40‑ft containers under FOB or CIF terms.

What are the usual minimum order quantities and lead times?

Minimum orders are generally around 100 kg for tungsten wire and 500 kg for bars, filaments or molybdenum plates, with lead times of four to six weeks after order confirmation.

How can a buyer obtain a sample?

A buyer can request a sample batch by specifying the exact product, dimensions and required purity; the sample is typically shipped in a small crate together with the corresponding test report.

What documentation is required for customs clearance?

Customs typically requires a commercial invoice, packing list, certificate of origin and the mill test report that confirms material purity and grade.
