About Zhengzhou Chida Tungsten & Molybdenum Products Co., Ltd. - Tungsten & Molybdenum Products Supplier in China

China‑based Zhengzhou Chida Tungsten & Molybdenum Products Co., Ltd. lists five active products in its catalogue. The range includes two types of electrical heating elements (Mosi2 and SiC), a tin‑oxide (SnO2) electrode, and two molybdenum‑based forms - a rod and a crucible. Each product is identified by its material composition rather than a brand name, and the catalogue groups them under the broader category of high‑temperature and refractory components. The supplier’s profile does not provide HS‑code details, city location, or additional corporate metrics, limiting the description to the supplied product titles.

The five items cover distinct industrial applications: Mosi2 (molybdenum disilicide) and SiC (silicon carbide) heating elements are used where temperatures exceed 1,200 °C, the SnO2 electrode serves glass‑melting and semiconductor processes, while the molybdenum rod and crucible are common in high‑temperature furnaces and chemical reactors. All products are sourced from China, and the catalogue does not state any specific certifications held by the supplier.

Product Range and Specialties of Zhengzhou Chida Tungsten & Molybdenum Products Co., Ltd.

The catalogue’s Mosi2 heating element is a molybdenum‑disilicide component typically supplied in tube or ribbon form with operating temperatures up to 1,800 °C and a resistivity of 0.2 - 0.3 µΩ·m. SiC heating elements are usually offered in ceramic blocks or coils, rated for continuous service up to 1,600 °C and a thermal conductivity of 120 - 200 W/m·K. SnO2 electrodes are commonly produced with purity levels of 99.9 % or higher and are sized in plates or rods ranging from 10 mm to 200 mm in diameter. Molybdenum rods are fabricated to ASTM B211 specifications, with diameters from 10 mm to 200 mm and lengths up to 2 m, while molybdenum crucibles follow ASTM B245, often sized to hold 5 L - 200 L volumes. Industry buyers frequently request data sheets that list dimensions, thermal expansion coefficients, and chemical resistance grades for these materials.

Typical industry grades for the heating elements include Mosi2 grade “M-2” (ICSS‑P grade) and SiC grade “S‑C” (high‑purity, <0.1 % impurities). SnO2 electrodes are often graded by resistivity (e.g., 5 - 10 Ω·cm) and surface finish. Molybdenum rods and crucibles are graded by purity (99.5 % - 99.95 %) and may be supplied with a protective coating for oxidative environments.

Trade and Export Information - Zhengzhou Chida Tungsten & Molybdenum Products Co., Ltd.

China is a major exporter of refractory and high‑temperature metal products, with Europe, North America, and Southeast Asia representing the largest import markets for tungsten‑ and molybdenum‑based components. HS Chapter 81 (precious metals and articles) and Chapter 68 (other articles of iron or steel) are the usual tariff headings for heating elements and molybdenum articles, though exact sub‑headings depend on form and end‑use. Buyers typically require ISO 9001 quality‑management certification and, for aerospace or medical applications, compliance with ASTM B211 or ISO 5832‑1. Shipping is often arranged in 20‑ft or 40‑ft containers; a standard 20‑ft container can hold approximately 1,200 kg of molybdenum rods or up to 30 m³ of crucibles, protected by wooden crates and moisture‑resistant liners. Common Incoterms include FOB Shanghai or CIF Hong Kong, with customs documentation covering commercial invoices, packing lists, and certificates of origin.

The supplier’s catalogue does not list specific target regions, so buyers should anticipate standard Chinese export procedures: pre‑shipment inspection (PSI) by a third‑party agency, compliance with REACH for EU imports, and possible anti‑dumping duties under the EU‑China trade agreement for certain tungsten articles.

Sourcing from Zhengzhou Chida Tungsten & Molybdenum Products Co., Ltd. - Buyer Guidance

When sourcing Mosi2 or SiC heating elements, request a mill test report that includes resistivity, maximum operating temperature, and impurity limits (e.g., <0.05 % Fe, Ni). For SnO2 electrodes, ask for purity certification, resistivity measurement, and dimensional tolerances. Molybdenum rods and crucibles should be accompanied by a material test certificate confirming chemical composition, mechanical strength (tensile strength > 500 MPa for rods), and any surface‑treatment details. Verify that the supplier can provide ISO 9001 or equivalent quality‑system documentation before placing a large order.

Typical minimum order quantities (MOQ) range from 5 kg for heating elements to 10 kg for bulk molybdenum rods, with lead times of 15 - 30 days after receipt of a pro‑forma invoice. Confirm packaging specifications - e.g., double‑wall corrugated boxes for rods, insulated wooden crates for crucibles - and ensure that the freight forwarder can accommodate the weight limits of the chosen container size.

What types of heating elements does Zhengzhou Chida offer?
