    Fused Tungsten Carbide — Japan

    Japanese manufacturers of diamond core bits for geotechnical and civil engineering drilling, and hard-facing electrode producers supplying the construction equipment sector, use fused tungsten carbide (W₂C) grit in crown matrix brazing and overlay welding applications where hardness (~3000 HV), apparent density (5.90 g/cc), and consistent mesh fraction are critical to product performance. Japan's active civil engineering and infrastructure sector — including tunnel boring and foundation drilling operations — drives demand for high-quality diamond core bits and hard-facing consumables. Jayanth Tungsten supplies fused W₂C as crushed grit in ASTM mesh fractions from 30/40 to 100/120 to order, with total carbon (3.5–4.1%) and apparent density confirmed per lot on the certificate of analysis for Japanese drill bit and hard-facing manufacturers.

    Export packaging & documentation

    Fused tungsten carbide is supplied as crushed grit in ASTM/BSS mesh fractions (−40 to +600, to order) or as cast rod, packed in moisture-resistant containers. Export classification is under HS heading 8101.99 (other tungsten articles, fused carbide).

    Shipping to Japan

    Shipments to Japan are routed from Nhava Sheva or Chennai to Yokohama, Tokyo (Keihin), or Osaka (Hanshin) ports, with sea transit typically 10–14 days — one of the shortest export lanes from India to a major tungsten-consuming market. Tungsten powders and carbides are classified under Japan's Customs Tariff Schedule heading 8101; tungstate chemicals under heading 2841. Export documentation is prepared in English with metric units consistent with JIS/ISO standards used by Japanese buyers. Pricing is quoted in JPY or USD on request.

    Export questions

    Which mesh sizes are commonly exported?

    30/40, 40/60, 60/80, and 100/120 ASTM mesh are the most common export grades for diamond tool and hard-facing applications, though the full range from −40 to +600 mesh can be supplied to order.

    Can you supply WC powder meeting Japanese JIS-aligned specifications?

    Yes — our WC powder (F.S.S.S. 2.5–15.0 µm, total C min. 6.11%, free C max. 0.03%) is documented with metric units and ISO-aligned chemistry on each certificate of analysis, consistent with incoming inspection requirements used by Japanese cemented carbide producers. Please share your grade target and application and we will confirm specification alignment and lead time.
