    Tungsten Carbide Grit — Switzerland

    Swiss tunnelling contractors and hard-facing fabricators — supplying the AlpTransit Gotthard AG tunnel construction supply chain, Swiss railway infrastructure maintenance (SBB), and Swiss quarrying and mining equipment repair workshops — use hard-facing tungsten carbide grit (apparent density 5.5–6.0 g/cc, Vickers hardness ~3,000 HV, mesh 30/40 to 100/120) in PTA and OAW hard-facing overlays for TBM disc cutter housings, tunnel boring machine picks, rail head reconditioning, and quarry drill bit shanks operating in Switzerland's extremely hard and abrasive Aar massif granite, Gotthard gneiss, and alpine limestone formations. Switzerland's ongoing investment in tunnelling infrastructure — maintaining the world's most extensive railway tunnel network — creates a technically demanding and consistent market for high-quality hard-facing tungsten carbide grit. Jayanth Tungsten supplies fused W₂C grit via Basel under HS 2849 with full mesh sizing and apparent density documented per lot.

    Export questions

    What hardness can I expect from this grit?

    Hard-facing tungsten carbide grit has an approximate Vickers hardness of 3,000 HV, with apparent density 5.5–6.0 g/cc and total carbon 3.5–4.1%. Mesh fractions from 30/40 to 100/120 are available — confirm your application (overlay, cladding, drill cone) for a mesh recommendation.

    Can you supply ultra-fine tungsten powder for Swiss watchmaking and precision component manufacturing?

    Yes. Jayanth Tungsten supplies W metal powder and WC powder in sub-micron to fine grades (F.S.S.S. 0.8–4 µm) for Swiss precision component and micro-machining applications. Full chemistry CoA (W min. 99.85%, O max. 0.06%, ICP impurity table) is provided per lot. Shipments clear Swiss customs at Basel under HS 8101/2849. Contact us for sample availability.
