Applications we support
Tungsten's combination of high density (19.3 g/cm³), extreme melting point (3 422 °C), and hardness makes it indispensable across diamond tooling, electrical, chemical, and drilling industries. The product lines below correspond to the principal application families covered in Jayanth Enterprises India Pvt. Ltd.'s technical brochure.

Diamond tools and core bit
Tungsten metal powder, tungsten carbide powder, and fused tungsten carbide are the key materials behind sintered diamond tooling. Fine WC powder in co-binder matrices forms the cemented carbide segments that hold and expose diamond abrasives in saw blades, core bits, and grinding wheels. Fused W₂C in macro-grit mesh sizes (30/40, 40/60, 60/80) provides the hard matrix for brazed diamond core drill crowns. Fisher sub-sieve grain size selection — typically 1–10 µm for fine tool grades — controls sintered density and binder mean free path, directly affecting tool life and cutting rate.

Diamond tool segments, core bit crowns, diamond saw blades, grinding wheels, abrasive tooling
Electrical contacts & high-density fillers
Tungsten's theoretical density of 19.3 g/cm³ makes it a preferred base for electrical contacts, arc-resistant electrodes, and high-density filler applications. Sintered W-Cu composites formed from tungsten metal powder deliver the combination of electrical conductivity and arc erosion resistance needed in high-current switchgear and circuit breakers. In radiation shielding, fine tungsten powder (-325 mesh, < 44 µm) is blended into polymer matrices to achieve shielding densities that replace lead in medical and industrial applications. Counterbalance and vibration-damping assemblies also rely on tungsten's density where space is constrained.
Relevant products
Use cases
Electrical contacts, arc-erosion electrodes, radiation shielding composites, counterweights, high-density polymer fillers
Tungsten copper for connectors
Tungsten–copper (W-Cu) composites combine tungsten's hardness and heat resistance with copper's electrical and thermal conductivity, making them standard for EDM electrodes, vacuum interrupter contacts, and high-frequency connectors. Common alloy ratios range from 70/30 to 80/20 (W/Cu by weight), tuned to the required hardness and conductivity balance. Tungsten metal powder at the appropriate Fisher grain size is pressed and sintered or infiltrated with copper to achieve near-theoretical density with consistent contact resistance. The resulting contacts withstand repeated arc events and thermal cycling without significant material loss.

Use cases
EDM electrodes, vacuum interrupter contacts, high-frequency connectors, electrical contacts, thermal management substrates
Chemicals & pigments
Sodium tungstate dihydrate (Na₂WO₄·2H₂O, assay ≥ 99%) is supplied as a white crystalline salt for use in inorganic pigment synthesis, fireproofing compounds, corrosion inhibitor formulations, and as a catalyst precursor. Ammonium paratungstate (APT, WO₃ ≥ 88.5% min.) is the primary tungsten intermediate used in the reduction sequence to produce oxides and metal powders; it is also sold directly to chemical processors. Blue tungsten oxide (BTO), yellow tungsten oxide (YTO), and WO₃ are calcination intermediates and direct inputs to catalyst preparation, electrochromic devices, and speciality ceramic pigments. All chemical products are packed to maintain stability against moisture absorption.

Use cases
Inorganic pigments, fireproofing agents, catalysts, corrosion inhibitors, electrochromic coatings, reduction intermediates
Drilling & wear surfacing
Fused tungsten carbide (W₂C) cast rod and crushed macro-grit powders are the standard matrix material for diamond-impregnated core drill crowns used in mineral exploration, geotechnical drilling, and construction core sampling. Grit sizes — typically 30/40, 40/60, and 60/80 mesh — are selected according to the diamond stone size and matrix hardness required by the drill designer. The fused carbide particles, embedded in a copper-silver or bronze brazing alloy, anchor the diamond abrasives and resist erosion during the drilling stroke. WC powder is also used in thermal spray and hard-surfacing welding consumables for wear protection on mining and construction tooling.
