Most of our competitors make cables, brass rods and copper tube as well. We don’t.
Nav Jyoti Metals has made one thing since 1993 — winding wire. Enamelled and paper insulated, copper and aluminium, round and rectangular. Every machine we have bought, every process we have refined and every person we have trained has gone into that single product family.
Our metal comes from Hindalco, Sterlite, Hindustan Copper and NSIC. We name them because we think you should know.

Why us — with the evidence
Four claims you can check.
02Dedicated lines per metal
Extruded strip
Separate extrusion lines for copper and aluminium — no cross-contamination. Exact section, spool weights built to your requirement rather than to standard sizes, and elongation and tensile passing as-extruded.
2 dedicated extrusion lines
03Purpose-built ERP
Traceable
Every enquiry, job card, batch and despatch runs through a system we built ourselves. Ask what happened on any order and there is a record — not a memory. Rare in this industry, and the answer to the question every overseas buyer is really asking.
100% of orders system-tracked
04Published methods
Tested
Breakdown voltage, pinhole, springback, adhesion, elongation and cut-through — tested in our own lab, against IEC and IS methods, with the results written down and shared.
Test methods published in full

Enquire
Tell us the specification, not just your phone number.
Conductor, insulation, class, grade, size, quantity and application. Give us those and you get a real answer from someone who understands the question — not a call asking what you need.
Every enquiry lands directly in our production system. Nothing gets lost on a notepad.
Placeholder
The multi-step RFQ goes here — conductor and form, then class, grade and size, then quantity, packing and destination, then contact details with optional drawing upload. It posts straight into the ERP with the UTM and landing page attached.
