We make the wire other sensor makers rely on

From vacuum melting to ultra-fine drawing, every operation happens under one roof — which is why our EMF output stays consistent batch after batch.

We are a specialist manufacturer of precision thermocouple alloy wire. From vacuum induction melting through multi-pass drawing and 100% electrical testing, every operation happens under one roof — which is why our EMF output stays consistent batch after batch.

Our alloys are supplied to sensor manufacturers, furnace builders and test laboratories across 40+ countries. Each batch ships with a material test certificate carrying a unique furnace number, full chemical composition and EMF calibration data — archived and retrievable by batch number.

01 — Our story
  1. 1998

    Founded as a specialist alloy melting workshop supplying domestic furnace builders.

  2. 2005

    First multi-pass drawing line commissioned; Type K and Type J production begins.

  3. 2011

    ISO 9001 certification; export operations open to Europe and Southeast Asia.

  4. 2016

    Vacuum induction melting installed — composition control to ±0.1%.

  5. 2020

    Diamond-die precision drawing to φ0.025mm for medical and aerospace sensors.

  6. 2024

    Full digital traceability: every spool linked to its furnace number and test record.

02 — How we work

Metallurgy first

We control composition at the melt, not by sorting finished wire. Consistency starts upstream.

Defensible data

Every batch ships with composition, EMF calibration and dimensional records archived for ten years.

Engineer to engineer

Technical questions reach a metallurgist, not a sales script.

03 — Certifications
ISO 9001:2015IEC 60584-1ASTM E230RoHS / REACHSGS & BV inspection
