Pgm wire
A combination of experience and continuous innovation yields quality, reliability and precision. That is why our platinum group metal (pgm) wires are used in critical applications such as airbag initiators, gas sensors and turbine blade casting. And our range of wires can be manufactured to meet the exact needs of your application.
All wires are available in straight lengths, cut pins or on a wide range of spools. Precise hardness, tensile properties, elongations or resistances can be supplied according to required specifications.

Ultrafine wire
We're expert manufacturers of ultrafine wire (0.01-0.025mm diameter), with tightly controlled diameter and typical tolerances of ±3%. It's used in sensors and to trigger airbags, essential to ensuring people's safety. So we work to the highest standards, ensuring a high level of process control and consistent quality.
And with its conductivity, high melting point, chemical inertness and extremely stable electrical properties, it's an exceptional Resistance Thermometer Detector (RTD). We can tailor make ingots for ultrafine alpha platinum wire to specific requirements through batch selection and careful doping. We supply wire with temperature coefficient of resistance (alpha value) of 0.003800-0.003925, with a tight tolerance up to ±3ppm. Commonly required wires for resistance thermometry include alpha values of:
- 0.003850 for the industry standard for most sensors outside the USA and Japan. Typical wire diameter is 0.018mm.
- 0.003900, originally specified for the British Aircraft Industry.
- 0.003916 for accepted standard in the USA and Japan.
- Greater than 0.003925 for high precision resistance thermometer detector using very pure platinum wire. Typical wire diameter is 0.07mm.
For gas sensing, we typically supply the following sizes:
- 0.025mm to measure 220ohm/m resistance (±3%)
- 0.015mm to measure 600ohm/m resistance (±5%)
- 0.0125mm to measure 865ohm/m resistance (±5%)
- 0.010mm to measure 1347ohm/m resistance (±5%)
Regalohm wire
As well as our pure and alloyed wire, we make Regalohm wire available to the following specific resistance in micro ohm cm:
- Regalohm 62 - 8% tungsten platinum
- Regalohm 42 - 40% silver palladium
- Regalohm 41 - 10% ruthenium platinum
- Regalohm 32 - 20% iridium platinum
- Regalohm 31 - 5% ruthenium, 15% rhodium platinum
- Regalohm 25 - 10% iridium platinum
- Regalohm 19 - 10% rhodium platinum
- Regalohm 11 - 20% palladium silver
- Regalohm 6 - 10% palladium silver
Zirconia grain stabilised (ZGS) wire
We offer ZGS platinum or 10% rhodium platinum wire. Dispersing zirconia particles into the metal considerably improves the performance by:
- Slowing down the degradation, extending the operating life
- Increasing its mechanical strength and durability
- Dramatically increasing resistance to grain growth, contamination and deformation.
