Platinum wire (Pt wire) is silvery white, has a metallic luster, and is soft. Due to its good ductility, thermal conductivity, and electrical conductivity, it is widely used in aerospace, medical, military, and electrical applications. These applications include resistance thermometers and combustible gas detectors. Because platinum is stable, it is used in medical implants. Platinum wire is also used in aircraft engines, heat exchangers, turbines, and infrared detectors. Platinum wire also shows good performance in semiconductor manufacturing. Wire specifications can also be customized according to customer requirements, including specific specifications such as resistance and temperature coefficient, true resistance, and tensile requirements.

Platinum Rods

Platinum Wire Specification:

Material:Platinum (Pt)(≥ 99.99% or ≥99.95%)

Size: Wire diameter 0.02 mm~10.0 mm, or customized(Hard and soft conditions can be processed according to customer requirements. Generally, 0.2mm and above default to soft state, and 0.2mm and below default to hard state.)

The conventional resistance ratio of platinum wire 0.02mm and 0.03mm is above 1.3850. If you need a platinum wire with other resistance ratios, it needs to be customized, such as 1.3920 or above.
