Pt Ir Wire Description

Material processing

We select high-purity platinum and iridium materials and undergo vacuum induction melting, forging deformation processing, multi-pass drawing process, recrystallization annealing, surface pickling and polishing, straightening, aging treatment, and final quality inspection.

Characteristics

Good high temperature stability

High melting point, can maintain stable physical and chemical properties in high temperature environment, strong resistance to creep and deformation.

Long service life

Its corrosion resistance to hydrochloric acid, sulfuric acid and molten sodium hydroxide is better than that of titanium alloy and Hastelloy, and it has high surface hardness and good wear resistance.

Good thermoelectric performance

It has good electrical conductivity and is resistant to arc erosion. It also has high thermoelectric potential stability, which can provide accurate and reliable data support for temperature measurement.

Excellent biocompatibility

It can perform stable repair functions for a long time in the corrosive environment of body fluids, has a high degree of fit with human tissue, and will not break easily.

Application

Aerospace: Pt Ir Wire is used as a thermocouple wire for measuring high-temperature gas in the engine combustion chamber. It is resistant to oxidation and has better signal stability than pure platinum.
Medical and bioengineering: It is used as an electrode wire for implantable medical devices, such as pacemakers and cochlear implants, and can maintain low impedance and long-term stability in the complex electrolyte environment in the body. The high hardness and flexibility of platinum iridium wire can also be used to make microsurgical sutures for nerve or vascular anastomosis surgery.
Electronics and semiconductors: It can be used as a heating filament for evaporating metals such as tungsten and molybdenum in vacuum coating machines, and can also be used as a contact material for high-frequency communication relays.
Chemical industry: It is often used as a key component of chemical analysis instruments, catalytic reaction equipment, and gas analysis equipment. It can maintain structural stability in complex chemical reaction environments, promote reaction processes, and improve analysis efficiency and accuracy.
