Platinum iridium wire: shaping the invisible "lifeline" of precision medicine

In the materials science map of Shanghai Wewei Technology, PtIr wire, as a key basic material, is like an indispensable "invisible lifeline" in precision medical equipment. It provides a crucial material foundation for modern diagnostic and therapeutic devices with excellent physical and chemical properties, unparalleled biological safety, and stable processing performance, especially playing an irreplaceable core role in cutting-edge fields such as neural stimulation, cardiac electrophysiology, and minimally invasive sensing.

The Peak Choice of Materials Science: Why Platinum Iridium Alloy?
Platinum iridium wire is not a simple metal wire, but a special alloy wire made by melting platinum (Pt) and iridium (Ir) in precise proportions. This combination can be called the "golden partner" of materials science:

Excellent stability of platinum: Platinum has excellent chemical inertness, biocompatibility, and conductivity, ensuring its long-term stability in complex human environments without the release of harmful ions.

The strength enhancement of iridium: The addition of iridium significantly improves the mechanical strength, hardness, and wear resistance of the alloy, allowing the wire material to maintain structural integrity and functional reliability even under repeated bending and small dimensions.

This combination enables Wewei's platinum iridium wire to possess ideal biocompatibility, excellent electrical signal transmission efficiency, and mechanical durability sufficient for precision machining and long-term implantation.

The core of precision manufacturing process: reliable guarantee from micrometer to nanometer level
Shanghai Wewei Technology relies on advanced metallurgical purification, precision drawing, and heat treatment processes to push the quality of platinum iridium wire to the extreme. By strictly controlling the alloy composition, grain structure, and surface finish, we are able to provide highly consistent wire materials with different diameter specifications ranging from tens of micrometers to several millimeters.

High purity and consistency: Ensure that the electrical and mechanical properties of each batch of materials are highly stable, laying the foundation for the mass production and quality control of downstream medical devices.

Excellent surface quality: extremely low surface defects and specific roughness control are beneficial for subsequent coating adhesion, welding processing, and reduce the risk of fibrosis in the body.

Flexible customization capability: We can provide customized alloy ratios and wire diameter solutions based on customers' special requirements for resistivity, tensile strength, flexibility, etc.

Empowering cutting-edge medical applications: a solid bridge from concept to clinical practice
The application of Wewei platinum iridium wire is deeply embedded in the core scenarios of modern healthcare:

Neural regulation and stimulation: As the core wire of deep brain electrical stimulation electrodes, spinal cord stimulators, vagus nerve stimulators and other devices, it is responsible for accurately transmitting therapeutic electrical pulses.

Cardiac rhythm management: used to manufacture electrode leads for pacemakers and defibrillators, requiring extremely high fatigue resistance and long-term conductivity stability.

High precision sensing: As a reliable signal transmission medium in physiological parameter sensing probes and functional components of endoscopes.

Minimally invasive surgical instruments: As functional components of precision surgical tools such as electric knives and ablation probes, they require high strength and corrosion resistance.
