Application of gold-plated tungsten wire in medical springs
1. High-Strength and High-Elasticity Support
Gold-plated tungsten wire offers high strength and excellent
elastic modulus, making it suitable for manufacturing micro-springs
in precision medical devices, ensuring stability and reliability
during complex operations.
2. Corrosion Resistance and Biocompatibility
Gold plating provides excellent corrosion resistance, reduces metal
ion leaching, and improves the material's biocompatibility in the
human body, making it suitable for medical devices intended for
long-term implantation or contact with human tissue.
Conductive Properties
Gold-plated tungsten wire springs not only have mechanical
properties but also serve as conductors in medical devices such as
minimally invasive surgical instruments and electrophysiology
equipment, playing a vital role in signal transmission.
3. Gold Plated Tungsten wire of applicability for Precision Medical
Devices
They are widely used in cardiovascular stent delivery devices,
interventional surgical instruments, guidewire advancement systems,
minimally invasive surgical tools, and spring components for
implantable devices, meeting the medical industry's stringent
requirements for precision, reliability, and durability.
What is Gold-Plated Tungsten Wire?
Gold-plated tungsten wire is made by coating a tungsten core with a
layer of gold through electroplating or other advanced techniques.
This combination leverages tungsten’s exceptional mechanical
properties—such as high melting point and tensile strength—while
enhancing its surface with gold’s excellent conductivity, corrosion
resistance, and biocompatibility.
Key Features of Gold-Plated Tungsten Wire
1 . High Strength and Durability
Tungsten’s high tensile strength and resistance to wear make it
ideal for applications requiring robust materials.
2 . Excellent Conductivity
The gold coating provides superior electrical conductivity, making
the wire suitable for high-precision electronic connections.
3 . Corrosion and Oxidation Resistance
Gold’s resistance to tarnish and chemical reactions ensures the
wire remains reliable in harsh environments.
4 . Biocompatibility
Gold is biocompatible, making gold-plated tungsten wire a preferred
material for medical and biological applications.
5 . Thermal Stability
With tungsten’s high melting point (3,422°C), the wire can
withstand extreme temperatures, ideal for aerospace and
high-temperature environments.
We can customize the diameter of white tungsten wire, polished
tungsten wire, and black tungsten wire, as well as the thickness of
the gold plating on gold-plated tungsten wire. We offer custom
diameters from 0.01 to 0.05mm, and custom thicknesses from 0.01 to
2µm. We can also provide professional advice based on your
drawings, tensile strength, performance, and other requirements.
The diameter, length and spool of pure tungsten wire and
gold-plated tungsten wire can be customized according to your
reqyirements.
