Lightweight and Ductile The Advantages of Gold Plated Molybdenum
Wire in Electronics and Aerospace Industries
Discover the groundbreaking gold plated molybdenum wire that revolutionizes precision engineering in electronics and aerospace industries. Our advanced composite wire combines molybdenum's exceptional
strength (tensile strength 1800-2200 MPa) with gold's superior
conductivity (resistivity 2.4 μΩ·cm), delivering unmatched
performance in extreme environments.
Key Advantages:
* Weight reduction: 40% lighter than traditional tungsten solutions (density 10.2
g/cm³ vs 19.25 g/cm³)
* Enhanced ductility: Achieves bending radius ≤0.5mm without fracture (ASTM E290
standards)
* Corrosion resistance: Withstands 1000+ hours in salt spray tests (ASTM B117)
* Thermal stability: Maintains structural integrity from -200°C to 1200°C
Industry-Specific Benefits:
Electronics Applications:✓ Semiconductor lead frames (JEDEC MS-034 compliant)
✓ High-frequency RF connectors (impedance stability ±1%)
✓ MEMS device interconnects (25-100μm diameter options)
Aerospace Solutions:✓ Satellite wiring harnesses (MIL-DTL-83513 certified)
✓ Rocket engine sensors (thermal cycling tested)
✓ UAV structural components (CTE 4.8×10⁻⁶/K)
The gold plating thickness (0.1-5μm customizable) ensures optimal solderability while our
proprietary alloy formulation (Mo+Re 0.5-2%) prevents intergranular
cracking. Compared to pure gold wires, our solution offers 30% cost
reduction with 15% higher conductivity - verified by ISO 17025
accredited labs.
Engineered for high-reliability applications where weight savings and signal integrity are critical. Request

Gold Plated Molybdenum Wire offers a few advantages versus gold
plated tungsten wire. Gold plated molybdenum wire is lighter than
tungsten and more ductile. The ductility of molybdenum wire allows
it to be woven and used in specific applications like antennae on
satellites. Like tungsten wire, gold plated molybdenum wire is used
in the medical and electronics industries.
Application area
Gold-plated molybdenum wire is applied in:
* Electronics: In semiconductors for wire bonding and in
connectors. Molybdenum gives strength, gold plating offers
conductivity and corrosion resistance.
* High-Temp & Vacuum: As heating element in vacuum furnaces and
sensing element in high-temp sensors. Gold plating reduces
evaporation and ensures accuracy.
* Aerospace & Defense: For spacecraft and missile systems, ensuring
reliable operation under extreme conditions.

The characteristics of gold plated molybdenum wire makes it
suitable for different electronic applications.
Besides reasons like protection against corrosion another cause for
gold plating is to achieve good electrical contact
and also an improved wettability for soldering.
Gold plated molybdenum wire is a good alternative where you would
like your plated wire, at a given wire dimension,
to be less heavy than for tungsten. Another product feature that is
different to tungsten is the better ductility for
gold plated molybdenum wire.
Standard gold coat thickness is 3-5% by weight. For a dimension
range of 0.015 – 0.150mm this corresponds to a gold
coat thickness of 0.1 – 0.8 micron. Upon request we also
manufacture gold plated molybdenum wire with non-standard
coat thicknesses, like for example 1 or 2 micron.
Our plating technology is constantly improved and this work is
facilitated by the fact that we are also designing our own
plating equipment. This allows us to meet our customers demand for
a well adhesive and dense gold coat
with uniform thickness.
Our modern scanning electron microscope is an example of an
instrument that allows us to confirm the continuous
improvements of our manufacturing technologies.

1.What kind of Enameled copper wire do Winner produce?
We focus on research and development of selfbonding magnet round
copper wire, fine polyurethane magnet wire, selfbonding litz copper
wire and selfbonding silk covered wire.
2.What's diameters available of the Enamelled copper wire ?
We specialize in fine and ultra fine enamelled copper
wire,diameters available of our products is Φ0.018-0.50mm.
3.What's selfbonding enameled copper wire?
Selfbonding enamelled copper wire is a special type of enamelled
wire with an additional adhesive enamel overcoat such as
thermoplastic resin.This adhesive has a bonding feature, which is
activated
by heat or solvents.
Once activated the adhesive bonds turn to turn windings into a
compact self supporting coil.
The use of selfbonding wire may offer cost and manufacturing
advantages in some winding applications
as bobbins, tape, varnishing, or impregnation may be eliminated.
4. Is possible to get any sample of selfbonding enamelled copper
wire that you have in production?
Of course you can!
