Gold Plated Molybdenum Wire A Versatile Product for Electronics
High-Temp Vacuum and Aerospace applications
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!
