Products Description
Tungsten wire gold plating refers to tungsten wire coated with a layer of gold. This tungsten wire is a special tungsten wire.The main function of gold plating is to prevent corrosion.
Gold plated tungsten wire,the surface condition is golden shiny tungsten wire,high temperature resistance,corrosion resistance,high melting point,low thermal expansion coefficient,which is suitable for using tungsten wire and tungsten heater.Tungsten wire gold plating increases corrosion resistance.
On the surface,tungsten wire gold plating becomes more beautiful,and the surface is brighter than black tungsten wire,white tungsten wire and spray coated tungsten wire.Therefore,the corrosion resistance of tungsten wire gold plating is much higher than that of ordinary tungsten wire.

Products Application
-
Tungsten wire gold plating is used as electrode wire for copiers instead of corrosive tungsten wire and tungsten-aluminum wire.It can also be used as an ideal corrosion resistant electron emission material, and can be widely used in scientific research fields such as high energy physics and meteorology.
-
Tungsten wire is a commonly used metal material.It has the characteristics of high melting point and corrosion resistance.Therefore,it is widely used in many fields.Tungsten wire gold plating can not only increase its aesthetics,but also improve its performance.In the field of biology,tungsten wire gold plating also has important applications.
1.Cell Imaging
Can be used as a carrier for cell imaging.Researchers can use gold plated tungsten wire to prepare probes,introduce its good electrical conductivity and optical properties,and observe the activities inside cells through a microscope.Compared with traditional cell imaging technology,this method has higher resolution and better stability,and can more accurately observe the structure and function of cells.
2.Drug delivery
Using it as a drug delivery carrier can improve the stability and delivery efficiency of drugs.Researchers can wrap drugs on gold-plated tungsten wires and control the release of drugs by regulating the surface properties and shape of the tungsten wires. This method can avoid premature decomposition and excretion of drugs in the body and improve the efficacy and bioavailability of drugs.
3. Cell culture
Tungsten wire gold plating has good biocompatibility and can be used as part of the cell culture matrix. Researchers can culture cells directly on its surface and regulate the shape and surface properties of the tungsten wire to promote cell attachment and growth. This method can better simulate the growth environment of cells in the body and provide more accurate data and information for cell research.
Gold plated tungsten wire process
The processes used for tungsten wire gold plating include pretreatment,cleaning, bottom plating,gold plating layer and post processing.
1.Pretreatment:The surface of the tungsten wire is polished,cleaned and degreased to ensure the adhesion and uniformity of the gold plating layer.
2.Cleaning:The pretreated tungsten wire is cleaned with acid or alkali cleaning to remove oxides and other impurities on the surface to ensure the purity of the surface.
3.Bottom plating:Plate a metal bottom layer on the surface of the tungsten wire,such as nickel,silver,copper,etc.,to increase the adhesion and gloss of the gold plating layer.
4.Gold plating layer:On the basis of the bottom plating layer,metal is plated on the surface of the tungsten wire using methods such as electroplating or chemical gold plating to form a metal plating layer.
5.Post processing:Clean,polish and package the metal-plated tungsten wire to ensure the quality and beauty of the finished product.
