ZZKD is a major supplier of Metalizing Filaments to the vacuum metalizing and evaporation industries. They are engineered to provide reliable thin film coatings on automotive lamp reflectors, and various decorative applications in appliances, specialized machinery, cosmetics and more.
We offer coils in a wide variety of designs: single strand; three strand; with or without aluminum core; and open or closed lay. In addition to the popular "Z" leg coil, we provide many other styles, including helix configurations and conical and cylindrical basket designs.
The standard wire size is 3/030 - but many other sizes are readily available.
Our high quality Tungsten Filaments provide excellent uniform thermal conductivity, ensuring reliable performance and long life. We also offer expert on-site technical service.
Item: Pure tungsten filament.Purity: 99.95%Min.
Type: HW91/HW71/HW61/HW31/HW11 etc.
Size: According to customer's drawing and true sample.
Tungsten wires are made of selected high-quality material of tungsten, with the properties of excellent thermal conductivity, finely processed, and long duration.
Unusual stranded tungsten wires are applied as evaporator (heating element) in the vacuum metallizing (evaporation) process to coat thin film on surface of mirrors, kinescope, toys, home appliance, machine and various decoration, etc.
