Achieved via further advancement of accumulated tungsten processing technology.
Processed tungsten wires finer utilizing the tungsten processing technology we accumulated through the production of lamp filaments and coils.
We developed extra-fine tungsten wires, metal wires that satisfy both straightness and surface smoothness as well as ultra-high strength tungsten wires.
Extra-fine tungsten wire
Extra-fine tungsten wire
[Application example: Mesh]
Fine wire with both the strength and surface smoothness suitable for secondary processing.
It contributes to the enhancement of product value mainly when used to produce mesh.
Reduced breaking of wire during mesh processing. Higher accuracy.
Excellent straightness and surface smoothness enable processing as though it is a fiber without breaking.
Extra-fine line
Smaller diameter and enhanced strength enable printing of finer lines. Contributes to the improvement of power generation efficiency.
Small distance
High elasticity specific to tungsten enables small distance.

Ultra-high strength tungsten wire
[Application example: Saw wire]
Exceeding the standard strength upper limit* for tungsten wires, maximum strength level for metallic wires is achieved.
Furthermore, it is suitable for bending or twisting.
*JIS H4461:2002_Tensile strength of wires
Reduces material loss and increases the number of obtained wafers.
Finer high-strength tungsten wire reduces loss during slicing.
Reduces the variation of wafer thickness and improves yields.
Highly elastic wire with less flexure enables high accuracy, even slicing.

Features of tungsten
Tungsten is a rare metal that has the highest melting point among metals and has advantages in heat resistance and use under high temperature.
Its elasticity is approximately twice as high as general ferrous metals. One of its features is smaller deformation than other metals under the same stress.
