TUNGSTEN WIRE, SAW WIRE, AND TUNGSTEN WIRE FOR SCREEN PRINTING

Document Type and Number:

Japanese Patent JP2022001660

Kind Code:

A

Abstract:

To provide, e.g., a tungsten wire having tensile strength higher than general tensile strength of piano wires.SOLUTION: A tungsten wire is made of tungsten or a tungsten alloy. The average width of surface crystal grains in a direction perpendicular to a wire axis of the tungsten wire is 98 nm or less. The tensile strength of the tungsten wire is 3900 MPa or more. The wire diameter of the tungsten wire is greater than 100 μm and less than or equal to 225 μm.SELECTED DRAWING: Figure 3
