Tungsten wire and tungsten product

A tungsten wire is a tungsten wire containing tungsten or a tungsten alloy, a diameter of the tungsten wire is at most 100 μm, and a total number of torsional rotations to breakage per length of 50 mm of the tungsten wire is greater than or equal to 250×exp(−0.026×D) when a tension that is 50% of a...

Zusammenfassung:	A tungsten wire is a tungsten wire containing tungsten or a tungsten alloy, a diameter of the tungsten wire is at most 100 μm, and a total number of torsional rotations to breakage per length of 50 mm of the tungsten wire is greater than or equal to 250×exp(−0.026×D) when a tension that is 50% of a breakage tension of the tungsten wire is applied as a load, D denoting the diameter of the tungsten wire.
