1.Application:
The Metal Wire Torsion Testing Machine is suitable for measuring the ability of metal wire with a diameter (or characteristic size) of 1.0- 10.0mm to withstand plastic deformation in one-way or two-way torsion and to display the surface and internal defects of the wire.
This machine is mainly used for the analysis of the mechanical properties of metal wires in the mechanics laboratories of colleges, universities, scientific research departments, and industrial and mining enterprises. It is also widely used for online inspection of production units; the main industries include high-speed steel lines,prestressed steel wire plants, and quality Supervision, scientific research institutes, highway transportation,construction industry, steel wire ropes, wires and cables, copper and copper alloy wires for electrified railways, copper contact wires and other production and use departments.
