Flat Wire Torsion Tester

-Determine the strenght of your wire by the number of twists it can withstand

A flat wire torsion test twists a flat wire along its length until a set number of twists or until it fails, in order to measure how well it withstands torsional loading and to reveal defects such as cracks or poor ductility.

​

What the test involves

• The wire is clamped at both ends, kept straight with a small axial load, and one end is rotated at a controlled speed while torque and angle of twist (number of turns) are recorded.​

• The test typically continues until the wire breaks or reaches a specified number of twists, giving results like maximum torque, twists to failure, and any visible enamel damage.​

Verifying ductility and torsional toughness

• It verifies ductility and torsional toughness of the flat wire, showing whether it can survive twisting during manufacturing, forming, winding, or installation without cracking.​

• It supports quality control and supplier qualification by detecting variability between batches, confirming compliance with standards (e.g., torsion limits), and reducing field failures related to wire breakage or enamel damage under twist.​
