Wire Torsion Tester

Applicable standards:

GB/T 239.1-2012 "Metal materials wire Part I unidirectional torsion test method"

GB/T 239.2-2012 "Metal materials wire Part II Bidirectional torsion test method"

ISO 7800:2003 "Test method for unidirectional torsion of metal wires"

ISO 9649:1990 Test method for bidirectional torsion of metal wires

Product Advantages:

Evaluates Torsional Ductility: Directly measures the wire's ability to withstand twisting before fracture.

Standardized Testing: Enables testing according to widely recognized national and international standards.

Reveals Defects: Torsional stress can highlight material imperfections or inconsistencies not apparent under other tests.

Supports Quality Control: Provides a reliable method for ensuring consistent wire quality.

Versatile: Can perform both unidirectional and bidirectional torsion tests.

Controlled Parameters: Allows for precise control of twisting speed and specimen length for repeatable results.

Test principle:

Unidirectional torsion: The sample rotates 360 degrees evenly around its axis in one direction as a single torsion to the specified number of times or the sample breaks.

Two-way torsion: the sample rotates 360 degrees evenly around its axis in one direction as a torsion to the specified number of times, and then rotates the same number of times in the opposite direction or the sample breaks.
