Steel core aluminum stranded wire tensile testing machine

Product usage
This machine is an important instrument and equipment for testing the physical properties, mechanical properties, process properties, structural properties and internal and external defects of steel strands, rebars and their products. The tensile strength, yield strength, specified non-proportional extension strength, elastic modulus and other performance indicators of the measured material can be automatically obtained, and closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain can be completed.
