Metal Wire Wrap Tester
Category：Material Strength Tester
Introduction
The Metal Wire Wrap Tester is designed to evaluate the ductility and winding performance of metallic wires. It measures the ability of wires to withstand plastic deformation under controlled tension and rotation, revealing surface defects such as cracks or inclusions that may not be visible otherwise. This instrument is widely used in metal wire production, quality control, research, and development to ensure consistent wire performance and compliance with national and international standards.
