Machine Model: LT-802 Wire tensile testing machine   I. Overview of Wire Tensile Testing Machine
The wire tensile testing machine is a commonly used device for testing the tensile strength of metal wires, steel wires, copper wires, steel stranded wires, or similar materials; its specialized clamps are designed according to the characteristics of the wire material, avoiding slippage and damage to the test specimen during the tensile test; it serves as one of the quality control methods for wire and cable, steel rope, and non-ferrous metal processing enterprises.   Section 2: Technical Specifications of Wire Tensile Testing Machine

Basic Knowledge of Wire Tensile Testing Machine:
When clamping wire materials, due to the small specimen size, it often results in the specimen being in varying degrees of bend. If an automatic extensometer is clamped at this point to begin testing, it may affect the extensometer's assessment of the specimen elongation. Therefore, it is necessary to pre-load the wire material, with the preload strength generally not exceeding 5% of the specimen's yield strength.
