What are some common materials that are tested with the tensile testing machine?

Tensile testing machines are widely used to test the tensile properties and mechanical properties of various materials. The following are some common materials tested with tensile testing machines:

1. Metal materials: including steel, aluminum alloy, copper alloy, nickel alloy, etc. These materials are widely used in engineering to manufacture structures and components, and tensile tests can evaluate their strength, ductility, fracture behavior, etc.

2. Plastics: such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), etc. Tensile testing can be used to determine the strength, modulus of elasticity, elongation and fracture properties of plastics to assess their reliability and performance in applications.

3. Rubber and elastomers: such as natural rubber, nitrile rubber (NBR), styrene-butadiene rubber (BR), silicone rubber, etc. Tensile testing can measure the tensile strength, elongation at break, stress-strain curve, etc. of rubber to evaluate its durability and reliability.

4. Fibers and textiles: including cotton, polyester, nylon, silk and other fiber materials, as well as textiles such as fabrics and cloth. Tensile tests can determine the strength, elongation, modulus of elasticity, etc. of fibers and textiles, which is of great significance to the quality control and performance evaluation of textile materials.

5. Polymer materials: such as polymers, composite materials and composite fibers. Tensile testing can test the mechanical properties of these materials, including strength, stiffness, fracture toughness, and failure behavior, to assess their viability for structural and engineering applications.

6. Wood and paper: Tensile testing of wood and paper using a tensile testing machine can determine its mechanical properties such as strength, ductility, and anisotropy.

These are just a few examples of the common range of materials tested with tensile testing machines, there are many other materials whose mechanical properties can also be evaluated by tensile testing.
