How Can Ductility Of Metals Be Tested?

Metals have a wide presence in our world. They are widely used in domestic fronts and industries to fulfil the requirement of different applications. The wide requirement of metals in different fields includes automobiles, constructions, electrical products, industrial machine and many more. The different applications where metals are used on a large scale require high-quality metals to ensure the performance & efficiency of the final product. In such areas, there is no space for quality defects, and flaws as these defects can harm the safety of the users and can also lead to horrible consequences. This makes the manufacturers of metal goods, extra conscious about the better quality of the products.

How can the quality of metals be ensured?

The manufacturers can test the quality of the products that they manufacture in their premises using high-quality testing machines and standardized test procedures. Using these testing machines, the manufacturers can clearly evaluate the properties of the metals such as chemical composition, physical strength and can also predict the behavior of the material in specific conditions.

Quality Testing of Metals with Testing Devices

These testing devices help the manufacturers to decide the factor of safety for the usage of the products and offer the best quality to the clients. For better quality assurance of the products, the manufacturers need to commence high-quality testing machine at different points such as raw material inspection, design process, manufacturing procedure, until the final good is produced. Ignoring the quality at any of the points can lead to degradation of the quality of the products that can lead to huge losses. The major testing procedure which is conducted on the metals is Cupping Test. This test is conducted to determine the ductility of the metals.

How to perform Cupping test for metal quality determination?

  • The test specimen is placed under a shearing force that can be applied on the material with the help of a round
  • This indenter helps to exert a specific amount of shearing force on the specific portion of the sample that causes the formation of a small cup on the one side of the test sample.
  • The load sensor presents the records of the indenter shearing force which is applied to the metal plate.

In this manner, the maximum value of force is determined which can be applied on the metal plate without cracking it. Many times, the test is also used to test the elasticity of the paints that are used on the metal surfaces.

The cup shape formed at the time of test is analysed for any cracks that have been developed on the surface of the paints that are applied to the metals. Therefore, it can be used to test the quality of the metals and coatings of the paints on metal surfaces. For more information, click here.
