Testing different materials is Nanyang JZJ. Specifically, they perform an incredibly important piece of testing called the coefficient of thermal expansion test. So this test is extremely valuable because it tells us how materials perform when the temperature increases or decreases. It’s a little like making sure you know how a balloon expands when it blows up, and how it deflates when the air goes back out.
The coefficient of thermal expansion, a special term, explains how much any material expands or shrinks when the material is heated or cooled. Materials are made up of different things and react differently, so they have different coefficients of thermal expansion. For instance, metals might expand more than wood when heated. This information is very significant, especially regarding materials that will be in areas where there are extreme temperature fluctuations. There are several spaces where this is the case, such as airplanes, cars, and certain electronics (computers/phones).
The coefficient of thermal expansion test is performed by taking a small piece of the material and by heating it using a machine that is specially designed for it. This machine gently heats the material. As the material heats up, a special sensor measures how the material expands. It is like measuring how high a block of dough rises when you bake it. After the test is completed, the data obtained enables us to determine the coefficient of thermal expansion of that material.
Engineers and designers find it quite useful to know the coefficient of thermal expansion. That enables them to anticipate how a material will respond in various scenarios. In contrast, if in an environment with a high temperature difference, such as sunny days or cold high-temperature freezers, it is required to choose a low coefficient of thermal expansion material. This means that when it is heated or cooled, it will not change size as much. In contrast, materials with a very high coefficient of thermal expansion will undergo large expansion and contraction. This can cause issues such as bending and cracking or even breaking after a while.
The determination of coefficient of thermal expansion, therefore, is significant for checking the compatibility of dissimilar materials. In certain cases, not just one kind of material is used for the project. When different materials are used together, they can expand and contract at different rates. This difference can cause stress on the materials; this can result in cracks or breaking. For example, by testing the coefficient of thermal expansion for disparate materials, engineers can select the appropriate sets of materials that will not adversely affect one another. In other words, it prevents problems from happening over time while also ensuring the safety and strength of the materials.
We are very proud of our coefficient of thermal expansion testing products due to the fact that we are not just experienced application engineers but also design engineers who are focused on the details and operational. We have a wealth of knowledge in high-temperature testing, and are able to provide customized thermal testing equipment for specific projects. We also provide high-temperature technology consultation services and also test samples.
