  Copper alloys, like brass or bronze, are often used in terminal blocks' manufacturing because they have great mechanical properties and corrosion resistance. These materials are useful in environments that experience high humidity, temperature variations, or exposure to chemicals because they add to the terminal block's long-lasting nature. Since they are also good conductors of electricity, copper alloys are used in terminal blocks to enhance their overall conductivity.

• Plastic

  In manufacturing terminal blocks, plastics like polyamide and polyethylene have insulating properties. These terminal blocks come with great protection against short circuits, which may occur due to unintentional contact between conductive parts. The lightweight nature of plastic contributes towards easier installation, while its durability provides resistance against mechanical impacts and, at times, even against moderate heat. When it comes to safety, since insulated blocks are particularly for preventing electrical hazards, plastic is the most ideal material.

• Steel

  Steel can be found in terminal blocks because of its application in heavy-duty or industrial settings. For example, terminal blocks are mounted onto DIN rails in industrial control systems. In those applications, reliability and stability are essential. In this case, steel blocks will provide the required support and will last against wear and tear encountered throughout an operation. Also, galvanised steel, which offers extra corrosion protection, is often used in terminal blocks by outdoor applications.

• Elastomer

  Elastomer components can be found in terminal block designs and help to reduce vibration dampeners. Elastic materials are inserted into the construction of terminal blocks to absorb shocks caused by operating machinery nearby. Therefore, the terminal block will be well protected from any possible damage caused by constant motion over time. This will also help to expand the lifespan of the electrical connections.
