A test probe is a tool used to test electronic components, (coaxial current probe supplier china) which can detect electrical signals on a circuit board to determine whether the circuit board is working properly. The material of the test probe is very important because it directly affects the accuracy and reliability of the test. So, what metal is the material of the test probe?

The material of the test probe is usually tungsten, molybdenum, copper, silver,（high current pogo pin connector supplier china） and other metals. Among them, tungsten and molybdenum are the most commonly used materials because they have high hardness, high melting point, and good conductivity. The hardness of tungsten and molybdenum is very high, which can maintain the shape and size of the probe unchanged during the testing process, thereby ensuring the accuracy of the test. In addition, the melting points of tungsten and molybdenum are also very high, which can be used in high-temperature environments without deformation or damage due to excessive temperature. Copper and silver are also commonly used test probe materials, which have good conductivity and can ensure the transmission quality of test signals.

In addition to material selection, the manufacturing process of the test probe is also very important. (guide pin manufacturer china) The manufacturing of test probes requires precise machining and surface treatment to ensure accurate size and shape of the probes, as well as smooth surfaces that do not interfere with the test signal. In addition, the tip of the test probe also requires special treatment to ensure its good penetration and contact performance.

In short, the material of the test probe is very important, as it directly affects the accuracy and reliability of the test. Tungsten, molybdenum, copper, silver, and other metals are commonly used test probe materials, which have different characteristics and advantages and can be selected according to specific testing needs. In addition, the manufacturing process of the test probe is also very important, requiring precision machining and surface treatment to ensure that the size and shape of the probe are accurate, and the surface is smooth, without interference with the test signal.·
