The realization of this hardness is also inseparable from reasonable heat treatment process and exquisite manufacturing technology, which ensures that tungsten copper alloy can exert its excellent performance under various requirements.

Immediately after 40±2.0, tungsten copper alloy has another hardness range, namely 35±2.0. Similarly, the achievement of this hardness also depends on excellent heat treatment technology and superb manufacturing process, which together create the excellent performance of tungsten copper alloy in various applications.

After introducing the hardness ranges of 40±2.0 and 35±2.0, let’s take a look at another hardness option of tungsten copper alloy-30±2.0. The realization of this hardness is also inseparable from the exquisite heat treatment technology and excellent manufacturing process, which together ensure the excellent performance of tungsten copper alloy in various occasions.

After exploring the hardness range of 30±2.0, we turn to another hardness level of tungsten copper alloy-25±2.0. The achievement of this hardness also depends on exquisite heat treatment technology and excellent manufacturing process, which together create the excellent performance of tungsten copper alloy in various applications.

After understanding the hardness level of 25±2.0, we further explore the hardness diversity of tungsten copper alloy. The next hardness level to be introduced is 20±2.0, which also undergoes precise heat treatment and fine manufacturing process, thus ensuring the excellent performance of tungsten copper alloy under various needs.

After exploring the hardness grade of 20±2.0 in depth, we continue to explore the hardness diversity of tungsten copper alloys. Now, we focus on the new hardness grade of 15±2.0. Similarly, it has also undergone rigorous heat treatment and exquisite manufacturing processes to adapt to various application scenarios under different needs.

Discussion on thermal properties of tungsten copper composite materials

As the exploration of the hardness grade of tungsten copper alloy deepens, as a Chinese tungsten copper alloy supplier, we further pay attention to its thermal properties.
