According to the structure, tungsten steel bar can be divided into tungsten steel bar for PCB tool, solid tungsten steel bar, single straight hole tungsten steel bar, double straight hole tungsten steel bar, double spiral hole tungsten steel bar, triple spiral hole tungsten steel rods and other types of tungsten steel rods, etc.

Tungsten steel, also known as cemented carbide, refers to a sintered composite material containing at least one metal carbide. Tungsten carbide, titanium carbide, and tantalum carbide are common components of tungsten steel.

Steel is widely used in industrial production due to its high strength, corrosion resistance, high temperature resistance, impact resistance, good plasticity and easy processing.

Molybdenum steel is a high-strength alloy used in a variety of industries. Steel alloys made with molybdenum are not only stronger and harder, but they are also highly resistant to heat and corrosion. Electronics, heavy machinery parts, tools and aircraft parts are often manufactured from molybdenum-containing steel alloys.
