Automatic thread rolling machines are a type of automated equipment widely used in the field of metal processing, with their application scope covering a variety of materials. Specifically, automatic thread rolling machines are suitable for the following materials: 
Metal materials: 
• Steel: including high-speed steel, carbon steel, alloy steel, etc. Due to their high strength, high hardness, or good toughness, these steels are often used to manufacture fasteners that need to withstand high stress or high wear, such as bolts, nuts, etc. Automatic thread rolling machines can efficiently and accurately process the required threads on these steels. 
• Stainless steel: Due to its corrosion resistance and aesthetic appearance, stainless steel is widely used in many industries. Automatic thread rolling machines can also handle stainless steel materials to produce fasteners that meet the requirements. 
• Non-ferrous metals: such as copper, aluminum, zinc, etc. Although these materials may have lower hardness and strength than steel, they have unique advantages in certain specific applications, such as electrical conductivity, thermal conductivity, or light weight. Automatic thread rolling machines can also process these non-ferrous metal materials to meet the production needs of related products. 

Wire rods: 
• Automatic thread rolling machines are also suitable for processing various wire rods, such as steel wires, stainless steel wires, non-ferrous metal wires, etc. When these wire rods are processed into fasteners or other threaded parts, they need to go through processes such as cutting and thread rolling, and automatic thread rolling machines can efficiently complete these tasks. 

It should be noted that although automatic thread rolling machines are applicable to a variety of materials, in practical applications, it is still necessary to select appropriate processing parameters and tools according to the physical and chemical properties of the materials and the processing requirements of the products to ensure processing quality and production efficiency. 
In addition, with the continuous development of materials science and the continuous emergence of new materials, the application scope of automatic thread rolling machines is also expanding. For example, some new alloy materials or composite materials may have unique properties and application fields, and these materials can also be processed by automatic thread rolling machines.
