The density of tungsten material is one of its most significant characteristics, about 19.3 g/cm³, which is much higher than most common metal materials (for example, the density of steel is 7.85 g/cm³). This high-density property is particularly important in metal processing tools. First of all, the high density of tungsten alloy rods gives them extremely high mechanical strength and stability, allowing them to withstand large mechanical pressure without deformation or breakage during high-load metal processing such as cutting, milling, and drilling. In high-intensity processing tasks, tungsten alloy rods can provide higher stability and durability, ensuring high precision and reliability during processing.
The high density of tungsten alloy rods enables it to effectively reduce vibration during high-speed cutting and maintain a relatively stable processing state. This performance plays an important role in improving metal processing accuracy, especially in precision processing, which can ensure the durability of processing tools and avoid processing errors caused by loosening or failure of tools. In addition, the high density of tungsten alloy rods also makes them more impact-resistant and wear-resistant, greatly extending the service life of tools. In mechanical processing, tungsten alloy rods are often used in the processing of hard materials such as cemented carbide and steel. Due to the high density of tungsten alloy rods, the friction and wear between the tool and the workpiece are small, which effectively reduces the wear rate of the tool and improves the processing efficiency.
High-density tungsten alloy rods can also withstand high-intensity impact loads and are suitable for occasions requiring high hardness and high wear resistance. For example, tungsten alloy rods can maintain their original shape and size during high-strength metal processing such as forging and die casting. Even if they are in a high-intensity friction or impact environment for a long time, tungsten alloy rods can avoid cracks or deformation, ensuring high precision and stability in the production process.
The melting point of tungsten is the highest among all metals, reaching 3422°C. Compared with other metal materials, the melting point of tungsten alloy rods provides great advantages, especially in applications where metal processing is required in a high-temperature environment, tungsten alloy rods can work stably for a long time without melting or failure. In the process of metal processing, high temperature is inevitable, especially when it involves cutting, milling, grinding and other processes of high-temperature alloys, hard metals and high-strength metals. Traditional metal materials are often prone to softening or melting under such high temperature conditions, resulting in rapid failure of cutting tools or reduced processing accuracy. The high melting point of tungsten alloy rods ensures that they can maintain stable hardness and strength in these high temperature environments, avoiding such softening and melting, thus ensuring efficient and high-precision processing.
The high melting point of Tungsten Carbide Rod/Tungsten Bar For Metal Processing makes them very suitable for the processing of high-temperature alloys and difficult-to-process materials, such as titanium alloys, aluminum alloys and other high-melting point materials. During the processing of these high-melting point and high-strength materials, tungsten alloy rods can effectively maintain their structural stability and avoid deformation and loss caused by high temperature. This feature makes tungsten alloy rods not only have advantages in ordinary metal processing, but also can meet the special processing needs of high-tech fields such as aerospace, automobile manufacturing, and electronic products.
In high-temperature processing, tungsten alloy rods can effectively avoid the adverse effects of thermal expansion. Due to the high melting point of tungsten alloys, their thermal expansion coefficient is small, which allows tungsten alloy rods to maintain a relatively stable size when working at high temperatures and are not easily affected by temperature fluctuations, thereby reducing the dimensional deviation caused by thermal expansion and further improving the processing accuracy. For high-precision processing tasks, this feature of tungsten alloy rods can undoubtedly bring significant advantages.
Application of high density and high melting point of tungsten alloy rods in metal processing
Metal cutting and drilling: The high density and high melting point of tungsten alloy rods make them particularly outstanding in cutting and drilling. In the process of metal processing, cutting and drilling often need to be carried out at high temperatures, especially in materials with higher hardness such as cemented carbide and steel. Traditional tools may soften or wear excessively at high temperatures, while tungsten alloy rods can withstand these extreme conditions due to their high melting point, ensuring the stability of the cutting process and effectively extending the service life of the tools.
Mold manufacturing: In the process of mold manufacturing, metal molds often need to withstand high temperatures and pressures, and the high density and high melting point of tungsten alloy rods make them ideal mold materials. Especially in casting, forging molds and die-casting molds, tungsten alloy rods can withstand strong impact and friction in high temperature working environments to avoid failure due to melting or softening.
High-precision machining: The high density of tungsten alloy rods can reduce machining errors caused by vibration and friction during machining, so in precision machining, tungsten alloy rods can ensure high-precision machining. For example, when manufacturing precision parts, mechanical parts, and aerospace-related components, tungsten alloy rods can maintain stable cutting forces to ensure that the size and shape of the workpiece meet strict requirements.
Heat treatment and welding: The high melting point of tungsten alloy rods enables heat treatment and welding operations at high temperatures, especially in metal processing that requires high-temperature heat treatment. Tungsten alloy rods can work stably without melting or deformation. Its high temperature resistance allows it to maintain strength and hardness in high temperature environments, and can be used in the manufacture of welding equipment and heating devices.
