Tungsten Carbide Bushings
Tungsten Carbide Bushing is a precision manufactured bearing assembly made from high purity tungsten carbide material, which is widely used in a variety of mechanical equipment due to its unique physical properties. The extremely high hardness of this material, which often exceeds that of other metallic materials, enables tungsten carbide bushings to exhibit excellent wear resistance in the face of extreme friction and wear.

Tungsten Carbide Centrifuge Tiles
Tungsten carbide centrifuge tiles are components made from tungsten carbide, a material renowned for its exceptional hardness and wear resistance. These tiles are designed to withstand the harsh conditions often encountered in industrial centrifuge applications, where repeated high-speed rotational forces can cause significant wear and tear on equipment components.

PDC Drill Bit Nozzle
The role of tungsten carbide nozzles in PDC drills is crucial, and tungsten carbide nozzles are a part of PDC drill bit. The main function of the nozzle is to realize efficient cooling and cleaning of rock chips during drilling. During the drilling process, the nozzle is responsible for spraying flushing fluid at high pressure into the drilling area, removing chips and cooling the bit to prevent overheating. At the same time, the design of the nozzle allows the fluid to be effectively dispersed in the drilling hole, reducing frictional resistance and improving drilling efficiency.

Tungsten Carbide Plate
Langsun Carbide uses high quality tungsten carbide powders to manufacture tungsten carbide plates. These powders consist of tungsten powder and carbon powder mixed in a certain proportion to form a homogeneous mixture, adding cobalt powder or other binder for sintering at high temperatures. During the sintering process, the powder particles combine with each other to form a dense tungsten carbide solid. Finally, tungsten carbide plates of the required size and surface finish are obtained through mechanical processing, such as cutting and grinding, or tungsten carbide plate blanks can be provided. Throughout the process Langsun Carbide strictly controls the temperature and atmosphere to ensure the performance and quality of the product.

Tungsten Carbide Rods
Tungsten carbide rods are mainly used in industrial cutting tools and abrasives for making high quality tungsten carbide tools. Tungsten carbide rods are able to withstand severe mechanical wear and extreme temperature variations when operating at high temperatures or pressures. In its structure, tungsten and carbon combine to form a strong crystal lattice, which makes the material not only hard but also has good thermal conductivity.

Tungsten Carbide Seal Rings
Tungsten carbide sealing rings are high-performance sealing components that are widely used in mechanical sealing systems such as pumps and compressors. As a material composed of the elements carbon and tungsten, tungsten carbide has excellent wear and corrosion resistance, making it an ideal sealing material. Seal rings are usually divided into dynamic and static rings, where the dynamic ring is connected to the rotating device and rotates with it, while the static ring is fixed in the housing of the sealing device, and both of them work together to realize an effective seal.
