Description
Casting Tungsten Carbide Powder is manufactured by melting Tungsten metal and Carbon together. It has two eutectic compositions: WC and W2C. The melt is cast through quenching into extremely hard solid particles of fine crystal structure.
Application
Our Casting Tungsten Carbide is characterized by good wear resistance and weldability. It is widely used in spray welding, immersion, and spray coatings.

Precautions
（1）Health Hazards
Tungsten dust can lead to peribronchial inflammation, peribronchiolitis, bronchiolitis obliterans, and atrophic emphysema. Tungsten carbide exposure may cause a proliferative response in lung lymphatic tissues, eventually leading to sclerosis. It can also result in vascular wall thickening and uniformity. Workers exposed to tungsten carbide dust may experience gastrointestinal disturbances, kidney irritation, and catarrhal inflammation in the upper respiratory tract. The maximum permissible concentration of tungsten carbide is 6 mg/m³. In the United States, the maximum permissible concentration for soluble tungsten compounds (as tungsten) is 1 mg/m³, and for insoluble tungsten compounds (as tungsten), it is 5 mg/m³.
（2）Safety Precautions
Use approved respirators, dust-proof clothing, gloves, and protective eyewear. Prevent dust leakage at all stages of production. Workers should undergo a pre-employment health examination and have annual check-ups. If significant respiratory symptoms appear, the worker should be temporarily reassigned away from tungsten exposure. In cases of lung sclerosis or impaired external respiratory function, reassignment away from exposure is required.
Packaging of SAM Casting WC Powder
Our casting tungsten carbide powder is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
