Tungsten is a rare high melting point refractory metal with irreplaceable industrial value. Owning the highest melting point among all metals, it is the core raw material for manufacturing high-temperature furnace components, heating elements and thermal shielding parts, widely used in high-temperature industrial kilns and vacuum sintering equipment. In electronic and electrical industry, it is made into tungsten wire for incandescent lamps, halogen lamps and electron tube electrodes, also applied in semiconductor wafer processing and precision electronic welding materials. In new energy field, tungsten powder and tungsten alloy are used for lithium battery high-density structural parts, new energy vehicle motor heat dissipation components and power battery high-temperature resistant accessories, effectively improving equipment stability under extreme temperature. It is also essential for producing hard alloy cutting tools, mining drill bits and wear-resistant mechanical parts, greatly enhancing product hardness and service life. In aerospace and military industry, it is used to make high-strength heat-resistant structural parts and counterweight materials. Besides, it is widely used in radiation shielding, medical equipment accessories and chemical corrosion-resistant equipment. With outstanding physical and chemical properties, tungsten covers high-temperature industry, new energy, electronic manufacturing, aerospace and many core fields, maintaining steady global market demand.

Pure tungsten metal itself has low toxicity and high safety in conventional use. Direct contact with bulk tungsten materials will not cause skin irritation or allergic reactions. Long-term inhalation of fine tungsten powder will stimulate respiratory tract, easily cause dry throat, cough and chest discomfort, and long-term excessive inhalation may affect lung health. Eye contact with metal powder will produce foreign body sensation and mild conjunctival irritation. Accidental intake of a small amount will not cause obvious poisoning symptoms, while large intake may cause slight gastrointestinal discomfort. During powder operation, operators must wear dust-proof masks, protective gloves and dust-proof work clothes, and keep working area well ventilated to reduce dust diffusion. Store products in dry and ventilated place, sealed to prevent surface oxidation, keep away from strong oxidants, flammable materials and corrosive chemicals, and separate from food and daily necessities. In case of skin adhesion, clean with flowing water timely; if powder enters eyes, rinse with plenty of clean water continuously. Waste tungsten scraps can be recycled and reused, and abandoned powder shall be disposed in accordance with industrial solid waste standards, avoiding random stacking to prevent dust pollution, so as to guarantee personal operation safety and surrounding environmental safety.
