Tungsten Wire
Tungsten wire is universally used to make tungsten wire resistance for bulbs, lamps. It can also be used to make optical instruments, electric vacuum components, and high-temperature resistant parts. Tungsten wire is characterized by the highest melting point and excellent electric conductivity. It has a high-performance in sintering and high-temperature in recrystallization. For the above features, it can serve a long life in many applications.
Type: Pure tungsten wire, WRe wire, gold-plated tungsten wire Diameter: 0.01 – 1 mm
Tungsten Alloy Wire For Photovoltaic Crystalline Silicon Cutting
Tungsten alloy wire for photovoltaic crystalline silicon cutting has greater development potential than traditional carbon steel busbars due to its high strength, good fatigue resistance, good conductivity, and high potential for thinning wires, and is gradually increasing market penetration.

Cut-resistant Tungsten Wire
Tungsten wire can be processed into extremely fine specifications. Compared with stainless steel of similar specifications, the strength and hardness are greatly improved. It is used to make cut-resistant protective gloves, which can make the gloves lighter, thinner and softer while meeting the same level of cut-resistant performance.
Tungsten gloves can effectively reduce skin irritation, make them more comfortable and flexible to wear, and are suitable for a variety of hand protection occasions. Through excellent design, it is expected to increase the cut resistance level of gloves by more than 2 levels.
