1、 Tungsten alloy wire for photovoltaic silicon cutting
Tungsten alloy wire for photovoltaic silicon cutting has shown greater development potential than traditional carbon steel busbars due to its high strength,
good fatigue resistance, good conductivity, and great potential for fine wire. It is gradually increasing market penetration.

Tungsten wire diameter (μm) | Min tensile strength (N/mm ²) | Min breaking force (N) |
48≤d<50 | 5100 | 9.2 |
46≤d<48 | 5300 | 8.8 |
43≤d<46 | 5300 | 7.7 |
40≤d<43 | 5500 | 6.9 |
37≤d<40 | 5500 | 5.9 |
35≤d<37 | 5500 | 5.3 |
33≤d<35 | 5700 | 4.9 |
31≤d<33 | 5700 | 4.3 |
2、 Cutting resistant tungsten wire
Tungsten wire can be processed into extremely fine specifications, and compared to similar specifications of stainless steel, it has significantly improved strength
and hardness. It is used to manufacture cutting resistant protective gloves, which can make the gloves lighter, thinner, and softer while meeting the same level of
cutting resistance performance.
Tungsten wire gloves can effectively reduce skin irritation, make wearing more comfortable and flexible, and are suitable for various hand protection occasions.
Through excellent design, the cutting resistance level of gloves can be increased by more than 2 levels.
