What customer we serve?
Ultrafine tungsten wire is widely used in medical, electronics, industrial, aerospace, and new energy sectors thanks to its high tensile strength, biocompatibility, conductivity, and resistance to high temperature and corrosion.
Medical
Our ultrafine tungsten wire is widely used in medical, electronics, industrial, aerospace, and new energy sectors thanks to its high tensile strength, biocompatibility, conductivity, and resistance to high temperature and corrosion.
Electronics and Industrial Usage
In electronics, tungsten wire is a key material for integrated circuits, vacuum deposition coils, electron-beam emitting devices, and EDM (electrical discharge machining) electrodes for precision cutting and shaping
Photovoltaics and Renewable Energy
In the photovoltaic industry, our ultra-fine, high-strength tungsten wires for slicing silicon wafers through “diamond wire” technology, improves efficiency and reduces material loss.
Aerospace and Advanced Engineering
Aerospace applications account for a significant share of ultrafine tungsten wire usage, especially in high-performance electronic components, sensors, and specialty cables exposed to extreme conditions.
Materials Science and Research
Ultrafine tungsten wire is an essential material in experimental physics (such as inertial confinement fusion), scientific imaging (SEM, borescopes), and advanced ionizers and terahertz polarizers
Safety Gloves & Protective Textiles
As industrial safety standards evolve, the demand for high-performance PPE has surged. Our cutting resistance tungsten wire for safety gloves is engineered to replace traditional bulky steel wires and irritating glass fibers. By blending our ultra-fine tungsten wire with HPPE or UHMWPE, manufacturers are creating next-generation cut-resistant gloves that deliver extreme heavy-duty defense without compromising on tactile sensitivity.
🛡️ Extreme Cut Defense (ANSI A9 / EN388 Level F)
Tungsten’s inherent high density and exceptional tensile strength provide maximum resistance against sharp metal edges, glass, and blades, easily helping your finished gloves achieve top-tier cut resistance certifications.
🧤 Zero Skin Irritation & High Dexterity
Unlike traditional fiberglass that causes skin itching, our glass-free tungsten wire ensures a skin-friendly fit. Reduce glove thickness by up to 50% while maintaining protection, enabling highly dexterous, touchscreen-compatible gear.
🔨 Superior Tensile Strength via Secondary Forging
Our advanced secondary forging process deeply optimizes the internal grain structure of the tungsten core. This results in much higher tensile strength and fatigue resistance, withstanding significant impact without snapping.
| Performance Metrics | Traditional Steel Wire | Fiberglass | Our Ultra-Fine Tungsten Wire |
|---|---|---|---|
| Tensile Strength | Approx. 2,000 MPa | Approx. 3,400 MPa | Up to 3,500 – 4,000 MPa (Highest strength at equivalent diameter) |
| Mainstream Fabric Gauge | 13G – 15G (Bulky and thick) |
15G – 18G (Brittle, prone to snapping) |
18G – 21G (Ultra-lightweight & high tactile sensitivity) |
| Cut Protection Ceiling (ANSI / EN388) |
Difficult to exceed ANSI A6 standalone | Often requires blending; typically maxes out around A5 |
Enables max ANSI A9 / EN388 Level F (Delivers 6,000g+ heavy-duty cut defense) |
| Skin Friendliness | Heavy with a stiff, rigid feel when bending | High Risk (Micro-fractures cause severe skin irritation & itching) |
100% Skin-Friendly (Glass-fiber free, completely non-irritating) |
| Functional Versatility | Compromises dexterity; no touchscreen compatibility |
Highly fragile under repetitive bending; short service life | Touchscreen compatible, excellent fatigue resistance, extends glove lifespan by 50%+ |
Why Us?
Raw Materials
In China, only less than 1% of manufacturers of tungsten start with raw materials production. Fortunately, we are one of these few manufacturers. The overall particle uniformity of APT raw materials we use is better than that of other companies in the market, which can guarantee the overall quality.
Yolo: Uniform particle size
Some others particle
Flaw Detection
Yolo will have corresponding inspection for each process. 100% flaw detection to the 0.39mm thick wire end to confirm the crack. Under flaw detection, there are Grade A (eg: 2 crack points per 100 meters), B, C Grade. Any level wire below C will be removed, since the more cracks, the more easily the yarn are broken during processing.
Drawing Process
Yolo’s advanced drawing equipment
Many other manufacture’s traditional equipment
A rolling mill introduced from Germany, which it can be deeply process the rod core, which can make the inside struction more uniform. Unlike the early traditional technology, are mainly surface processing.
