Key Features & Benefits
Discover why our products are trusted by industries worldwide
Tight diameter tolerance for stable downstream coating
Fine diameter control helps maintain more stable wire behavior in diamond-wire production and downstream slicing processes where line consistency matters.
Higher strength and breaking load
Designed for photovoltaic processing routes that need higher tensile strength, reliable breaking load, and better resistance to wire failure during continuous production.
Better fit for thinner wafer trends
Finer wire specifications support modern wafer-thinning direction by helping reduce kerf loss and improve output efficiency in slicing applications.
Stable surface condition
Smooth appearance, controlled defects, and better winding quality help support downstream coating adhesion and more stable unwinding behavior.
Photovoltaic-focused specification range
Promoted specifications include fine and high-strength sizes aligned with current photovoltaic slicing programs, including 0.035 mm, 0.037 mm, 0.10 mm, and 0.11 mm.
Custom supply for different equipment and wafer programs
We can align wire performance targets such as breaking load, tensile strength, and supply condition to different process windows and equipment requirements.

Typical promoted specifications
The most commercially important photovoltaic tungsten wire sizes are the ones that help customers balance finer slicing with enough mechanical strength.
- 0.035 mm for mature fine-wire photovoltaic slicing programs
- 0.037 mm for lower silicon-loss direction with stronger load margin
- 0.10 mm for larger-size or higher-load slicing programs
- 0.11 mm for customers needing stronger adaptation to thicker or larger wafers
These sizes are where buyers usually compare breaking load, tensile strength, coil quality, and stability across batches.
Why photovoltaic buyers upgrade tungsten wire programs
In photovoltaic slicing, wire performance affects more than a single purchase price.
- Fine diameter control supports more stable downstream processing
- Higher strength reduces the risk of breakage during production
- Better surface quality helps coating and slicing consistency
- Stronger batch stability helps keep production windows predictable
- Finer wire strategies can support lower kerf loss and higher wafer output
Manufacturing and quality control for photovoltaic supply
Our tungsten wire production is controlled from raw material preparation through forming, drawing, precision finishing, and final inspection.
- Chemical composition control on tungsten content and impurity limits
- Diameter and tolerance inspection across the wire length
- Ovality, coil, and appearance review to reduce downstream instability
- Mechanical property checks such as breaking load, tensile strength, and torsion where required
- Surface-quality screening for oxidation, scratches, pits, and visible drawing defects
