Advantages Introduction
1. Ultra-High Tungsten Purity: Our tungsten-based components, like Tungsten Point Contact and Pure Tungsten Contact, have a tungsten content of ≥99.95%, exceeding the industry - common ≥99.5%. This high-purity tungsten ensures excellent electrical conductivity and thermal stability, laying a solid foundation for reliable performance in electrical contacts and rivets.
2. Exceptional Magnetic & Physical Properties: With a coercivity of ≤250A/m (industry standard ≤350A/m) and a density of ≥19.25g/cm³ (industry average ≥19.0g/cm³), our products exhibit superior magnetic characteristics and structural integrity. They are ideal for high-precision applications such as Electrical Tungsten Contact Rivets in complex circuits.
3. Optimal Hardness for Processability: The hardness of our tungsten alloys is controlled within the 350 - 450HV range, compared to the industry's 300 - 400HV. This optimal hardness balance allows for easier machining and forming while maintaining sufficient strength, perfectly suiting the production of Tungsten Brazed Rivets and other precision components.
4. Refined Grain Structure: Featuring a Grade 7 grain size (industry standard Grade 5), our tungsten materials have a more uniform and refined microstructure. This uniformity guarantees consistent mechanical and electrical performance across different batches, reducing performance variations in end products like relays and switches.
Tungsten Contact Stamping Production Process
1. Mold Design & Fabrication (for Tungsten Contact)
Using high-grade mold steel (e.g., Cr12MoV with specialized heat-treatment), hardness reaches HRC60-65.
Mold lifespan can exceed 900,000 cycles.
Cavity precision is controlled within ±0.003mm.
2. Tungsten Contact Stamping Operations
| Process Step | Processing Detail | Precision control |
| Initial Stamping | Basic shaping of tungsten blanks | ±0.03mm |
| Fine Stamping | Contouring Tungsten Steel Contact features | ±0.02mm |
| Final Stamping | Finish forming the Pure Tungsten Contact and edge smoothing | ±0.01mm |
3. Process Advantages
Production efficiency boosted by 30% vs. traditional methods.
Material utilization rate hits 93%, minimizing waste.
Consistency of Tungsten Steel Contact / Pure Tungsten Contact is greatly enhanced, ensuring stable conductivity for end-products like relays.
4. Key Process Control Measures
1. Dimensional Accuracy: Daily checks with high-precision CMM; critical dimensions require CPK≥1.7.
2. Surface Quality: Strict control to Ra≤0.6μm, no scratches or oxidation.
3. Material Integrity: Regular testing for tungsten content (≥99.95% for Pure Tungsten Contact) and alloy composition compliance.
