Ultra-hard Core Precision Measuring Alloy Round Bar
The tungsten steel piston rod, designed for ultra-high pressure, strong corrosion, and wide temperature change conditions, reconstructs the pressure measurement accuracy standard with 1900HV hardness + mirror-grade polishing (Ra≤0.05μm). In key areas such as deep well drilling, geothermal monitoring, and aviation hydraulics, it becomes the uncompromising rigid spine of the pressure gauge transmission system.

Material-science:
▸ Base material: 94% tungsten + 5.6% cobalt nano-sintered alloy
▸ Hardness: 92HRA
▸ Compressive strength: >6300 MPa
Industrial-scenarios:
► Energy exploration
- Shale gas fracturing wells
- Supercritical geothermal wells (450℃/70MPa continuous operation)
► High-end manufacturing
- Closed-loop control of heavy hydraulic presses (response accuracy
0.01%FS)
- Vacuum cavity transmission of semiconductor dry etching equipment
► Special fields
- Deep-sea detector 10,000-meter pressure-resistant cabin
- Rocket fuel boost valve control system
