Zhuzhou Jiuding Metal Technology Co., Ltd. High-Density Tungsten Nickel Iron (W-Ni-Fe) Alloy Cylinders are high-specific-gravity structural cylindrical parts developed for industrial counterweight balancing, vibration damping, gravity weighting and mechanical stabilization scenarios. Manufactured via mature PM powder metallurgy compression forming and liquid-phase sintering technology, our tungsten alloy cylinders strictly comply with Mil-T-21014 US military standard, ASTM B777-99 / ASTM B777-15 (R2020) industrial specifications, and GB/T 1804-2000 general dimensional tolerance standard. Available in mainstream 90W-Ni-Fe and 95W-Ni-Fe grades, these high-density tungsten cylinders support full-size custom processing to meet diverse industrial equipment assembly requirements.

W-Ni-Fe alloy cylinders feature ultra-high density ranging from 16.85 g/cm³ to 18.35 g/cm³, far exceeding the specific gravity of steel, copper and conventional alloy materials. The high-mass compact structure realizes precise gravity matching and effective vibration suppression in limited installation space, greatly improving mechanical operation stability and structural coordination. We support Sintered and Polished optional surface states and full non-standard customization of diameter, length and tolerance. All finished products can be provided with EN 10204 3.1 inspection certificates, fully compliant with RoHS, REACH and global industrial procurement standards.

Powder Metallurgy (PM) Manufacturing Process

All high-density tungsten nickel iron alloy cylinders adopt professional PM powder metallurgy pressing and sintering integrated process, which fundamentally solves the problems of uneven density, internal pores and unstable performance of traditional casting and forging parts, ensuring high consistency of batch cylindrical products:

• Precision Alloy Proportioning & Mixing: High-purity tungsten, nickel and iron raw materials are proportioned according to standard 90/95 tungsten grades. Uniform powder mixing ensures consistent alloy composition and stable physical and mechanical properties of each cylinder blank.

• High-Pressure Die Compression Forming: Adopt professional powder metallurgy pressing equipment for integral cylindrical green blank forming, with regular shape, uniform density and reasonable machining allowance, laying a foundation for subsequent precision finishing.

• High-Temperature Liquid-Phase Sintering: Under precise temperature and atmosphere protection, high-density sintering is completed to realize tight bonding between alloy particles, significantly improving material compactness, structural rigidity and overall stability.

• Precision Finishing & Custom Machining: Support turning, grinding, straightening and length cutting according to customer requirements. Provide original Sintered surface and high-precision Polished surface treatment to meet different assembly and appearance standards.

The standardized PM production process enables our tungsten nickel iron cylinders to feature uniform microstructure, stable density distribution and excellent machinability, supporting mass production and personalized customized processing.
