Tungsten powder—19.3 g/cm³ density, 3,422°C melting point—is the go-to material for high-performance aerospace and defense applications. We stock pure tungsten (99.95%+ W), W-Ni-Fe heavy alloys, W-Ni-Cu, and W-Cu blends in particle sizes from sub-micron through 45–150 µm, tailored for powder metallurgy, additive manufacturing, and dense component production. Applications include radiation shielding, kinetic energy penetrators, high-temp furnace hardware, electrical contacts, and AM feedstock. US-produced, ITAR registered, DFARS 252.225-7014 compliant, AS9100D and ISO 9001:2015 certified with full supply chain traceability.

RFQ-ready support. Our engineers review your material specs, lead times, and testing requirements. No generic quotes—sourced for your exact application.
Tungsten's unmatched density and melting point drive demand across aerospace, defense, medical, nuclear, and electronics. Defense applications rely on W-based dense alloys for kinetic penetrators, radiation collimation, and vibration damping in guidance systems. Medical and nuclear sectors use tungsten shielding for X-ray and gamma-ray attenuation in compact geometries. Electronics manufacturers specify tungsten for electrical contacts, heat sinks, and semiconductor carriers where thermal conductivity and density meet reliability demands. Additive manufacturing increasingly calls for tungsten feedstock—our AM-grade powders are optimized for laser sintering and meet flowability and tap density specs for equipment compatibility.
Every lot undergoes ICP-OES analysis for tungsten purity and trace element verification. We run GDMS for ultra-low impurity requirements, LECO carbon/sulfur analysis, and particle morphology assessment via SEM. FSSS (Fisher Sub-Sieve Sizer) and BET surface area confirm powder behavior for sintering; laser diffraction validates particle size distributions. AM-grade material includes tap density, flowability (Hall flow), apparent density, and oxygen content testing to spec. Full test reports, material safety data sheets, and traceability documentation accompany each shipment. Certifications include AS9100D audit reports and DFARS compliance attestation.
Ordering tungsten powder means understanding your timeline, spec demands, and batch size. We maintain stock of common grades and sizes; custom milling and sizing add 2–4 weeks lead time. Our engineering team reviews your material specs, particle size requirements, and testing scope before quoting. We handle DFARS sourcing documentation, provide certified-origin paperwork, and coordinate with your quality group on inspection and acceptance protocols. Technical support extends post-delivery—we're here when you need density calculations, sintering parameters, or alloy blend recommendations.
Our team will respond within 24 hours with pricing and availability information.
Tungsten powder grades break down by composition and intended process. Pure tungsten (W 99.95%+ with controlled trace elements) suits high-temperature applications and radiation shielding where maximum density is critical. W-Ni-Fe (typically 90W-6Ni-4Fe) and W-Ni-Cu (90W-7Ni-3Cu) heavy alloys balance density with mechanical strength and machinability—standard for kinetic penetrators, vibration control, and precision-finished components. W-Cu blends (up to 90W-10Cu) offer improved electrical and thermal conductivity for contacts and heat management. Particle size selection depends on process: sub-micron powders enable fine sintering and additive manufacturing; 5–15 µm supports powder metallurgy pressing and conventional pressing of complex geometries; coarser fractions (45–150 µm) reduce sintering time and improve green density. Supply chain considerations are substantial. Approximately 80% of global tungsten ore comes from China; most refined powder follows. For DFARS 252.225-7014 compliance and allied-nation sourcing, domestic powder sourcing eliminates geopolitical supply risk and simplifies compliance documentation. We produce and stock tungsten powders in the US, ITAR registered, with full chain-of-custody traceability—meeting defense contractor procurement mandates without foreign sourcing delays or restrictions.
Tungsten powder testing requirements vary by application and classification. Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is standard for bulk composition and trace impurity detection (Fe, Ni, Cu, Mo, Re, O, etc.). When sub-ppm impurity control is critical (e.g., nuclear shielding or high-reliability electronics), Glow Discharge Mass Spectrometry (GDMS) provides superior sensitivity. LECO carbon, nitrogen, and sulfur analysis ensures interstitial purity; laser diffraction confirms particle size distribution and validates sieve data. Powder Metallurgy grades receive FSSS (Fisher Sub-Sieve Sizer) and BET surface area measurement to predict sintering behavior. Additive Manufacturing powders add tap density, apparent density, flowability (Hall flow time), and oxygen content testing—parameters that directly affect AM equipment performance and part density. AS9100D certification requires documented test procedures, qualified lab equipment, and full material traceability. We maintain individual lot records linking tungsten ore source, refinement batch, and final powder batch. Custom certifications (e.g., NADCAP for specialty aerospace work) are coordinated with your quality requirements. DFARS attestation and certified-origin paperwork accompany defense orders—your compliance document is ready when your RFQ closes.
