US Manufacturing
High-density tungsten heavy alloy (WHA) rods and bars engineered for defense, aerospace, medical, and industrial applications. Our WHA products are manufactured to ASTM B777 specifications in compositions including W-Ni-Fe (Class 1-4) and W-Ni-Cu alloys, with densities ranging from 17.0 to 18.5 g/cm³. Available in standard and custom diameters from 0.125" to 4.0", with lengths up to 48". All material is US-produced, ITAR registered, and DFARS compliant.

WHA serves the most demanding sectors. Kinetic energy penetrators and armor-piercing rounds depend on WHA’s density and hardness. Radiation shielding for medical linear accelerators and industrial gamma sources require non-magnetic W-Ni-Cu. Aerospace counterweights benefit from compact mass at tight tolerances. Vibration-dampening applications in precision machinery use WHA’s damping characteristics. We stock ASTM B777 Class 1 (lower hardness, higher ductility) through Class 4 (maximum hardness), allowing engineers to select the exact mechanical property match for their end-use.
Every bar is tested for density, ultimate tensile strength, yield strength, elongation, and hardness. Ultrasonic inspection detects internal voids. Dimensional tolerances held to customer print. MIL-T-21014 and AMS 7725 compliance certified. Full material certifications and test reports accompany each shipment. Traceability to lot number and melt heat. No exceptions for critical applications.
Our technical team handles alloy selection for your specific requirement: W-Ni-Fe for magnetic applications, W-Ni-Cu for non-magnetic systems, Class 1 for impact resistance, Class 4 for hardness. We answer composition questions, verify mechanical property requirements against ASTM standards, and coordinate with your procurement process. Custom blanket orders, scheduled shipments, and expedited lead times available for qualified buyers.
Our team will respond within 24 hours with pricing and availability information.
Material certification begins with density verification—critical for kinetic energy applications where mass efficiency determines performance. We measure via water displacement and compare to ASTM B777 density bands (17.0–18.5 g/cm³). Tensile testing confirms yield and ultimate strength within class specification. Hardness testing (Rockwell B or Vickers) verifies heat treatment and composition. Elongation measurement ensures ductility meets class requirements. Ultrasonic inspection scans each bar for internal voids, segregation, and material defects. Dimensional measurement confirms diameter, length, and straightness to tolerance. Surface inspection checks for cracks, laps, or surface contamination. Test reports document every result; certificates of compliance accompany every shipment. MIL-T-21014 and AMS 7725 testing protocols are incorporated as standard. Traceability extends to raw tungsten lot, melt heat, and final test date. For critical defense and aerospace contracts, we provide full documentation packages: material certs, test reports, CoC, and traceability records. Third-party audits available upon request.
