The industrial economy of the Russian Federation has undergone a massive transformation toward technological sovereignty, high-end mechanical engineering, deep-well energy exploration, and domestic aerospace resilience. Within this expanding industrial ecosystem, high density tungsten bars (known locally as heavy tungsten alloys or “Высокоплотные вольфрамовые сплавы”) occupy a critical strategic position. Containing between 90% and 97% pure refractory tungsten combined with nickel, iron, or copper binders, these heavy sintered alloy bars provide an unparalleled combination of maximum theoretical density (17.0 to 18.6 g/cm³), superior gamma/X-ray attenuation, high modulus of elasticity, and remarkable thermal shock resistance.
Specialized sinker bars, MWD/LWD directional drilling collars, and gamma-ray logging housings for harsh Siberian and Arctic permafrost drilling operations.
Compact dynamic counterweights, vibration dampening bars, and flight surface balancing components engineered for Russian commercial and transport aircraft.
High-density non-toxic collimators, PET syringe shields, and reactor inspection weights serving Rosatom research facilities and medical radiology hubs across Russia.
Russian industrial hubs — spanning the Central Federal District (Moscow, Kaluga), the Volga industrial corridor (Samara, Nizhny Novgorod, Kazan), the Ural metallurgical belt (Yekaterinburg, Chelyabinsk, Perm), and Western Siberia (Tyumen, Surgut) — have generated unprecedented demand for reliable, high-specification tungsten alloy billets, round bars, and rectangular blocks. The critical market factors include:

| W95NiFe (Class 3) | 95% W, 3.5% Ni, 1.5% Fe | 18.00 – 18.25 | ≥ 800 – 980 | 7 – 15 | Anti-vibration boring bars, medical linear accelerator collimators |
| W97NiFe (Class 4) | 97% W, 2.1% Ni, 0.9% Fe | 18.40 – 18.60 | ≥ 820 – 1000 | 5 – 12 | High-density nuclear shielding blocks, precision defense fittings |
| W90NiCu (Non-Magnetic) | 90% W, 6% Ni, 4% Cu | 17.00 – 17.20 | ≥ 650 – 780 | 6 – 15 | Magnetic sensitive logging probes, electron beam targeting, aerospace sensors |
| W95NiCu (Non-Magnetic) | 95% W, 3% Ni, 2% Cu | 18.00 – 18.20 | ≥ 680 – 820 | 4 – 12 | Non-magnetic shielding chambers, specialized analytical instrumentation |
We supply high density tungsten bars in round, square, hexagonal, and custom contoured cross-sections to Russian industrial consumers. Dimensional capabilities include outer diameters from Ø2.0 mm up to Ø350 mm and lengths up to 1,200 mm. Surfaces can be delivered as sintered unground (black surface), centerless ground (±0.01 mm precision), polished (Ra < 0.4 μm), or fully CNC-machined according to customer drawings.
Each delivery is accompanied by complete mill test certificates (EN 10204 3.1) stating chemical composition (ICP analysis), bulk density (Archimedes method), tensile yield strength, elongation, and ultrasonic non-destructive testing (NDT) reports to guarantee absolute freedom from internal porosity or micro-cracks.
Direct containerized rail freight from Tianjin and Zhengzhou through Manzhouli / Zabaikalsk border crossings directly to Vorsino / Moscow rail hubs in 14-18 days.
Containerized sea freight to Vladivostok or Vostochny ports connected with Trans-Siberian railway transport reaching Urals and Central Russia safely and economically.
Urgent tooling blanks, medical shielding parts, and emergency prototypes flown directly to Moscow Sheremetyevo (SVO) or St. Petersburg Pulkovo (LED) in 3-5 business days.
