Tungsten-Nickel-Iron Alloy Earth-Penetrating Munition Product Introduction

I. Product Overview

In modern warfare, the protective capabilities of underground military facilities continue to advance, imposing higher demands on the penetration performance of earth-penetrating munitions. Our tungsten-nickel-iron alloy earth-penetrating munition, utilizing high-performance tungsten-based alloy as its core material, has emerged as a strategic-level weapon for striking deeply buried hardened targets. It excels in kinetic energy penetration, impact resistance, and high-temperature stability, making it suitable for conventional warfare, counter-terrorism operations, and precision destruction of critical targets.

Tungsten-nickel-iron alloy is a high-density material with tungsten (accounting for 90%-95%) as the primary component and nickel/iron as binder phases, achieving a density of 17-18.5g/cm³ (approximately 2.3 times that of steel). Its unique "tungsten particle-binder phase" microstructure endows the material with ultra-high strength (tensile strength ≥1200MPa) and excellent toughness (elongation ≥8%). During high-speed impact with hard targets like concrete and rock, it maintains structural integrity while maximizing kinetic energy transfer through its high density, enabling deep penetration.

II. Core Advantages

(1) High Density Empowerment: Enhanced Penetration Efficiency

• Significant Kinetic Energy Advantage: For the same projectile volume, the mass of tungsten-nickel-iron alloy exceeds that of steel cores by over 130%. When the projectile impacts targets at speeds of Mach 3-5, its kinetic energy output per unit area far surpasses traditional steel/ depleted uranium earth-penetrating munitions, enabling penetration of 20-30 meters of reinforced concrete or over 50 meters of soil.
• Superior Trajectory Stability: The high-density material concentrates the center of mass, improving wind deflection resistance by 40% during flight. Combined with aerodynamic design, it achieves a hit accuracy error ≤0.5 meters (CEP, Circular Error Probable), ensuring vertical impact and maximizing penetration depth.

(2) Strength-Toughness Synergy: Impact Resistance Without Fragmentation

• Exceptional Dynamic Strength: Fabricated via ultra-high-pressure compaction (≥200MPa) and vacuum sintering (1450-1500℃), the alloy forms a uniform "tungsten particle-binder phase" network structure. Under instantaneous impact stresses of 3000-5000MPa, it maintains projectile integrity, avoiding fragmentation or blunting issues common in traditional steel cores.
• Toughness Buffering Design: Nickel-iron binder phases (5%-10%) absorb partial impact energy through plastic deformation during collision, effectively mitigating stress concentration between tungsten particles. This ensures the projectile remains unbroken when penetrating multi-layer hardened structures (e.g., concrete-steel composite layers).

(3) High-Temperature Tolerance: Stability in Extreme Environments

• Excellent Ablation Resistance: During penetration, frictional heat elevates the projectile surface temperature to 800-1200℃. Tungsten-nickel-iron alloy, with a melting point (≈1700℃) far higher than steel (1500℃) and an oxidation rate only 1/5 that of steel, withstands the high-temperature challenge of continuous penetration through 5-8 concrete layers, avoiding kinetic energy loss from surface melting.
• Optimal Thermal Stress Compatibility: The alloy’s thermal expansion coefficient (≈4.5×10⁻⁶/℃) closely matches that of common explosives (e.g., TNT) and fuze materials, maintaining structural coordination among the projectile, explosive charge, and fuze under drastic temperature changes to ensure reliable detonation.

III. Quality Assurance System

(1) Full-Process Manufacturing Control

• Raw Material Selection: Uses spherical tungsten powder (5-15μm particle size) with purity ≥99.95%, and nickel/iron powders with oxygen content ≤0.02% to ensure alloy uniformity. Each batch undergoes laser particle size analysis and oxygen/nitrogen/hydrogen content testing.
• Forming & Sintering Optimization: Cold Isostatic Pressing (CIP) achieves uniform green density (deviation ≤1%). Vacuum sintering with hydrogen protection (dew point ≤-60℃) prevents oxidation. Post-sintering Hot Isostatic Pressing (HIP) eliminates internal micro-pores, achieving density ≥99.5%.
• Precision Machining: Five-axis CNC lathes and EDM forming technology ensure projectile shape tolerance ±0.05mm (key components like the nose cone angle tolerance ±0.1°) and surface roughness Ra≤0.8μm, guaranteeing consistent aerodynamic performance.

(2) Rigorous Performance Testing

• Impact Simulation Tests: Accelerated via gas guns (muzzle velocity 1000-1800m/s) in ballistic ranges, projectiles strike 40MPa high-strength concrete targets (2% steel reinforcement ratio). High-speed photography and stress sensors record deformation and penetration depth, with a required depth deviation ≤3%.
• High-Temperature Ablation Tests: Simulates 800-1200℃ environments in plasma high-temperature furnaces to measure surface mass loss rate (≤0.5g/cm²·h required).
• Fatigue Life Testing: Subjected to 100,000 vibration impact tests (50-500Hz frequency, 100g acceleration) to ensure no structural cracks after long-term storage.
