National defense construction

Tungsten carbide (hard alloy), with its core advantages such as ultra-high hardness, high temperature resistance, wear resistance, impact resistance, and low coefficient of thermal expansion, precisely meets the stringent requirements of national defense construction for equipment with "extreme operating condition tolerance, high precision, and high reliability." It is widely used in key areas such as weapon manufacturing, ammunition production, military electronics, and aerospace defense support. Specifically:

In the manufacturing of core components for weaponry, tungsten carbide is a critical material. Wear-resistant rifling inlays and breechblock locking components in firearms and artillery are made of tungsten carbide, which can withstand the erosion of high-temperature, high-pressure propellant gases and high-frequency firing impacts, improving weapon service life and firing accuracy. Wear-resistant inlays in the track plates and road wheels of tanks and armored vehicles, relying on the high wear resistance of tungsten carbide, adapt to the wear requirements of driving in complex terrain, reducing the frequency of equipment maintenance.

Tungsten carbide plays a core role in ammunition production and damage components. Armor-piercing and high-explosive anti-tank (HEAT) projectiles use high-density tungsten steel (14-15 g/cm³) for their cores. Its high hardness and high kinetic energy penetration effectively penetrate armored targets. Precision components of ammunition fuses (such as firing pins and valve cores) are formed using tungsten steel molds, with dimensional tolerances controlled within ±0.01 mm to ensure reliable fuse activation. Precision forging molds for projectile casings and bodies use tungsten steel-based composite materials, resistant to high-temperature creep, ensuring mass production precision.

In military electronics and guidance systems, tungsten steel ensures stable performance. Miniature antennas and waveguide components in radar and missile guidance systems are formed using precision tungsten steel molds. Its low coefficient of thermal expansion ensures dimensional stability and signal transmission accuracy in complex electromagnetic environments. In the forming molds for sensitive elements of military sensors (such as infrared and pressure sensors), the high rigidity of tungsten steel prevents component deformation and improves detection sensitivity. Miniature connectors and terminals in military computers and communication equipment are mass-produced with high precision using tungsten steel stamping dies, ensuring reliable insertion and removal in harsh battlefield environments.

In addition, protective armor inserts in defense engineering, hydraulic valve cores in military machinery, and wear-resistant inserts for precision transmission gears are all made of tungsten steel. Its corrosion resistance and radiation resistance characteristics can adapt to extreme environments in multiple fields such as sea, land, air, and space, fully supporting the high performance, high durability, and battlefield survivability of defense equipment.
