Titanium Alloy in Armored Vehicle
Modern armored vehicles must not only have strong protection capabilities on the battlefield, but also take into account mobility, fuel efficiency and combat performance in complex environments. This places higher requirements on lightweight and high strength materials.
Why choose titanium alloy?
The reason why titanium alloy is an ideal material in armored vehicle manufacturing is mainly based on the following key advantages:
- While the strength of titanium alloy is close to that of high-strength steel, its density is only about 60% of that of steel. It can significantly reduce the weight of the vehicle body without sacrificing protective performance, thereby improving maneuverability and fuel efficiency.
- Titanium alloys have excellent weather resistance and corrosion resistance, and are particularly suitable for armored vehicles operating in water, humid, hot or high-salt environments, extending their service life and reducing maintenance costs.
- Titanium alloys can be formed and welded through a variety of processes, making it easy to manufacture complex structures and realize a variety of design schemes to meet the modularization and customization needs of modern armored vehicles.
- Certain titanium alloys can provide effective ballistic protection at relatively small thicknesses, especially exhibiting superior energy absorption capabilities when facing fragments, bullets or blast waves.
Key titanium alloy components for armored vehicles
Armored vehicle roofs and hatches
The roof and hatch covers of armored vehicles are key structures that protect the personnel inside the armored vehicle from attacks from above. They usually need to balance a good observation field of view and ease of operation. Especially when encountering artillery attacks or debris attacks, the hatch covers need to have high bullet and impact resistance.
Compared with traditional aluminum alloys, Ti-6Al-4V (MIL-T-9046J) titanium alloy reduces weight by about 35%. While maintaining high strength, it significantly improves anti-ballistic performance, thereby effectively enhancing the maneuverability and safety of the entire vehicle.
In actual application, the U.S. Army M2 Bradley infantry fighting vehicle has upgraded the commander's hatch. The original aluminum alloy hatch has been replaced with Ti-6Al-4V titanium alloy, which significantly improves the vehicle's protection capabilities.

Chalco Titanium Composite Armor Technology and Delivery Capabilities
Titanium-steel composite armor plate
Chalco uses processes such as explosive welding and hot rolling composite to firmly combine Ti-6Al-4V titanium alloy with high-strength armor steel to form a structurally stable titanium-steel composite armor plate.
This material has both the lightness and high strength of titanium alloy and the high hardness of steel. It can effectively resist mine explosions, IED impacts and penetration by medium-caliber kinetic energy bullets. It is suitable for use in key protection areas such as chassis, side armor and top hatches.
Titanium-steel composite plates are particularly suitable for scenarios where the weight of the vehicle needs to be controlled while improving the protection level, such as light tactical vehicles and urban combat platforms.
Titanium-ceramic composite armor plate
To resist the impact of high-speed armor-piercing projectiles (such as APDS and API), Chalco provides titanium-ceramic composite plates, which are suitable for high-protection areas such as the front of the turret and the front of the vehicle.
The structure usually consists of boron carbide or alumina ceramics as the front layer and titanium alloy as the back plate. The ceramic layer is responsible for breaking the bullet and dissipating energy, while the titanium layer absorbs residual impact and prevents penetration.
Chalco can also assist customers in designing protective layer structures, including thickness ratio, layer layout and ballistic impact simulation, to optimize the balance between protective effect and cost.
