Titanium: An Indispensable Material for Weapons
Aug 12, 2025
Titanium alloys have gained widespread application in the weapons industry, becoming an indispensable material. Titanium enhances weapons' power and enhances their effectiveness. Titanium-based weapons are not only lightweight and maneuverable, but also offer increased power, making them particularly suitable for airborne and assault troops. Titanium alloy mortar base plates are over 50% lighter than steel. Titanium alloys are a superior material for mortar barrels, base plates, gun barrels, and gun mounts, and are also an excellent choice for protective clothing and helmets.
Since the industrialization of titanium and its alloys in the mid-1940s, the United States and the Soviet Union have been interested in and researching their applications in weapons. The Watertown Arsenal in the United States has pioneered significant research in the application of titanium alloys in weapons, making it the world's largest and most advanced institution for researching titanium alloys in weapons. In 1955, the U.S. weapons industry used 57 tons of titanium, 281 tons in 1961, and 1,040 tons in 1971. It is estimated that this figure reached 2,100 tons in 2020. Because it is a non-war period, the growth rate is not rapid.
Application in Artillery
Titanium and titanium alloys are important materials for the manufacture of artillery structural components. Since the 1950s, they have been used in some world-renowned artillery pieces. The barrel, chamber, nozzle, and firing piston of the M28 120mm Crockett recoilless rifle, manufactured in the United States in 1950, were forged and extruded from a Ti-6Al-6V-2Sn-0.5Fe-0.5Cu alloy. The entire rifle weighed 68kg, 34.9% lighter than the 104.4kg steel version. Disassembled, it could be easily carried by five men. Mass production began in 1961, equipping infantry, paratrooper, mechanized infantry, tank, and airborne battalions. Its advantages included compact size, light weight, high power, high mobility, and ease of camouflage. Ti-6Al-6V-2Sn-0.5Fe-0.5Cu is an (α+β) alloy. Its mechanical properties in the annealed state include a tensile strength of 1098 MPa, a yield strength of 1030 MPa, an elongation of 13%, a reduction of area of 37%, and a Brinell hardness of 34. In the 1970s, the barrel was manufactured using Ti-6Al-4V-2Sn titanium alloy, while the chamber, nozzle, and firing piston were constructed from Ti-6Al-4V, Ti-7Al-4Mo, and Ti-5Al-1.5Fe-1.4Cr-1.2Mo titanium alloys. The entire gun weighed only 49 kg, enough for four men to carry while running. The T66 76mm gun's tailstock and gun carriage, after being converted to titanium alloy, were 93.55 kg lighter than steel, weighing only 142.9 kg. The titanium alloy main frame of the field gun was 42% lighter than steel. Later, the United States used industrially pure titanium for the base plate of the T227 81mm mortar, making it 50% lighter than steel, weighing only 10.9 kg. The gun's breech block, also made of titanium alloy, connects the barrel to the base plate. Hundreds of test firings were conducted on both dirt and gravel surfaces, achieving positive results. After the T227 81mm mortar switched to a titanium base plate, its weight dropped to 34kg and its range increased to 4,500m. A steel version weighed 42.25kg and had a range of 3,600m. This not only reduced its weight by 20%, increased its range, but also significantly improved its maneuverability.
Japan's 155mm pursuit gun base plate switched to a titanium alloy from Kobe Steel, reducing its weight by approximately 50%. The base plate is welded from 5mm and 8mm Ti-6Al-4V alloy plates. Tests have shown excellent weld quality, fully meeting combat requirements. Japan's 100mm mortar base plate, made of integrally stamped TA7 alloy, is 10kg lighter than its steel counterpart. The design was finalized in 1981, and production began in 1983. The 82mm mortar, which entered service in 1984, switched to a titanium alloy for the barrel, base, and bracket, making it 16.6kg lighter than steel. On January 31, 2007, the U.S. Army Times reported that the new 155mm M777 howitzer was the first ground combat system to be manufactured using titanium alloy. It was approximately 3,150 kg lighter than the obsolete M198 gun, a weight reduction of nearly 50%. This reduction in weight did not affect the gun's range or accuracy, but significantly improved its mobility.
Helmets, body armor, and other equipment
From 1959 to 1961, the United States unsuccessfully spun the standard M-1 helmet using Ti-6Al-4V and Ti-5Al-2.5Sn titanium alloys. Later, they switched to Ti-4Al-3Mn titanium alloy and explosive forming, achieving success. The result was a titanium helmet weighing only 0.794 kg to 1.02 kg. While providing the same ballistic protection as a steel helmet, the titanium helmet was 0.45 kg lighter than the standard steel helmet. The United States manufactures bulletproof vests using 25.4mm thick sheets composed of 10 layers of nylon and one layer of Ti-5Al-2.5Sn titanium alloy. Weighing only 3.86kg, they offer protection against artillery shells, grenades, and mine fragments, but not 7.62mm rounds.
The muzzle brake of the Russian Union 152mm twin-barreled self-propelled gun is made of titanium alloy. It features two barrels that alternate during firing, offering a high rate of fire and a powerful firepower of 15-18 rounds per minute. It is also highly maneuverable, capable of off-roading, and possesses strong survivability.
China has been researching the application of titanium alloys in weapons manufacturing since the 1970s, with significant results. TC9 titanium alloy, a Ti-0.2Pd α-alloy, is used in the annealed state to manufacture the servos and frames of anti-tank missiles. TC4 titanium alloy has achieved excellent results in the Type 85 anti-aircraft machine gun muzzle brake. Later, the use of precision-cast ZTC4 alloy in place of TC4 alloy extruded bar achieved even better results, increasing material utilization from 18% to 94% and saving significant cutting costs – killing two birds with one stone. TC4 is a commonly used, high-performance Ti-6Al-4V alloy of the α+β type, used in the annealed state. Titanium-made lightweight flamethrowers, with a range of up to 70 meters, are a close-range light weapon that is over 3 kg lighter than steel and can be manufactured from alloys such as commercially pure titanium and Ti-3Al-2.5V.
