Titanium bar: an indispensable material for arms

Titanium alloy in the weapons industry has gained wide application, become an indispensable material, weapons with titanium, such as a tiger to add wings, more skillful. Titanium alloy weapons are not only light in quality, mobility, and rising power, especially suitable for airborne troops and assault troops, titanium mortar seat plate is more than 50% lighter than steel plate, titanium alloy is the manufacture of mortar tubes, seat plate, gun barrels, gun racks, etc. superior materials, but also the preparation of protective clothing and helmets of good materials.

Titanium and titanium alloys since the mid-1940s industrialized production, the United States and the Soviet Union began to pay attention to and study their application in weapons, the United States of America Watertown (Watertown) Ordnance Factory of titanium alloys in the application of weapons to do a lot of pioneering work, is the world's research on titanium alloys in the field of weapons application of the largest and most advanced units. 1955 U.S. Arms Industry with 57 tons of titanium. In 1961, 281 tons, 1040 tons in 1971, it is estimated that in 2020 has reached 2100 tons, because it is not a period of war, so the growth rate is not fast.


Application in artillery
Titanium and titanium alloys are important materials for the manufacture of structural parts for artillery, and have been used in some world-famous artillery pieces since the 1950s. The United States in 1950 manufactured M28 120mm Crockett (Crockett) recoilless gun barrel, chamber, nozzle and firing piston is used Ti-6Al-6V-2Sn-0.5Fe-0.5Cu alloy forging and extrusion and become, the whole quality of the gun 68kg, 104.4kg lighter than the steel gun 34.9%, split after 5 people can easily carry away, the mass production began in 1961, the mass production of titanium alloy,Titanium Bar, Titanium Sheet, Titanium Plate, Titanium Tube, Titanium Pipe and titanium fittings. In 1961, began mass production, equipped with infantry battalions, paratrooper battalions, mechanized infantry battalions, tank battalions and airborne divisions, with a small size, light weight, high power, high mobility and easy to camouflage and so on. ti-6Al-6V-2Sn-0.5Fe-0.5Cu is a (α + β) type alloy, annealed mechanical properties: tensile strength 1098MPa, yield strength 1030MPa, elongation 13%, section shrinkage 37%, Brinell hardness 34.

Helmets, body armor and other equipment
1959-1961 U.S. with Ti-6Al-4V, Ti-5Al-2.5Sn titanium alloy spinning M-1-type standard helmets unsuccessful, and then switched to Ti-4Al-3Mn titanium alloy with the explosion molding process to achieve success, the quality of only 0.794kg-1.02kg, in terms of bulletproof effect, titanium helmets and helmets, but titanium helmets are lighter than the standard steel helmets 0.45kg.
The United States with 25.4mm thick by 10 layers of nylon and 1 layer of Ti-5Al-2.5Sn Titanium Alloy Sheet composed of plate manufacturing bulletproof undershirt, its quality is only 3.86kg, can prevent artillery shells, grenades, landmine fragments, but can not prevent 7.62mm gunfire.
The muzzle brake of the Russian Union 152mm double-barreled self-propelled gun is made of titanium alloy, which has two barrels, alternating when firing, fast firing speed, strong firepower, up to 15-18 rounds per minute; maneuverability, cross-country capability, and strong survivability.


China since the 1970s began to study the application of titanium alloy in the manufacture of weapons, with remarkable results. With TC9 titanium alloy manufacturing anti-tank missile rudder and frame, it is a Ti-0.2Pd alpha alloy, in the annealed state application; with TC4 titanium alloy manufacturing 85-type anti-aircraft machine gun retractor achieved very good results, and later, precision casting ZTC4 alloy instead of the TC4 alloy extruded bar achieved better results, the material utilization rate from 18% to 94%, but also saves a lot of Cutting and machining costs, two birds with one stone.TC4 is a commonly used excellent performance Ti-6Al-4V alloy, α + β type, in the annealed state application. The lightweight flamethrower made of titanium has a range of up to 70m, which is a kind of light weapon at close range, and is more than 3kg lighter than the steel one, which can be prepared with industrial pure titanium, Ti-3Al-2.5V and other alloys
