Guangxi Chentian Metal Products Co., Ltd

Model Number: 90 Brand Name: CHENTIAN Key Specifications/Special Features: The most outstanding property of tungsten heavy alloy is high proportion, also called as high densityThe density of tungsten heavy alloy can reach 18g/cm, which is higher than steel (7.8g/cm) by 2.3 timesSo the fracture surface of bullet has high density which highly improving speed of bullet and penetration to steel plate during flyingTungsten alloy machine gun bullet is kind of machine gun bullet which has good properties, developed form 1970'sThe warhead of machine gun bullet has the properties of high initial velocity, low trajectory, short flying time, high accuracy, high penetration and more, by adopting decorticating theory, new structure and material of tungsten heavy alloyIt can deal with high-speed target efficientlyThe fracture surface of bullet has high densityThe tungsten alloy core has good ductility, which is contrary to the broken of hard steel or tungsten carbide core during penetrationTungsten alloy machine gun bullet has excellent property of second penetration and penetrates to armor in splash typeTungsten alloy machine gun bullet has significant penetration to composite armor which has big impact angle, or layered constructionTungsten alloy core has been widely adopted for large caliber bullet or small caliber shell, as ammunition to target which has light armor such as panzer or attack helicopterChinese type 84 12.7mm tungsten alloy machine gun bullet is equipped with type 77 12.7mm anti-aircraft machine gun and is in common use in type 54 12.7mm anti-aircraft machine gun
The quality of warhead is 28g and quality of core is 22g which is 78.6% of warhead
The diameter of core is 7.9mm
Sub-caliber ratio (core diameter to warhead diameter) is 0.62
Initial velocity of bullet is 1150m/s
It can penetrate 15mm homogenous steel alloy plate in 45° impact angle from distance of 20m
The maximum distance of penetration to 20mm homogenous steel alloy plate is 150m in 45° impact angle
However, Chinese type 54 12.7mm armor-piercing incendiary (API) ricochets from distance of 9.5m
It can only penetrate 15mm steel plate in 30° impact angle from distance of 830m and penetrate 20mm steel plate from distance of 125m
So, 12.7mm tungsten alloy machine gun bullet has better penetration to steel plate in big impact angle
