Tungsten Copper Liner
What is Liner?
Liner is called the bomb's heart. Length armor penetration capability and jet jet, jet and target material density than the square root, and the jet is proportional to the square of the speed; also the stability, continuity, post oak size and other factors related to the jet. Liner wall thickness is 2% to 3% of the diameter of the mouth, medium-caliber shaped charge liner thickness of about 2mm.
What is Tungsten Copper Liner
With further research, there has been a composite liners (such as tungsten copper alloy) It is the different properties of metal or alloy, in accordance with the design requirements of the Liner compounded play the comprehensive advantages. Compared with a single metal liners, energy conversion and absorption mechanism is more reasonable, more fully utilization of chemical energy, armor and better performance, lower cost also has broad development prospects.
Tungsten copper shaped combination of high density and ductility of tungsten copper, compared to copper liners have higher power and armor shaped effect. The disadvantage is that tungsten and copper can not dissolve each other, and because of the density difference between the two large, easy to form when gravity segregation caused by compression molding liners inhomogeneous density distribution.
Tungsten copper alloy as an ideal material for liners, but there is more in the preparation process issue, tungsten copper alloy bonding strength is poor, molding material difficulties; its wear deep fried sensitive to high variability, it should only lower Fried use under high conditions.
You can improve the disadvantage of tungsten copper shaped by the following:
1, a conventional tungsten copper alloy density difference obtained by the method, the uneven density distribution, a more effective method for mixing powder or the preparation of molding can be used, including isostatic pressing and the like.
2, changing the sintering temperature and obtain better bonding strength.
3, on the layered liners do question whether it will result in poor stability problems.
4, if the density and bond strength can be improved, and then use the company's strengths, the material is rolled into sheets, tungsten copper alloy Liner material prepared by spinning, stamping or forging methods.
