1. Generally speaking, the manufacturing materials for shrapnel should have high elastic limit, fatigue limit, impact toughness, and good heat treatment performance. Commonly used materials include carbon shrapnel steel, alloy shrapnel steel, stainless shrapnel steel, as well as copper alloy, nickel alloy, and rubber.
2. The manufacturing methods for shrapnel include cold rolling and hot rolling. The cold rolling method is generally used for shrapnel wire with a diameter less than 8mm, and the hot rolling method is used for wire with a diameter greater than 8mm. Some fragments need to undergo strong pressure or shot peening treatment after production, which can improve the load-bearing capacity of the fragments.
3. Shrapnel is a widely used elastic component in the mechanical and electronic industries. When loaded, shrapnel can generate significant elastic deformation, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the shrapnel disappears and returns to its original state, converting deformation energy into mechanical work or kinetic energy.
