The commonly used materials for alloy hammerheads include high manganese steel, high chromium cast iron, and low-carbon alloy steel. High manganese steel has good toughness, good processability, and low price. Its main characteristic is that under the action of large impact or contact stress, the surface layer will rapidly undergo work hardening.

The bimetallic composite hammer head adopts the lost foam dual liquid composite casting process, which is formed in one go. The composite surface is made of high-strength and tough steel. The hammer head is made of high chromium alloy, matched with multiple alloys, and is loaded with precious elements such as molybdenum, vanadium, and niobium. The grain is refined after modification during melting.

Choosing appropriate materials is the basic way to improve the lifespan of hammer heads. Due to the varying degrees of impact and cutting wear experienced by the hammer during reuse, high toughness and hardness requirements are placed on the materials used.

Heavy alloy hammers should be used when crushing hard materials, but the number of hammers is not required to be large. When crushing small and soft materials, it is advisable to use lightweight hammers. The number of hammers can be increased to increase the impact frequency of the material, which is more conducive to material crushing. And the alloy hammer adds higher hardness metals such as chromium and molybdenum to the striking surface, resulting in a HRC hardness of over 60. The hammer handle is made of material with good toughness, which is not only wear-resistant but also less prone to fracture.

The alloy hammer head will experience varying degrees of wear after use. Due to low impact conditions, the work hardening effect on the surface of the hammer head will also increase. Hammer wear refers to the gradual detachment of the surface of a metal hammer from the substrate under mechanical force, resulting in changes in the performance of the hammer. When the force of the hammer type alloy hammer head shifts and the wear effect of the hammer head changes, it indicates that the service life of the hammer head is about to end and the hammer head is about to fail. If this situation is found in work, it should be resolved as soon as possible and avoided as much as possible during work.
