High chrome alloy hammer head Double liquid composite, as its name implies, is to directly cast a variety of metal liquid into one forming, which makes the hammer face high hardness, the hammer handle strong toughness, and solves the problem that the forging hammer head on the sand making equipment does not have to be hit.  In addition, by analyzing the materials sent by the manager of the process, it is found that the materials have certain corrosion, so the content of inert metal in the hammer head is adjusted to improve the corrosion resistance of the hammer head of the sand making machine, and further improve the service life of the hammer head.
