Why HUACHEN SKD (skd61) inner wall barrel is better than centrifuge casting bimetallic barrel?


Because limited to the technology,the bimetallic thickness usually will be uneven. And also because of bimetallic layer is made of bimetallic powder, which surface is with bubbles, and sometimes maybe also with cracks. That will affect the wear resistance.

But SKD (skd61) material is made from the material company,which is very strong,and not have the bimetallic problems. So the surface life is more longer than centrifuge casting bimetallic barrel.
