If you have any demand of Bi-metallic Parts (Bi-metal Parts), please feel free to contact us by email: sales@nbinvestmentcasting.com.
 
Bi-metals are one of our key products. We are able to provide wear-resistant bi-metals with different process:
The 1st type is casting, main material for casting under Wear-resistant White Cast Iron Standard ASTM A532 and High Manganese Steel Standard ASTM A12, main parts as below:


High –Chromium Square Hammer

High-Chromium Flat Hammer

Ni-Hard Square Plates

Ni-Hand Ox-Head

Hammer Shank

The 2nd type is the bimetallic composites based on High-chromium cast iron vacuum brazing onto steel backing plate. The welding strength is 320Mpa and the hardness of High-chromium cast iron is 63HRC. The bimetallic composites include many product categories such as chocky bars and blocks, wear buttons, wear bars and blocks and wear plates.
