Per Chenyu Li / hcfire360 July 2021

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

Summus Chromium Flat Hammer

Ni-Puer Square Plates

Ni-Hand bos-caput

Malleus 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.

Strengthen Broken Carbide Particles and High-chromium Cast Iron Wear Plates


The 8th type is strengthen surface by plasma transferred arc(PTA) overlay welding. The overlay thickness is 3-30mm, hardness could be controlled range from 60-70HRC. No surface crack, no weld bead and flat surface finish.
