Bi-metal Casting Part

Bi-metal Casting Part

Bimetallic composites 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 A128, main parts as below: High –Chromium Square Hammer, High-Chromium Flat Hammer, Ni-Hard Square Plates, Ni-Hand Ox-Head and 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 & plates, cutlery for sugar mill, high-chromium hammer and Bi-metallic hammer tip. The 3rd type is three layer composites based on tungsten carbide and High-chromium cast iron vacuum brazing onto steel backing plate. Such as three layer carbide hammer tips and three layer liner (Carbide+ High-Chromium White Iron + Carbon Steel Plate). The 4th type is strengthen wear parts for Mining and Construction like strengthen blade and teeth based on build-up welding, which mainly include WC flux-cored wire and tungsten carbide particles with strict technical data. Such as build-up welding broken carbide bars, B build-up welding broken carbide blade, build-up welding strengthen teeth and bar is completely covered by broken carbide. The 5th type is strengthen wear parts based on high frequency welding, which high frequency brazing the tungsten carbide on quick wearing position, such as for agricultural tillage point with Welded Tungsten Carbide, chisel plow sweep, tillage tip and knife blade, breaking Hammer welded tungsten carbide and snow shovel blade. The 6th type is cast composites compounded by High-chromium and general cast steel to improve wear resistance and assembly. Pour & solidify a wear resistant material to a structural low alloy or carbon steel box, such as Bi-metallic box, Bi-metallic Rail and plate. The 7th type is cast composites based on tungsten carbide particles enhancing into High-chromium cast iron to improve wear resistance to a great extent. Such as strengthen broken carbide particles and high-chromium cast iron wear plates, and strengthen carbide particles &high-chromium cast iron bars 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. Such as crusher tooth and tooth base.
