Bi-metallic wear plate castings

Chrome White Iron (CWI) is known for its wear resistance but also the brittleness. Low alloy steel has toughness but is easy to wear out.  How about combining CWI's wear resistance and steel's toughness together? It is possible with our bi-metallic castings! In our bi-metallic casting, CWI and steel base are mechanically bonded together in an innovative way to provide extraordinary wear resistance and toughness. Even if a local area of CWI shattered, it would still be locked in place by the base plate structures, to continue providing wear resistance. 

The CWI on our bi-metallic castings reaches over 60 HRC in hardness, while steel base maintaining a good strength and toughness. In ASTM G65 testing - Dry Rubber

Wheel Abrasion Test (Procedure "A"), we saw only 0.13 grams of weight loss on our bi-metallic castings. 

Although CWI reaches a hardness over 60 HRC, with advantage of our strong machining capability, we are able to do machining to hardened CWI to meet our customers' needs.

Because of its excellent resistance to both impact and wear, our bi-metallic castings are widely used in hoppers, chutes, mix boxes and etc. Mines and oil fields often place our bi-metallic castings at bottom of hoppers and mix boxes, to absorb the impact force that other types of bi-metal plates are not able to handle.
