In heavy industrial fields including mining, cement production, metallurgy, and bulk material transportation, equipment wear and impact damage are the most common causes of frequent downtime, high maintenance costs, and reduced production efficiency. Traditional single‑metal wear parts such as ordinary cast iron, manganese steel, and low‑alloy steel can no longer meet the demands of high‑intensity, long‑cycle, and high‑abrasion working conditions. In recent years, bimetallic composite wear‑resistant materials have gradually become the mainstream solution for global industrial equipment protection due to their dual‑performance advantages that single metals cannot match.

Bimetallic composite wear‑resistant material is a new‑type composite metal material formed through advanced vacuum welding, laser additive manufacturing, and composite casting technology. It consists of two structurally integrated metal layers: a high‑toughness carbon steel base layer and a high‑hardness high‑chromium alloy wear‑resistant layer. The carbon steel base provides excellent overall toughness, welding performance, and structural stability, while the surface alloy layer delivers ultra‑high hardness and strong anti‑abrasion capability. The two layers achieve perfect metallurgical bonding without delamination, peeling, or cracking during long‑term operation.

ATW’s self‑developed bimetallic wear‑resistant materials reach a maximum hardness of HRC ≥ 65, with uniform internal carbide distribution and stable metallographic structure. Different from traditional surfacing and ordinary composite materials, our products feature smooth surface without pores and cracks, effectively resisting particle scouring, abrasive wear, and strong mechanical impact. This composite structure perfectly solves the industry’s long‑standing technical contradiction that “high hardness leads to brittleness, and high toughness leads to poor wear resistance”.

At present, bimetallic composite wear parts have replaced traditional wear‑resistant products in most heavy‑duty industries. They greatly extend equipment service life, reduce manual maintenance frequency, and help enterprises cut comprehensive operating costs. As industrial upgrading accelerates globally, high‑performance bimetallic composite materials will become the standard configuration for high‑end industrial equipment protection.
