Abstract： In recent years, the dual-liquid bimetal technology has been widely used in the manufacture of wear-resistant parts, such as hammers, lining plates, impact plates and jaw plates. The forming method, casting method, technical difficulties and application status of double liquid bimetal technology are briefly introduced in this paper. The application of dual-liquid bimetal in a hammer is mature, but the matching degree of solidification temperature in mass production is still slightly defective. The deepening of research and the expansion of materials and processes will promote the continuous break through of dual-liquid bimetal technology, meet the needs of modern production, and refine and perfect the performance control and application range of parts. In addition, this paper also proposes the technical bottleneck and development direction of bimetallic technology that needs to be addressed in the future.
