The multi metal binding composite laminate (hereinafter referred to as "composite metal plate - CMP") of Beijing Langqiao Materials Technology Co., Ltd. (LQ) refers to the metal plate that uses a specific process to attach one layer of metal to the surface of another layer of same or different metal, to form a two-layer or multi-layer composite structure. The product is characterized by the high bonding strength between layers. The metal thickness of each layer can be from 50 microns to several millimeters. In addition to the plane surface, the metal layer bonding of irregular 3D surface can also be obtained.
