Hinge

The invention relates to a hinge, and belongs to the field of metal materials. The hinge is prepared from the following raw materials in percentage by mass: 0.12-0.2% of Si, 0.1-0.16 of Mn, 0.1-0.14%of Ni, 0.1-0.2% of Mg, 0.3-0.9% of Schiff base, 0.02-0.06% of Tc, 0.04-0.08% of Se and the balance Al and impurities, and prepared through Schiff base preparation, alloy preparation and forming; the specially-added Schiff base containing -OH bond aromatic group extremely easily forms a complex with metal, so that the corrosion of metal is prevented; and the particle size of Schiff base powder is controlled to be submicron order, so that the connection rate between the Schiff base powder and an alloy powder can be increased, the appearance of a tensile fracture presents many dimple structures,and pores in a metal sheet are rounded. 本发明涉及种合页，属于金属材料领域，合页由如下质量百分比的原料制成：Si：0.12-0.2％、Mn：0.1-0.16％、Ni：0.1-0.14％、Mg：0.1-0.2％、席夫碱：0.3-0.9％、Tc：0.02-0.06％、Se：0.04-0.08％、余量为Al和杂质，并经席夫碱配置、合金制备、成型制备而成，特殊添加的席夫碱，含有-OH键芳香族的席夫碱，极易与金属形成络
