Abstract

The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a preparation method of an aluminum alloy three-layer composite material for brazing. , casting, sawing, milling and surface treatment of the two, welding assembly, heating, hot rough rolling, hot finishing, cold rolling, tension leveling and cleaning, finished annealing and slitting packaging, through component optimization design, can improve The strength of the composite material and the sag resistance after high temperature brazing, while ensuring the balance of mechanical properties and corrosion properties, can well meet the brazing requirements of controllable gas shielded welding; the brazing material and the matrix ingot are combined at the same time. The two-stage heating method of homogenization heat treatment and hot rolling heating can greatly improve production efficiency while reducing energy consumption and meet product performance requirements.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a preparation method of an aluminum alloy three-layer composite material for brazing, in particular to a preparation method of an aluminum alloy three-layer composite material for brazing with excellent comprehensive performance. Background technique [0002] Common aluminum alloy composite materials for brazing are essentially metal layered composite structures, which can be divided into brazing layer, matrix layer and sacrificial anode protection layer according to the role of different material layers. Among them, the brazing layer is made of 4-series Al-Si alloy with low melting point, the base layer is generally made of 3-series Al-Mn alloy with a higher melting point than 4-series, and the sacrificial anode protective layer is made of 7-series Al-Zn- Mg alloy. [0003] According to the different brazing requirements of the part structure, the aluminum al...
