Abstract

The application discloses a method for preparing a through-type composite strip embedded with silver copper. The method comprises the steps of: extruding silver and copper ingots into profiled strips according to a design shape, respectively cleaning the surfaces of the profiled silver strip and the purchased profiled copper strip, removing a greasy dirt, an impurity and oxide on the surface; mutually embedding the silver strip and the copper strip into a whole; reinforcing and welding two heads to prepare a pre-composite material; continuously rolling and hot rolling to form a silver copper composite material from the pre-composite material under a complete-atmosphere protection state; dragging and receiving materials by a receiving machine, and then annealing in a diffusion manner, rolling and cutting to obtain the product. The method disclosed by the application is high in bonding strength, low in demand on manufacturing device, easy to process, long in length of strip, and convenient to automatically process, and manufacturing on a large scale can be carried out, thus, the cost is greatly reduced.

Description

Technical field

[0001] The invention relates to a material processing method, in particular to a preparation method of a silver-copper-inlaid penetrating composite strip. Background technique

[0002] Precious metal (gold and silver, etc.) composite materials, electrical switches, thermostats, fuses, micro-motor brushes and other new contact materials for instruments and meters. It mainly undertakes the functions of making and breaking current and fuse. It has good resistance Electric grinding, conductivity and fusing performance are widely used in low-voltage electrical appliances and fuses. It has the advantages of good overall performance and low silver consumption, effectively saving the consumption of precious metal resources.

[0003] As a substitute for pure silver, silver-copper through-type composite material maintains the fast fusing effect of pure silver material, and is currently an ideal substitute for pure silver fusing.

[0004] At present, the preparation methods for...
