Copper-aluminum eutectic materials can be made into plates with a width of up to 800mm using the liquid-solid casting and rolling process, with thickness ranging from 14mm to 0.5mm. It is convenient for the processing of special-shaped parts, so it has become a new favorite to replace copper parts in applications such as molded case circuit breakers, knife switches, photovoltaic junction boxes, terminal blocks, and charging pile connection bars.
Copper-aluminum eutectic composite bar, electrical accessories, connector
Production equipment such as casting-rolling, hot quenching, cold rolling, cleaning, slitting, stamping of aluminum plates and strips, and key technologies such as aluminum-based crystal combination and recrystallization
Copper-aluminum eutectic plate and strip is a product independently developed by the company on the basis of existing aluminum plate and strip casting and rolling, which is the first of its kind in the world and China. The product adopts a unique solid-liquid casting-rolling composite forming technology. During the transformation of aluminum liquid from liquid phase to solid phase, solid copper plate and strip are synchronously introduced and rolled by casting rolls under high temperature and high pressure, so that the atoms at the interface of the two metals penetrate and crystallize together, forming a unique copper-aluminum eutectic composite plate. Compared with the copper-aluminum composite plates produced by traditional extrusion-drawing method, welding composite method and explosion composite method, it has a subversive upgrade in properties such as peel strength, current carrying capacity, electrical conductivity, tensile strength and shear strength. The product uses aluminum instead of copper, and its performance is better than copper. It can reduce the user's original pure copper application cost by more than 40%. It plays a great role in alleviating the situation of more aluminum and less copper in China, and promoting the national "double carbon" economy and the national strategic reserve of scarce resources.
