With aluminum and aluminum alloy as the base, the composite materials with a certain thickness of copper and copper alloy strip are continuously compounded on one or both sides by continuous casting semi molten rolling composite method or other methods. The composite interface is metallurgical bonding.
Metallurgical bond
It refers to the combination formed by the diffusion of atoms between the interfaces of two metals.
Cladding metal
Copper and copper alloy which play various functions in copper aluminum composite strip.
Base metal
Aluminum and aluminum alloy which play an auxiliary role in the copper aluminum composite strip.
Continuous casting and semi molten rolling composite method
On the basis of continuous casting technology, the rolling composite method is realized by rolling two materials in semi molten state.
Peel strength
The force required to peel the unit width cladding from the surface of the base course.
Recombination rate
The percentage of metallurgical bonding area of Cu Al Cu clad bimetal strip sheet
the total interface area.
