Prepainted Color Coated Aluminum Coils And Sheets Prepainted Aluminum Coil
2000 series of alloys are a set of "hard alloys". The aluminum-copper alloys typically contain between 3 to 5% copper, with smaller additions of other elements. The copper provides substantial increases in strength and facilitates precipitation hardening. The introduction of copper to aluminum can also reduce ductility and corrosion resistance. The susceptibility to solidification cracking of aluminum copper alloys is increased; consequently, some of these alloys can be the most challenging aluminum alloys to weld. These alloys include some of the highest strength heat treatable aluminum alloys.
