3004-O aluminum alloy strip for aluminum lamp base cap

To make aluminum lamp cap, first stamping and then tapping into spiral shape, thinner materials and to withstand the pressure. Therefore, the 3004 lamp cap 3004-O aluminum alloy strip need to be with high mechanical strength and uniform microstructure and deep drawing property. Currently signi aluminum use the flat ingot hot rolling for producing blank holder with 3004-O aluminum alloy strip. To make this 3004 O aluminum alloy strip, we have to control the composition of the material and cast rolling process, the high temperature uniformity of annealing and final annealing process, it have good deep drawing quality, enough strength, good formability.
