Product Description

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 aluminum strip need to be with high mechanical strength and uniform microstructure and deep drawing property. To make this 3004 O temper 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.  aluminum for lamp cap have good deep drawing quality, enough strength, good formability.
