3004-O aluminum alloy strip for lamp cap
3105 aluminum sheet for screw cap
3105 aluminum sheet for screw 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 aluminum 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.
Compare with 8011 closure sheet, 3105 aluminum sheet has enough strength, so it is stronger enough to bear the gas pressure, so it is widely used for making screw cap for gas liquid bottle, such as soda water and carbonated wine.
