기술
5754 aluminum alloy sheet with moderate strength , 내식성 , weldability and ease of processing forming characteristics such as Al-Mg alloy typical alloys. At abroad, 5754 heat-treated aluminum plates of different states are main material used in in the automotive industry ( 자동차 문 , dies , 씰 ) 및 통조림 산업 .
응용 프로그램
5754 aluminum is widely used in welded structures , 저장 탱크, 압력 용기 , marine structures and offshore facilities , transport tanks and for requiring excellent processing performance, 우수한 내식성, 높은 피로 강도 , weldability and high static strength of the medium occasions.
Aluminum surface
1, the surface does not allow cracks, corrosion spots and traces of nitrate .
2, allow the surface defect site where the depth does not exceed the nominal wall thickness of 8% from the size of the skin , bubbles, surface roughness and local super mechanical damage , but can not exceed the maximum depth of defects 0.5mm, the total area of the defect does not exceed the total area of the plate 5% .
3, allowing supply to the lighting along the longitudinal profile smooth surface .
4, Other requirements: demand-side and supply side to develop their own
