apraksts
5754 aluminum alloy sheet with moderate strength , laba izturība pret koroziju , 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 ( car door , mirst , roņi ) un konservu rūpniecībā .
Lietojumprogrammas
5754 aluminum is widely used in welded structures , uzglabāšanas tvertnes, spiedtvertnes , marine structures and offshore facilities , transport tanks and for requiring excellent processing performance, lieliska izturība pret koroziju, augsta noguruma stiprība , 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 , burbuļi, 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
