Ang mga barkong pandagat ay nalulubog sa tubig dagat sa mahabang panahon. Dahil sa espesyal na kapaligiran, ang mga kinakailangan para sa mga materyales ng mga plato ng barko at mga bahagi ng sheet metal ay napakataas. Ito ay kinakailangan upang magkaroon ng mahusay na kaagnasan paglaban, mataas na lakas, mahusay na pagganap ng hinang at magandang pagbuo ng pagganap. 5083 aluminyo plate at 5086 aluminum plate can be used in the field of marine ships and have good application effects.
5086 at 5083 marine grade aluminyo plate in common
5083 aluminyo sheet at 5086 aluminum sheet are both 5 series AL-Mg alloys, which are widely used as rust-proof aluminum. Both are used in applications where high corrosion resistance, good weldability and medium strength are required, tulad ng mga ships, automobiles and aircraft plate weldable parts. As well as pressure vessels, refrigeration equipment, mga tore ng telebisyon, installation and detection equipment, kagamitan sa transportasyon, atbp., which require strict fire protection.
Ang pagkakaiba sa pagitan ng 5083 aluminyo sheet at 5086 aluminyo sheet
The main difference between these two grades of aluminum sheet is the different chemical composition content and the difference in mechanical properties.
5083 aluminum plate chemical composition content: Si: ≤ 0.4 Cu: ≤ 0.1 Mg: 4.0 - 4.9 Zn: 0.25 Mn: 0.40 - 1.0 Ti: ≤ 0.15 Cr: 0.05 - 0.25 Paa: 0.4
5086 aluminum plate content of each chemical composition: Mg: 3.5 ~ 4.5 Zn: ≤ 0.25 Mn: 0.20 ~ 0.7 Ti: ≤ 0.15 Cr: 0.05 ~ 0.25 Paa: 0.000 ~ 0.500
5083 mekanikal na mga katangian: makunat lakas σb (MPa): 110-136 elongation δ10 (%): ≥ 20 annealing temperature: 415 ℃ yield strength σs (MPa) ≥ 110
5086 mekanikal na mga katangian: makunat lakas σb (MPa): ≥ 240 Kondisyonal na Lakas ng Yield σ0.2 (MPa): ≥ 95 elongation δ10 (%): ≥ 10 elongation δ5 (%): ≥ 12
