Meli za baharini huingizwa kwenye maji ya bahari kwa muda mrefu. Kutokana na mazingira maalum, mahitaji ya vifaa vya sahani za meli na sehemu za karatasi za chuma ni za juu sana. Inahitajika kuwa na upinzani bora wa kutu, nguvu ya juu, utendaji bora wa kulehemu na utendaji mzuri wa kutengeneza. 5083 sahani ya alumini na 5086 aluminum plate can be used in the field of marine ships and have good application effects.
5086 na 5083 sahani ya alumini ya daraja la baharini in common
5083 karatasi ya alumini na 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, kama vile meli, automobiles and aircraft plate weldable parts. As well as pressure vessels, refrigeration equipment, television towers, installation and detection equipment, vifaa vya usafiri, na kadhalika., which require strict fire protection.
Tofauti kati ya 5083 karatasi ya alumini na 5086 karatasi ya alumini
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: Na: ≤ 0.4 Cu: ≤ 0.1 Mg: 4.0 - 4.9 Zn: 0.25 Mhe: 0.40 - 1.0 Ya: ≤ 0.15 Cr: 0.05 - 0.25 Fe: 0.4
5086 aluminum plate content of each chemical composition: Mg: 3.5 ~ 4.5 Zn: ≤ 0.25 Mhe: 0.20 ~ 0.7 Ya: ≤ 0.15 Cr: 0.05 ~ 0.25 Fe: 0.000 ~ 0.500
5083 mali ya mitambo: nguvu ya mkazo σb (MPa): 110-136 elongation δ10 (%): ≥ 20 annealing temperature: 415 ℃ yield strength σs (MPa) ≥ 110
5086 mali ya mitambo: nguvu ya mkazo σb (MPa): ≥ 240 nguvu ya mavuno ya masharti σ0.2 (MPa): ≥ 95 elongation δ10 (%): ≥ 10 elongation δ5 (%): ≥ 12
