Aluminum plate for ship chimney
What is the Ship Chimney
As the exhaust device of the ships, the chimney includes a set of exhaust pipes or the like supported on the hull of the ship. In passenger ships and especially on large cruise ships, it is important to minimize The harmful effects of exhaust gas on the outer deck. Exhaust pipes usually extend significantly above the actual deck superstructure and the highest deck.

5083 aluminum plate: It is often used for the ship chimney. It has good strength, corrosion resistance, machinability and good anodizing effect. Excellent corrosion resistance makes aluminum plate 5083 manufacture different parts of ships like hull, deck and chimney.
Aluminum alloy 5052 has high strength, high fatigue strength, high plasticity and corrosion resistance, and good plasticity when hardened by semi-cold work. Haomei aluminum plate has no peeling, air bubbles, surface roughness and local mechanical damage.
5A03 aluminum sheet is used for welding structures and parts of ships such as light partition walls, enclosure walls, radiators, pipelines and chimney shells. 5A03 has a pitting corrosion depth of less than 0.3 mm after 8 years of exposure, showing good corrosion resistance.
