The future development of aluminum alloy in shipbuilding industry

Update time : 2022-10-12 19:31:38

Since 1981, industrial aluminum profiles have been used in the shipbuilding industry for nearly a hundred years. With the development of the aluminum alloy industry, the price of aluminum has dropped sharply in recent years, and there are more and more skilled workers in the aluminum alloy welding industry. The popularization of welding technology has brought about the rapid development of aluminum alloy ships.

Advantages of aluminum alloy boats:

1. Excellent welding performance. Welding has obvious advantages over riveting, because the properties lost due to welding cannot be recovered by re-heat treatment in shipbuilding, while industrial aluminum profiles have good welding crack resistance, and the performance of welded joints after welding is not much different, so it is beneficial to Shipbuilding welding use.

2. Excellent corrosion resistance. When aluminum comes into contact with air, it will form a dense and strong aluminum oxide film on its surface, which can well resist the erosion of various elements in seawater. Coupled with anodization technology, industrial aluminum profiles can maintain a stable form in seawater.

3. Low density and lightness. The density of aluminum is only one-third of that of iron. Under the premise of the same hull size, the industrial aluminum hull brings light weight, which is greatly beneficial to the high speed improvement and fuel economy of the ship, so that it can be used in the same oil. Get a long cruising range.

The application of aluminum alloys in the shipbuilding industry has a history of more than 100 years, especially in recent years, aluminum alloys have been used in various types of ships. The United States, Japan, the United Kingdom and the former Soviet Union have long used aluminum alloy as one of the main materials for ship structures.

Aluminum extrusion profile six places are required during the stretching process

Jul .07.2023

The aluminum extrusion profile must be cooled to below 50 degrees before stretching. If the temperature is too high, stretching will not only burn the human body, the hair belt, but also expose absolute waste products such as bending, twisting, and poor performance before and after aging, because the stress in the aluminum alloy profile can not be completely eliminated.

Curtain wall aluminum profile purchase mainly see where?
