Mingtai Aluminum leads China's shipbuilding aluminum market trend

Edit:admin Date: 2017-03-16 13:17
Shipbuilding aluminum alloy  has many advantages, can reduce the ship weight, increase the speed, reduce fuel consumption, good corrosion resistance, can increase the service life of the ship; processing good formability, easy cutting, stamping, cold bending, forming and cutting Various forms of processing, welding performance of good elastic modulus is small, the ability to absorb the impact of stress, a greater security; material easy to obtain, recyclable.

Aluminum in the shipbuilding industry has been the application of more than 100 years of history, especially in recent years, aluminum alloys in various types of ships are examples of applications. The United States, Japan, the United Kingdom and the former Soviet Union has long been aluminum alloy ship structure as one of the main materials. At present, Japan has more than 100 companies are building aluminum high-speed boats, passenger ships and fishing boats, the total number of aluminum alloy ship has more than 2,500, the United States using aluminum alloy to build a variety of ships more than 2,000 ships, Nordic, France, Australia And other countries to build aluminum passenger ships, scientific investigation vessels, etc. about 1,000.

Foreign in the composition of the series has reached a higher level in this regard, the choice of alloy has been serialized, the same alloy available for the state there are several varieties, supporting varieties, complete specifications, in particular, a large number of applications to adapt to the characteristics of the ship Profiles and siding, greatly reducing the welding workload while ensuring the quality of the ship construction, foreign countries have now established a relatively complete ship aluminum alloy system and theory, methods, processes and so on. The present study is to study the effect of adding trace elements on the corrosion properties of Al-Mg alloys. For example, Zr alone can significantly improve the strength of AI-Mg-Mn alloy, improve the strength and plasticity of the alloy. The addition of Sc and Zr did not cause a significant decrease in the corrosion resistance of the alloy, but also increased the strength. It is pointed out that the AI-6Mg-Zr-Sc alloy with Sc element added in the simulated seawater has a pitting effect in the A1-6Mg-Zr and AI-6Mg-Zr-Sc alloys, and the mechanical properties have not only improved significantly It exhibits better corrosion resistance than AI-6Mg-Zr alloy.
 Henan Mingtai Aluminum Co., Ltd. is a large-scale aluminum processing companies listed, Mingtai production of marine aluminum plate has passed the China Classification Society and Det Norske Veritas double certification, perennial hot at home and abroad.
