Also in Japan, there has been an increasing use of aluminum (!) in construction, since it will generally be melted and re-used after the structure is no longer useful.

- rowanG077 3y agoWhat's the problem with aluminium? I would always build structures out of aluminium if aluminium would be strong enough. It has extreme corrosion resistance, it's cheap, it's easy to handle, you can easily make almost any imaginable shape with it, you can cheaply reuse it, it's very light.

- hef19898 3y agoAluminiums corrosion resistance is mostly myth so.
- more_corn 3y agoAluminum corrosion resistance is caused by a thin film of aluminum oxide which protects the rest of the material.
- scythe 3y agoAluminum's corrosion resistance is decent, but it's particularly weak to alkali, and cement is alkaline. So.
- hef19898 3y agoAnd to salt, and to contact corrosion woth, e.g., steel. Especially the last one is quite often ignored. Even by people at VW and General Dynamics.
- scythe 3y agoAluminum is generally much more expensive than other construction materials, but less obviously, it has practically no fatigue limit, meaning a structure made of aluminum will eventually fail under repeated loads.
