Aluminum Foaming For Lighter Structure

Aluminum foaming for light weight construction has become an attractive research field both from the scientific viewpoint and the prospect of industrial applications. Various methods for making such foams are available. Some techniques start from specially prepared molten metals with adjusted viscosities. Such melts can be foamed by injecting gases or by adding gas-releasing blowing agents which decompose in-situ, causing the formation of bubbles. A further way is to start from solid precursors containing a blowing agent. Alternatively, casting routes can be used to make such precursors. The properties of aluminum foams promise a variety of applications in vehicle design ranging from light-weight construction, impact energy absorption to various types of acoustic damping and thermal insulation. Aluminum Foaming is not implemented in India. In these seminar a over view of various term like concept, process, properties, advantages, disadvantages and practical applications of it are explained.
