2. Cost of foams

This is undoubtedly the decisive factor in the industrial development of these products. At present, the cost of metal foams is highly variable, depending on the type of foam, its manufacturing process and technological maturity, as well as the quantities ordered. Some manufacturers position themselves on raw or semi-finished products (panels, foam slices, etc.), while others propose the design of a functional solution integrating the use of metal foam, thus offering a finished part. Finally, product distributors generally market metal foams in the form of relatively small components.

Of course, prices vary considerably depending on the distribution channel.

It is also particularly difficult to compare the costs of different products, as the approach varies according to the function sought for metal foam. For example, cost can be classified...
