A technology that has been developed systematically in recent years is that
of the manufacturing of sintered products with predetermined properties. I
t has been demonstrated that such products can be manufactured from waste s
uch as aluminium and aluminium-alloy chips. The method consists in the conv
ersion of the chips directly into a finished product. The method has been a
pplied to the production of composite materials, characterised by good stre
ngth properties at room and elevated temperature, as well as for bearing ma
terials. (C) 2000 Elsevier Science B.V. All rights reserved.
