FOSECO NON-FERROUS FOUNDRYMAN HANDBOOK PDF

International SI units are used throughout, but in almost all cases conversions to the more familiar Metric and Imperial units are given. Wherever possible, Casting Alloy Specifications include equivalent specifications for several countries as well as international specifications. Individual chapters cover the casting of all types of non-ferrous metals. For each group of alloys, specifications, and typical applications are described, together with details of melting practice, metal treatment and casting practice. Sand molding materials, including green sand and chemically bonded sands are also included. Recently there have been many major technical developments including new sand binders, the adoption of metal filtration of castings and widespread use of computers for the optimization of feeder design.

Back There are three main types of non ferrous metals: aluminium, magnesium and copper. Aluminium casting is dominated by the automotive industry. Although aluminium castings are more expensive than ferrous castings, there is a continuing market requirement to reduce vehicle weight and to increase fuel efficiency. When aluminium alloys are cast, there are many potential sources of defects which can harm the quality of the casting such as shrinkage defects, gas porosity and oxide inclusions.

Pressure diecasting is the most commonly used casting process for aluminium as well as magnesium alloy castings. Magnesium alloy castings are used for aerospace, automotive and electronic applications. Their main advantage is their light weight.

The melting of copper and copper-based alloys also presents special problems. Molten copper dissolves both oxygen and hydrogen and on solidification, these can cause porosity in the casting.

Foseco supplies products and equipment for each of the non ferrous metal types to prevent casting defects.
