Brazing is becoming an increasingly popular joining method and especially for aluminum and its associated alloys using vacuum brazing techniques. Some key advantages of vacuum aluminum brazing is its flexibility to join materials of varying shape and form and also its possibilities for joining dissimilar materials. Continue reading

The Melt Conditioned Twin Roll Casting (MC-TRC) Process
The melt conditioned twin roll casting process is a relatively new technology which aims to correct some of the disadvantages of the TRC process namely the reduced strength due to coarse grain structures. The proceeding MCAST process provides conditioning in the melt stage which ultimately generates materials with excellent grain size after the rolling process. Continue reading
Hollow Ingot Casting
Hollow ingot casting is a well-established casting technology which is used by many well-known manufacturers the world over to produce lighter good quality ingots for a range of applications. Some key advantages of hollow ingot castings include shortened forging times and subsequent yield increase and obvious savings in materials and finished product weight. Continue reading
Compacted Graphite Iron: Part Two
Compacted graphite iron (CGI) along with lamellar graphite iron and spheroidal graphite iron define the three main classes of cast iron according to morphology.
An important measure for assessing the application of CGI is the machinability levels and through specific studies it was concluded that CGI is much more difficult to machine than standard grey cast irons. Continue reading
