Compacted Graphite Iron (CGI) or Vermicular Graphite Irons utilise a modified form of the graphite nodules to produce a material which allows higher tensile strength than grey iron but retains the ability to dissipate heat and damp vibration.
Vanguard has been developing the new material for twelve months and has recently secured an order for several tonnes of iron in batches of 400Kg. Shown above are typical components produced in CGI, details of the chemical composition can be seen in the technical services and specifications area of the website

New material available from Vanguard Foundry Ltd.
Très intéressant…
Vanguard Foundry est devenue une référence pour la fabrication des corps de turbos et turbocollecteurs. Ils ont aussi travaillé au développement de pièces d’échappement en acier.
Ce sont eux qui ont repris de nombreuses fabrications lors de la chute de CF2M.
