22 Jan Global Casting Tonnages up 10Mt per year compared with 10 years ago
Modern Casting Magazine has recently published their 2016 census of world casting production. The figures show that global production was 104.4Mt, with 91.6Mt being produced by the top 10 producing nations (China 47.2Mt, India 11.35Mt, USA 9.4, Japan 5.2Mt, Germany 5.2Mt, Russia 3.9Mt, Republic of Korea 2.6Mt, Brazil 2.1Mt and Italy 2.1Mt).
Ferrous casting production was down by 1% on 2015, whilst non-ferrous production grew by 5.7%, led by Al alloy castings at 17.9Mt, Cu base 1.87Mt, Zn 1.0Mt and Mg at 0.32Mt. 50 years ago, grey iron alone accounted for over 75% of global output, whereas ductile iron now accounts for around 24% and aluminium 17% (both were at less than 6% in 1966). Grey iron still accounts for over 47% of global output however, and steel has only decreased by a small percentage and still represents over 10% of total global casting output – and of course total production would have been lower 50 years ago. Just 10 years ago, in 2007, global production was reported to 94.9Mt, so there are now 10Mt more castings being produced annually.
Growth in production was 0.4% between 2014-2015 and 0.2% between 2015 and 2-16 according to the reported shipments, whilst the number of metal casting plants reduced by 1.4%, according to Metal Casting, reflecting a continuing trend towards consolidation and greater efficiency. Germany tops the table for plant productivity, at 8.895t/plant annually, with the average globally being 2.25t/plant.
