HC Deb 12 February 1980 vol 978 c579W
Mr. W. E. Garrett

asked the Secretary of State for Industry what is the number of aluminium foundry and casting plants in the United Kingdom; and what is the percentage of output relative to the United Kingdom demand for aluminium castings.

Mr. David Mitchell

It is estimated that there are about 500 companies in the United Kingdom producing aluminium castings, and that they have the capacity to meet domestic demand which was probably about 100,000 tonnes in 1979. More precise information is not available.
