ALUMINIUM TESTS
The applying of extremes of temperature and climate in corrosion trials of architectural aluminium include exposure of test pieces at Scott Base and in New Guinea, members of the New Zealand Institute of Metals were told in Christchurch on Wednesday evening.
Corrosion tests were also being carried out in various places in New Zealand, including Christchurch, Mr F. W. Fahy, of the School ot Engineering, University of Canterbury, told members. Mr Fahy said aluminium and its alloys were being used in increasing amounts in the building industry because of its higher resistance to corrosion—a protection given by the tenacious film of oxide that formed naturally on its surface. This film could be thickened electrolytically and could also be used as a decorative coating called anodising. To assess the behaviour of this anodising five atmospheric racks had been set up in Christchurch. They were at Christchurch Airport; next to a fertiliser and chemical manufacturing works; at an industrial site; at a marine site; and on a residential site.
