| 2. since the amount of sludge should be much reduced by its use. The 8% copper aluminium alloy is more susceptible to local corrosion than RR5OL so that the aluminium in the sludge will be much reduced by its use. Heads have only been cast in R.R.50L recently. H1. HE The presence of zinc has been tried out without any distinct advantage being noticed. It is possible to cadmium plate the inside of the cast iron water jacket. This protection is being tried out. | ||
