Cast iron alloy for cylinder heads

摘要

A lamellar graphite cast iron alloy is described which, as additives, has 2.80% by weight-3.60% by weight carbon (C), 1.00% by weight-1.70% by weight silicon (Si), 0.10% by weight-1.20% by weight manganese (Mn), 0.03% by weight-0.15% by weight sulphur (S), 0.05% by weight-0.30% by weight chromium (Cr), 0.05% by weight-0.30% by weight molybdenum (Mo), 0.05% by weight-0.20% by weight tin (Sn) and the usual impurities, and also described is a cylinder head which can be obtained therefrom.
