The name of George Frederick Muntz (1794–1857), English political reformer and metallurgist, used (now always in Muntz metal) to designate a type of brass he patented (Brit. Pat. 6325 (1832), 11,410 (1846)) that contains about 55–64 per cent of copper (often with 1 per cent or more of lead), can be readily hot-worked, and is used esp. in shipbuilding.
