Einsatzbeispiele

General use where high strength, medium ductility, and pressure tightness are required, such as pump bodies and liquid-cooled cylinder heads.
These castings have been used typically for components requiring high strength at room and elevated temperatures, but usage is not limited to such applications.
These castings have been used typically for components requiring moderate strength and dimensional stability up to 149°C, but usage is not limited to such applications.
These castings have been used typically for components requiring strength up to 232°C (450°F), but usage is not limited to such applications.
These castings have been used typically for parts requiring moderate strength up to 149°C, but usage is not limited to such applications.
Used typically for parts where strength is not a prime consideration, but usage is not limited to such applications.
