Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cylinder for an injection-molding machine for light alloy of which the base material secures heat-resistance and high temperature strength and of which the manufacturing cost is lower than that of a conventional cylinder. SOLUTION: In the cylinder for the injection-molding machine for light alloy in which a coating layer made of erosion-resistant material is deposited on the inner surface of the hollow cylindrical base material for the cylinder, the base material for cylinder is formed by joining front cylinder base material disposed at the injection outlet side with back cylinder base material disposed behind the front cylinder base material in the longitudinal direction. The front cylinder base material is made of a nickel-based heat-resistant alloy and the back cylinder base material is made of an iron-based material. COPYRIGHT: (C)2004,JPO
