CAST IRON MEMBER FOR INSERTING, INSERTED PRODUCT USING SAME AND METHOD OF MANUFACTURING CAST IRON MEMBER FOR INSERTING

摘要

PROBLEM TO BE SOLVED: To provide a cast iron member for inserting excellent in the packing property of an aluminum material and the adhesive strength with the aluminum material when a die-casting is performed, an inserted product using this and a manufacturing method of the cast iron member for inserting.;SOLUTION: As coating material, a suspension prepared by mixing 20-45 mass% solica sand having 0.05-0.5 mm average drain diameter, 10-30 mass% silica flower having ≤0.1 mm average grain diameter, 2-10 mass% binder and 30-60 mass% water is used. The cast iron member for inserting having the inserting surface of 65-260 μm maximum height Ry of the surface roughness and 0.6-1.5 mm average interval Sm between the recessing part and the projecting part and more desirably, 75-250 μm Ry and 0.7-1.4 mm Sm is obtained. The aluminum material is cast on the outer periphery of this cast iron member by die casting to obtain the inserted product.;COPYRIGHT: (C)2001,JPO
