Abstract : Abstract - Copper alloy C19210 have excellent corrosion resistance, heat resistance, and conductivity, and is used for precision electronic parts such as lead frame materials. Conventionally, copper alloy strips are manufactured by repeating heat treatment and cold rolling, and have a problem that it is multi-process and production cost is expensive. On the other hand, twin roll casting can improve the above problems because strips are made directly from molten metals. In this study, twin roll strip casting of copper alloy C19210 using commercial scale machine was operated. The aims of this study is to investigate the possibility of strip casting for copper alloy. The effect of the side dam and release agent was researched. The effect of rolls speed on the strip surface condition was researched. The improved side dam prevented molten metal leakage. The release agent prevented sticking of the manufactured strip to the roll surface. Keywords - Twin Roll Strip Casting, Copper Alloy C19210, Castability, Surface Condition, Release Agent
