Abstract
There is provided a melt supply pipe for aluminum die casting which is strong to mechanical impact and is excellent in the melting loss resistance to a molten aluminum alloy and which has a significantly extended life. The melt supply pipe for connecting a melting furnace and a plunger sleeve of a die casting machine, includes an inner ceramic pipe and an outer steel pipe fitted to the inner pipe, wherein a Ni alloy layer is formed over the inner circumferential surface of the outer steel pipe, and TiC particles are bonded to the surface of the Ni alloy layer.
