Abstract
A method for manufacturing a heat transfer surface is disclosed wherein the surface of powder or string-shaped copper core material is coated with a coating material of a nickel compound or silver so as to form a coat treatment material which is deposited on a substrate. The coating material has a lower fusing point than the core material, and the coat treatment material is heated to a temperature between the fusing points of the core material and the coating material such that only the coating material is caused to fuse to the substrate so as to form a porous heat transfer material which exhibits improved bending strength.
