The invention relates to the water heating equipment field, in particular to a cold extrusion forming technique of an aluminium alloy water heating part and the water heating part product. The invention solves the problems that the existing product which takes the cast iron as the raw material is rough, has poor mechanical performance, low yield strength, and comparatively large brittleness, is easy to be broken during the construction installation and cracked during chilliness, and is not easy to resist the chilliness; furthermore, the product which takes the copper material as the raw material has high price, low mechanical performance and is not easy to resist the chilliness, and the cold extrusion technique of the aluminium alloy material can not be well formed; the detailed method of the invention can be seen in a manual; the product which is produced by the invention has the advantages of excellent mechanical performance, high hardness and tensile strength, high yield strength beyond comparison, compara
