Metallic article and method for manufacturing metallic article

A method of manufacturing metallic article comprising:

• providing a mould, a position tool, and at least one metallic element, the position tool comprising a first position member and a second position member detachably coupled to the first position member;
• positioning the first position member and the at least one metallic element coupled to the first position member into the mould,
• coupling the second position member with the first position member, such that the at least one metallic element positioned between the first position member and the second position member,
• injecting melt metal into the mould, a heat conductivity of the melt metal being lower than a heat conductivity of the at least one metallic element,
• cooling the mould, and taking the position tool and a metallic article out of the mould, the at least one metallic element inserted in the metallic article,
• taking the metallic article out of the position tool.

A metallic article comprising:

• one or more metallic elements made of a first material, each of the one or more metallic elements having a first end and a second end;
• and
• a cast metallic body made of a second material, the cast metallic body surrounding the one or more metallic elements, with the cast metallic body including a defined first space communicating with the first end and a defined second space communicating with the second end of each of the one or more metallic elements;
• wherein, the second material has a heat conductivity lower than the first material.
