Metallic article

Abstract

A metallic article can include a cast metallic body and at least one metallic element. The cast metallic body defines at least one first space. The least one metallic element is received in the cast metallic body and seamless with the cast metallic body. The at least one metallic element is exposed from the at least one first space. A heat conductivity of the cast metallic body is lower than that of the at least one metallic element. The present disclosure further provides a method for manufacturing metallic article.

What is claimed is: 
     
         1 . 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 defining a first space communicating with the first end and a 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.   
     
     
         2 . The metallic article of  claim 1 , wherein the at least one first space comprises two first spaces, the two first spaces are defined at the cast metallic body and correspond to opposite ends of the at least one metallic element, respectively. 
     
     
         3 . The metallic article of  claim 2 , wherein at least one second space depresses from the metallic article to the at least one metallic element, such that the at least one metallic element is exposed from the at least one second space. 
     
     
         4 . The metallic article of  claim 3 , wherein the at least one second space is positioned between the two first spaces. 
     
     
         5 . The metallic article of  claim 1 , wherein one or more metallic elements are one or more metallic tubes or one or more metallic sheets.
