Target is a material commonly used in the electronic information industry. Despite its wide range of uses, the public does not have a good understanding of this material. Many people are curious about what are the manufacturing methods of target material. How is it categorized? The following article will introduce the manufacturing methods and categorization of target material for use.

The manufacturing method of target material has a few methods

  1, casting method

  The Casting method is a certain proportion of alloy material melting, and then the melted alloy solution is poured into the mold to form ingots. After processing to form the target material. Casting methods usually require melting and casting in a vacuum. Commonly used casting methods include vacuum induction melting, vacuum arc melting, and vacuum electron bombardment melting. The advantage is that the target material produced by low impurity content, and high density, can be mass production; the disadvantage is that when the melting point and density of two or more metals with significant differences in the melting, the use of conventional melting methods is difficult to produce a uniform composition of alloy target material.

  2, powder metallurgy method

  Powder metallurgy is the alloy material according to a certain composition ratio melting, and then the molten alloy solution is cast into an ingot process. The ingot will be damaged, the damaged powder static molding, and then sintered at high temperature to form the target material. The advantage of the target material made by this method is its uniform composition; low defect density and high impurity content. Common powder metallurgy industries are cold pressing, vacuum hot pressing, and hot isostatic pressing.
