Target material is a commonly used material in the electronic information industry. Although it has a wide range of uses, the public's understanding of this material is not profound. Many people are curious about the manufacturing method of target materials? How is it classified? The following editor will introduce the manufacturing methods and classification of titanium targets.

There are several methods for manufacturing target materials

1. Casting method

The casting method involves melting a certain proportion of alloy material, and then pouring the melted alloy solution into the mold to form an ingot. Forming the target material after processing. The casting method usually requires melting and casting in a vacuum. Common casting methods include Vacuum induction melting, vacuum arc melting and vacuum electron bombardment melting. Its advantages are low impurity content and high density of the produced target material, which can be produced on a large scale; The disadvantage is that when two or more metals with significant differences in melting point and density melt, it is difficult to produce alloy targets with uniform composition using conventional melting methods.

2. Powder metallurgy method

Powder metallurgy is the process of melting alloy materials according to a certain composition ratio, and then casting the melted alloy solution into ingots. Damage the steel ingot, statically shape the damaged powder, and then sinter it at high temperature to form the target material. The advantage of using this method to manufacture targets is that their composition is uniform; Low defect density and high impurity content. Cold pressing, vacuum hot pressing and Hot isostatic pressing are common in powder metallurgy industry.
