Here’s a brief introduction to copper-zinc alloy target material.
Copper-zinc alloy, also commonly known as brass, is an alloy composed of copper and zinc. The copper-zinc alloy target material is produced through the melting and refining of high-purity copper and zinc. This type of alloy target material boasts high purity, typically reaching above 99.95%, and exhibits excellent density and vibrant color. The zinc content in such alloy targets can reach up to 40%.
The microstructure of brass varies with its zinc content. For brass with a zinc content below 35%, its microstructure at room temperature consists of a single-phase α solid solution, known as α brass. Brass with a zinc content ranging from 36% to 46% consists of both α and β phases at room temperature, called (α+β) brass or duplex brass. When the zinc content exceeds 46% to 50%, the microstructure at room temperature is composed solely of the β phase, termed β brass.
Copper-zinc alloy target materials are widely used in sputtering targets for coating machines due to their dense and smooth film-forming capabilities, as well as strong film adhesion. They are crucial materials in fields such as industrial mold coatings, decorative coatings, large-area coating, thin-film solar cells, data storage, optics, flat-panel displays, and large-scale integrated circuits.
In addition, by adding other alloying elements such as silicon, aluminum, tin, lead, manganese, iron, and nickel to brass, special brass can be obtained to improve specific properties of the alloy. These special brasses have broader application scenarios and meet the diverse needs of various industries.
In summary, copper-zinc alloy target material, with its high purity, good density, and excellent film-forming performance, plays an important role in many industrial fields and has broad application prospects.
