CuZnNiAl alloy target

What is CuZnNiAl alloy target?

Copper-zinc-nickel-aluminum alloy target materials are alloy materials composed of elements such as copper (Cu), zinc (Zn), nickel (Ni), and aluminum (Al). Copper-zinc-nickel-aluminum alloy target materials with its high purity, good electrical conductivity, corrosion resistance and chemical inertness, customizability, and excellent sputtering performance. They have a wide range of applications in fields such as electronics, semiconductors, and optics, and can be used for preparing various thin film coatings, plating, PVD (Physical Vapor Deposition) preparation, and surface coatings.

What are the characteristics of Copper – Zinc – Nickel – Aluminum pvd coating materials?

1. CuZnNiAl sputtering target with High purity: copper-zinc-nickel-aluminum alloy targets usually have high purity, ensuring high-quality atomic deposition during sputtering. The high purity target can reduce the influence of impurities on the properties of the film, and improve the conductivity, corrosion resistance and chemical stability of the film.
   2. Cu alloy targets with Good electrical conductivity: Because copper, aluminum and other elements are good conductors, copper, zinc, nickel and aluminum alloy targets also have excellent electrical conductivity. This makes it widely used in the preparation of electronic film, conductive coating and so on.
   3. Copper zinc nickel aluminum sputtering target with corrosion resistance and chemical inertia: The addition of zinc and nickel can improve the corrosion resistance and chemical inertia of the alloy. This enables copper-zinc-nickel-aluminum alloy targets to maintain stable performance in harsh environments and extend service life.
   4. metal alloy CuZnNiAl thin film coating materials customizability: The shape, size and surface state of the copper, zinc, nickel and aluminum alloy target can be customized according to customer needs. This flexibility allows it to meet the specific requirements of targets in different application fields.
   5. CuZnNiAl magnetron sputtering target Excellent mechanical properties: alloy targets usually have high hardness and strength, making it possible to maintain the stability and durability of the target during sputtering.                                                                                                                                                             

   What are the production processes of copper, zinc, nickel and aluminum (CuZnNiAl) alloy targets?

   I.prepare raw materials

   1.prepare raw materials: Material selection: According to the composition ratio of the required target, high-purity copper, zinc, nickel, aluminum and other metals are selected as raw materials. 

   2.Pretreatment: pretreatment steps such as cleaning and drying of raw materials are carried out to remove impurities and moisture from the surface to ensure the quality of subsequent smelting and processing.

   II.Second, smelting:
   Melting: The pre-treated raw materials are put into the melting furnace in accordance with a certain proportion for high temperature melting. Furnace temperature and melting time need to be controlled in the melting process to ensure uniform alloy composition.

   1. Casting and forming 1. Casting: The melted alloy melt is poured into the pre-prepared mold for cooling and solidification. The shape and size of the mold should be customized according to the shape and size of the desired target.2. Demoulding and primary processing: waiting for alloy solidification

    III.Heat treatment and grain control

   1. Heat treatment: Heat treatment of the target after initial processing, such as annealing, quenching, etc., to improve its internal structure and properties. It is necessary to control the heating temperature, holding time and cooling method during the heat treatment process.

   IV. Finishing and surface treatment

   1. Finishing: Further finishing of the target after heat treatment, such as turning, milling, grinding, etc., to achieve the required size and shape accuracy.
   V. Surface treatment: the surface of the target is polished, cleaned and other treatment to remove surface oxides and impurities, improve the surface finish and sputtering efficiency.

   VI. Quality inspection and packaging

   1. Quality inspection: Quality inspection of the processed CuZnNiAl sputtering target material, including size, purity, structure, etc., to ensure that the product meets the specified standards.
   2. Packaging: The qualified CuZnNiAl sputtering target material is vacuum-packed to prevent it from reacting with oxygen and moisture in the environment and maintain its quality and performance.   

   The production of copper – zinc – nickel – aluminum alloy sputtering target  demands sputtering target manufacturers meticulous crafting by professional production technicail team. They are well – versed in the precise weighing of copper, zinc, nickel, and aluminum to ensure the correct alloy composition.  During the magnetron sputtering target melting process in the high – temperature furnace, they carefully control the temperature, atmosphere, and stirring conditions to achieve a homogeneous alloy sputtering targets.
