An important sputtering material, widely applied in fields such as semiconductors, optics, and magnetic materials due to its excellent physical and chemical performance.

1. Characteristics

1) High Purity and high density

The purity of Ni target is usually ≥99.9% (4 N grade) and partially reaches 99.995% (4 N 5), ensuring high quality of thin film deposition.

・High density (>99%) and uniform crystal grains (average grain size <20 μm) are advantageous for uniformity and stability of    sputter deposition.

2) Excellent electrical and thermal conductivity

・The electrical conductivity is about 14.3 x 10 x 10 x S/m, which is suitable for the production of conductive thin films in the electronics field.

・Thermal conductivity of 90-100 W/(m・K) helps heat dissipation during sputtering and prevents overheating of the target.

3) Good corrosion resistance and anti-oxidation properties

・The target does not easily react with air, acid, or alkali at room temperature, and is highly resistant to chemical corrosion.

4) Ferromagnetism and magnetic stability

・Ni is ferromagnetic and has a Curie temperature of about 360°C, making it suitable for magnetic storage device, sensors,

and other applications.

5) Excellent processing performance

・It can be processed into various shapes such as flat targets, rotating targets, and odd-shaped targets, making it suitable

for various types of film deposition.
