Titanium Sputtering Ti Grade 1 Grade 2 Silver Sputtering Target Titanium Target Sputtering to Coating

Sputtering is a widely used deposition technique for creating thin films and coatings on various substrates. In this process, material from a sputtering target (usually in the form of a metal or alloy) is bombarded with high-energy ions in a vacuum, causing atoms to be ejected and deposit onto a surface. This results in the formation of a thin, uniform coating. For different applications, specific materials like Titanium Grade 2, Titanium Grade 5, and Silver are often used as sputtering targets due to their unique properties.

Below, I will detail the properties, uses, and benefits of these sputtering targets in coating applications.
