Description of Cobalt Chromium Tungsten Target (CoCrW Target)

The CoCrW Target is a robust, high-performance alloy designed for sputtering applications, distinguished by its excellent mechanical strength, thermal stability, and remarkable resistance to corrosion and wear. The cobalt component serves as a durable and flexible base, enhancing the alloy’s ductility and ability to withstand high temperatures. Chromium contributes by forming a protective oxide layer, ensuring the material remains resistant to harsh chemical environments and oxidation. Tungsten, known for its high melting point and exceptional hardness, reinforces the alloy’s structural integrity, allowing it to endure extreme thermal and mechanical stresses without degradation.

This combination results in a stable, homogeneous microstructure with fine grains, typically achieved through advanced manufacturing processes like vacuum arc melting or hot isostatic pressing. The alloy boasts a broad melting range, low porosity, and compatible thermal expansion properties, making it ideal for challenging thin film deposition processes. Additionally, its moderate electrical conductivity ensures consistent sputtering performance, while its durable nature guarantees dimensional stability and long-lasting target performance during extended sputtering operations.

Raw Materials – Tungsten

Tungsten (W) is a refractory metal renowned for its extremely high melting point, exceptional mechanical strength, and resistance to thermal and chemical degradation. With an atomic number of 74, tungsten belongs to the transition metal group on the periodic table. It holds the highest melting point of all metals at 3422 °C and a boiling point of approximately 5555 °C, making it perfect for applications that involve extreme temperatures. Tungsten is dense (19.25 g/cm³), hard, and offers excellent thermal and electrical conductivity. Chemically, tungsten is relatively inert, resisting oxidation at room temperature and maintaining stability in a variety of corrosive environments. Its strength and low vapor pressure at high temperatures make it indispensable in aerospace, electronics, and high-performance alloying applications.
