90WNiFe Tungsten alloy block
Description
High melting point: Tungsten has the highest melting point among all pure metals, reaching 3422°C (6191.6°F), which endows tungsten alloy sheets with exceptional resistance to high-temperature environments.
Outstanding mechanical strength: These alloys are extremely hard and durable, often exceeding the hardness of many other metals; this makes these components more durable and wear-resistant.
High thermal conductivity: Tungsten exhibits high thermal conductivity, making it suitable for applications requiring continuous and controlled heating.
Application of tungsten alloy syringe protective covers
