Advantages of tungsten
Our tungsten and its alloys are used in very special industrial applications that reflect the unique properties of this material. The following sections offer insight into three of these applications:
High rigidity, high modulus of elasticity, and biocompatibility
Fine tungsten wires feature an impressive combination of high rigidity and very good biocompatibility. They can transfer high force without breaking and without permanent deformation thanks to their high rigidity combined with high yield strength. This makes them ideal for use in surgical robots, where extreme precision is needed to control the movement of miniaturized surgical instruments. The excellent surface quality of the wires extends the life of the finished cable, minimizing the risk of complications in medical applications.
Low vapor pressure, good electrical conductivity, and low thermal emissivity
Components made from tungsten and its alloys are often used in high-vacuum systems where maximum purity is required. Heating elements made from tungsten-based materials allow for high current resistance and thus the transfer of high power to achieve high temperatures. The low vapor pressure of tungsten materials prevents the furnace load from being contaminated. Tungsten is especially ideal for use as a shield pack to minimize energy loss, thanks to its low emissivity among other things.
Low sputter rate and excellent corrosion resistance
In ion implantation systems, ion source chambers and beam guidance components are often made from tungsten. These parts must withstand constant ion bombardment and keep their structural integrity over long periods of time, to ensure consistent output and reduce maintenance costs. The low sputter rate and excellent corrosion resistance make tungsten a suitable material in this application area.
