Wire made from refractory metals, such as tungsten, tantalum, molybdenum, and titanium, offer unique properties that make them well-suited for a wide range of high-temperature applications. These metals can withstand extreme temperatures and harsh environments, making them ideal for use in aerospace, nuclear, and other high-tech industries.
Refractory wire made of the following alloys is available in the company «Special Materials»:
- AERIS 1750 (W 99.9%),
- AERIS 308 (Ta 99.99%),
- AERIS 1710 (Mo),
- AERIS 1715 (Ti).
One popular wire material used in these industries is AERIS 1750, which is made of 99.9% pure tungsten. This material is known for its high melting point, excellent thermal conductivity, and good electrical conductivity. It is commonly used in the manufacture of heating elements, electrical contacts, and other high-temperature applications.
AERIS 308 is a tantalum wire with a purity of 99.99%. This material is highly resistant to corrosion and erosion, making it ideal for use in chemical processing, electronics, and nuclear applications. It is also used in the production of medical devices, as it is non-toxic and biocompatible.
Molybdenum wire, such as AERIS 1710, is known for its high strength, excellent thermal conductivity, and good electrical conductivity. It is often used in the production of furnace components, heating elements, and electrical contacts.
Titanium wire, such as AERIS 1715, has a low density and excellent corrosion resistance. It is commonly used in the manufacture of medical devices, such as implants and instruments, as well as in the aerospace and chemical industries.
