MAC
Thermocouple Protection Tubes
|
| Metaullics offers a new, high-performance, advanced ceramic
product especially for use in molten aluminum and zinc applications. Manufactured
by Metaullics, the Metaullics Advanced Ceramic (MAC) thermocouple protection
tubes provide excellent durability, thermal shock resistance, temperature
measurement response, and long life. A true composite between fine-grained
silicon carbide and boron nitride, these protection tubes are extremely
resistant to wetting by molten aluminum and aluminum oxide. Life of three
to six months can be achieved. Superior performance at a reasonable price
provides significant value in comparison with other high performance ceramic
systems such as nitride-bonded silicon carbide, sialon, silicon nitride,
and aluminum titanate.
|  available with nipple, flanged or plain ends. |
