OMEGATITE 650 is uniquely
qualified for non-ferrous molten
metal applications and high wear
or high impact environments up
to 1250°C (2282°F).
OMEGATITE 650 is non-wetting
for most non-ferrous metals. It is
gas tight, chemically inert,
resistant to corrosion and
metal attack, and features high
strength, hardness, and thermal
shock resistance.
OMEGATITE 650 thermocouple
sheaths are used extensively for
continuous measurements in
nonferrous metals. In molten
aluminum, OMEGATITE 650 is
thermally shock resistant, nonwetting, does not contaminate
the melt, provides continuous,
reliable temperature
measurement, and is resistant to
degradation even in aggressive
aluminum lithium alloys.

OMEGATITE®650 is the ceramic
sheath which is an alloy of silicon
nitride and aluminum oxide. This
superior refractory material has the
combined properties of silicon
nitride (high strength, hardness,
fracture toughness, and low thermal
expansion) and aluminum oxide
(corrosion resistance, chemically
inert, high temperature capabilities,
and oxidation resistance). Not
recommended for caustic solutions
and hydrofluoric acid.
Most refractory products can be
used only in high temperature
applications where one or two of the
following properties are required:
thermal shock resistant, mechanical
strength, corrosion resistance,
abrasion resistance or electrical
insulation. OMEGATITE 650
combines all these properties in one
refractory material. Preheating of
the process is not necessary.
Type K or N thermocouple
enclosed in a special
ceramic protection tube.
Standard construction
includes cast iron NEP-TX
connection head and
11⁄4 NPT fitting.
Uses 14 AWG conductors
with two hole round
ceramic insulators.
