Accumet Materials’ REFRACTOCAST
ceramics are ideal for potting, encapsulating or casting applications where
high temperature resistance is required.
REFRACTOCAST materials exhibit high thermal conductivity, good
dielectric strength and excellent chemical resistance to 3200 ºF.
Applications include potting
electronic components when it is important to remove heat and hold components
in alignment as well as sensor applications, temperature probes, igniters, high
power resistors and accelerometers. In addition,
REFRACTOCAST is used as furnace components, brazing and heat treating fixtures,
molds and tooling.
Accumet’s high temperature
materials are easy to use. After a
simple air dry for 1-2 hours and a low temperature cure at 200 - 500°F, these
materials are ready to use. REFRACTOCAST contains no volatile organic
compounds, are non-flammable and environmentally safe.
• REFRACTOCAST ALS is a
coarse grain aluminum oxide ceramic used for casting relatively large
structures or potting large sections where good thermal conductivity and
strength are needed to temperatures up to 3000 ºF. REFRACTOCAST ALS is strong and offers good
chemical resistance. Applications include producing brazing and heat treating
fixtures, insulation liners, tooling and furnace components.
• REFRACTOCAST ALF consists mostly of fine grain aluminum oxide ideal for
use in potting small sections or casting small parts where fine detail is
required. It exhibits high thermal
conductivity and good dielectric strength to 3000 ºF. Applications include
potting sensors, electrical feed thrus, thermocouples; temperature probes
vacuum components and halogen fixtures.
