WARNING – MATERIAL SPECIFIC FACTS
TITANIUM Ti6AI4V
C.A.T White Bread (WB) Titanium 5.56mm suppressors are limited to barrel lengths of 10″ or longer. Note
that barrel length restrictions are guidelines and users should ensure proper alignment of the suppressor
as well as stability of the projectile exiting their barrel before use. Full Auto or High Rates of Fire (HRF)
(greater than 30 rounds per minute) are discouraged, unless in life threatening self-defense situations, as
the WB Titanium is a lightweight, high performance suppressor dedicated to Low Rates of Fire (LRF).
Ti6AI4V can maintain its mechanical properties up to approximately 752°F (400°C), and as high as 932°F
(500°C), though with heavily reduced mechanical performance. Once the operating temperature
threshold exceeds 800°F (427°C), CAT recommends a cooling down below operating temperature.
Ti6AI4V has inherent material properties which give the material a lower heat conductivity rating, and the
suppressor is susceptible to particle erosion and softening past operating temperature. If the user notices
discoloration on the exterior discontinue use and allow it to cool down. Do not dip the suppressor in
water in an attempt to cool it down.
C.A.T recommends WB Ti6AI4V users invest in an infrared thermometer and create their own platform
specific firing schedule, based on ammunition and barrel length. It is recommended to create a firing
schedule by shooting five round groups, with one second intervals between rounds, then testing the
temperature of the suppressor up to the operating temperature. The user should record the cool down
time until the suppressor returns to 150°F (65°C). This would become the baseline firing schedule based
on the user’s platform and ammunition type.
C.A.T WB Titanium has a dedicated “waffle” style erosion interface at the end of the blast chamber. This is
a sacrificial erosion wall, and users should not be concerned if they are seeing wear, this is designed to
support the erosion caused by unburnt particulates (especially in short barrel platforms) and is designed to
protect other internal areas inside of the suppressor.
Excessive white sparking may be noticed upon first use, this is due to microscopic Titanium dust from the
Additive Manufacturing process. Over the course of use this white sparking will subside but will never fully
disappear, particularly on short barrel platforms. Titanium white sparking is separate from flash and cannot
be controlled by a flash hider or other methods, as it is a byproduct of Titanium being classed as a
reactive metal. If Titanium induced white sparking is an undesirable factor in the suppressor’s application,
C.A.T recommends the use of our Inconel 718 model offerings, as Inconel 718 doesn’t spark.
INCONEL 718
C.A.T White Bread (WB) Inconel 718 5.56mm suppressors are limited to barrel lengths of 5.5″ or longer.
Note that barrel length restrictions are guidelines and users should ensure proper alignment of the
suppressor as well as stability of the projectile exiting their barrel before use. This model is a “duty”
focused suppressor, able to support Full Auto or High Rates of Fire (HRF). IN718, a nickel-chromium alloy,
has excellent high- temperature properties, making it suitable for use in combat environments. IN718’s
typical operating temperature is approximately 1292°F (700°C), and can tolerate temperatures up to
1800°F (982°C), though prolonged exposure is not recommended. Once the operating temperature
threshold is exceeded, CAT recommends a cooling down below operating temperature. The suppressor
is susceptible to particle erosion and softening past operating temperature. If the user notices
discoloration on the exterior discontinue use and allow it to cool down. Do not dip the suppressor in
water in an attempt to cool it down.
C.A.T recommends WB IN718 users invest in an infrared thermometer and create their own platform
specific firing schedule, based on ammunition and barrel length. It is recommended to create a firing
schedule by shooting five round groups, with one second intervals between rounds, then testing the
temperature of the suppressor up to the operating temperature. At the operating temperature, the user
should record the amount of time until the suppressor returns to 150°F (65°C). This would become the
baseline firing schedule based on the user’s platform and ammunition type.
C.A.T WB Inconel 718 has a dedicated “waffle” style erosion interface at the end of the blast chamber.
This is a sacrificial erosion wall, and users should not be concerned if they are seeing wear, this is
designed to support the erosion caused by unburnt particulates (especially in short barrel platforms) and is
