2024 Aluminum Plate
This plate is made of an aluminum-copper alloy, with high strength-to-weight ratio. 2024 Aluminum plate is used for truck and aircraft wheels, truck suspension parts, and is useful in aircraft fusilage components. 2024 alloy does have limited weldability, but 2024 is less corrosion resistant than other alloys.
2024 alloy plate has good fatigue resisitance and is specified for many structural applications for aerospace, including fusilage structural components, wing tension structure, and shear ribs and webs.
- Fuselage structurals
- Wing tension members
- Shear webs and ribs
- Precision fittings
- Truck wheels and parts for transportation

PA THERMAL BREAKING PROFILES EXTRUSION LINE
Good insulation properties, current technology enables the
reduction of the thermal conduction U-factors (heat loss rate) of
a normal aluminium frame from over 4,5 down to 3W/m2 K.
Application in a wide range of temperatures (from – 30° C
to + 210° C). Nowadays a good aluminium window system must
be anodised or treated with powder paint, this means that the
assembled frame has to pass such operation which takes 15/20
min at 200°C, without undergoing any distortion.
Very good mechanical properties, the joint is responsible
for the mechanical connection of the interior and exterior window
frame, the final execution of the frame is proportional to this
Thermal expansion coefficient similar to aluminium material to
avoid internal stress that compromises the mechanical resistance
of the frame.
Last but not least a good process capability to attain an extruded
profile with tight tolerances.
This long list of characteristics reduces the choice to few
thermoplastic materials, among which the best solution is a
techno-polymer based on PA 6.6 reinforced with 25% fibreglass.
Once identified the raw material,
the extrusion technology can be developed for the efficient
production of the joint profile.
Single screw extruder is the best solution
to process PA + 25% fibreglass.
28:1 L/D ratio is suggested for a good melting of the
material; an accurate temperature control of the profile
is a must to keep a good tolerance on the final profile.
A special attention is given to problems due to wearing.
Adding 25% fibreglass to the material, special steel
and treatment must be used to reduce the wearing on
barrel and screw surface.
A particular screw design allows good performance and
the possibility to use up to 20% regrind material without
reducing the line performance and the final quality of
To achieve a good product, the extrusion technology
is a key point, only a great experience can guarantee
a good result .The kind of the raw material and the
required tolerances on the final product led to a
sophisticated multi-exit extrusion technology to achieve
high output.According to required hourly output and to
profile shape, 4 or 8 exit dies are used.
The size and output of the extruder are chosen according
to the required capacity of the line. The mainly used
extruders are EA 60, EA 70 and EA 90
I found this product on line at www.jjvsbest.com. I emailed back and forth with Victoria at Crow’s Nest Marine 763-479-3145 – very responsive and helpful. She shipped the material in time for me to try before I put the pontoon in for the summer. I had several pontoons over the past 25 years, I used Zing, Toon Brite and others – this is by far the best product that I have used to clean aluminum pontoon tubes! It worked great and just like they said! I think the video speaks for itself! Thanks Kurt – you did a great job!
