NRF is a manufacturer a wide variety of aluminum cooling parts. All produced in our own European production facilities. NRF’s aluminum coolers are known for the high quality and durability. Because we manufacture all coolers by ourselves, we can a wide variety of sizes and multiple fin systems.
Our cores are manufactured by using aluminium alloys such as series 3XXX, which provides a great performance in terms of:
Corrosion resistance
Mechanical properties
Weldability
Light weightiness
5XXX and 6XXX alloys are mainly used either formed and extruded in other components such as brackets, tubes, frames, and tanks.
Soldering or brazing?
Soldering makes a joint between base metals by melting only filler material, which wets base metal surface because of capillary action. The solder melts at a temperature below 450°C
The heating sources such as torch, furnace, and induction coil are used in different steps of our process to achieve the best result in each component as well as the composition of the filler material.
ADVANTAGES
Soldering process has a lower power input and processing temperature compared to other processes.
It is one of the best options to join dissimilar base materials
Being able to join thin-walled parts
Soldered joint has a minimal thermal distortion and residual stresses in the joints
Not needing a post-processing heat treatment
