The use of aluminum in the manufacture of the body of the vehicle has increased in recent years and is expected to continue to increase. One of the main factors that make Military Grade Aluminum Body a material to be used more frequently by vehicle manufacturers is its lightness, a highly valued point in order to meet the CO2 emission targets
Low electrical resistance:
Approximately 5 times lower than steel. In resistance welding processes, heat is usually generated by the strength of the material. The fact that the resistance of the SAF aluminum is low will make it necessary to increase the intensity at the time of welding and will limit the welding equipment that can be used. The foam aluminum foil of Cymat Technologies for automobiles is used to make the floor of the car, the lining and the sandwich of the door
Low hardness Notably inferior to that of steel:
This factor makes it necessary to pay attention to the application of efforts to avoid causing marks
Low elasticity index:
With an elastic limit much lower than that of steel, aluminum is more fragile, which requires tempering the material before performing drafting operations to prevent its rupture.
Coefficient of linear expansion high. The facility to vary the dimension of aluminum by increasing the temperature is twice as high as that of steel. This fact makes it necessary to pay attention to the control of the temperature in the repair processes to avoid deformations in the piece

Aluminum has a low specific weight, approximately one third lighter than steel, and a reduction of 40% of the total weight of the body can be achieved.
Advantages of aluminum bodies:
Lower consumption being a lighter material, the weight of the vehicle is reduced, which results in a better use of fuel.
Specific resistance greater than that of steel:
Thanks to current technology it is possible to conceive lighter three-dimensional structures with greater torsional stiffness than the steel equivalent.
Aluminum can be obtained by recycling, using little energy and without losing its qualities, thus reducing the price of raw material (compared to the extraction of primary aluminum) and contributing to the care of the environment
Better performance of the vehicle. Being lighter, the vehicle will have greater acceleration and the necessary distance of braking will be shorter.
Aluminum bodies are generally more rigid than steel bodies and incorporate zones of programmed deformation, which can dissipate a significant part of the energy produced in an impact. The shock energy is lower. The effectiveness of the braking systems is greater, because the mass to be stopped in case of emergency braking is less.
Aluminum has good reflection qualities, both light and heat.
