Application of aluminum foam（5）

Aluminum foam demand in the automotive industry

• Make car bumpers

The aluminum foam material is used as the core to make the car bumper, which has the function of absorbing the kinetic energy of the impact. The thickness of the aluminum foam core plate is generally 20mm, the density is about 0.6g/cm, and the aluminum foam material is deformed aluminum alloy. This bumper represents the general development trend of the world. The Audi A8 is already in use, and companies such as BMW, Mercedes and Honda are also developing applications.

•  making car floor, door sandwich, etc

The foam aluminum material is used to make car floor, spacer, door sandwich, etc., to achieve the effect of sound insulation and shock isolation.

•  the production of car floor

The foam aluminum material is used to make the floor, lining and door sandwich of the big car. It has good sound insulation, vibration isolation effect, light weight, heat preservation, corrosion resistance, long service life, no burning and good fire performance.

• Make a muffler

Aluminum foam sound absorption board is used to make mufflers for trucks, buses and cars. After fire-resistant treatment, aluminum foam sound absorption board can be applied to the tail gas temperature of 500 ~ 600℃. The noise reduction effect is 2 to 3 times that of the extended impedance muffler inner core and the parallel resonance muffler inner core muffler, and the weight is reduced by about 1/3.

• Make the body filled with aluminum foam profiles

The rigidity of the car body is increased by more than 2 times, and the damping and anti-collision ability is increased by more than 3 times.

•  the production of aluminum plate, aluminum foam, aluminum plate sandwich board car ceiling

The thickness of the sandwich plate is about 2mm, the stiffness is 7 times that of the steel ceiling, and the weight is reduced by more than 50%.

• the production of commercial car floor and car body

Using 10mm thick foam aluminum sandwich board to make commercial vehicle bottom plate and car body, compared with steel plate weight reduction of more than 50%, strength increased by more than 3 times, and corrosion resistance.
