Aluminum Foam Sandwich Panel

Short Description:

Aluminum foam material is the middle sandwich layer, the upper and lower layers are aluminum sheet,and the interlayer is bonded by high temperature and hot pressing.

It has light weight, high specific stiffness, aging resistance, good energy absorption and impact resistance.

By adjusting the material and size of aluminum foam and aluminum sheet, It can meet different performance requirements of car structure, floor, box, building, furniture and other fields.
