The material of the shell of the notebook can be divided into two types: plastic and metal.In general, the composite material is ABS plastic, has the advantages of low cost, simple manufacturing process, easy molding, impact resistant performance is good, for the shortcomings of heavy and poor thermal conductivity, often used in mainstream price models; another typical plastic material is PC polycarbonate material the material, compared to the ABS engineering plastics for better thermal conductivity, the disadvantage is crisp texture, the Fujitsu notebook can often see the use of this type of materials.
