Laptops with a case made of metal and plastic

Aluminium with plastic

— case made mostly of plastic, but including metal elements — most often the outer part of the lid and/or the top side of the lower half (including the base of the keyboard and the space on the sides of the touchpad) . Plastic, usually, is used matte, and the most popular metal is aluminium.

For more information about all of these materials, see the relevant help items; here we note that their combination allows to some extent to combine the advantages and mutually compensate for the shortcomings. So, such combined cases look good, they are more durable than all-plastic ones, and at the same time not as expensive as all-metal ones.
