Laptop shell material mainly includes three categories: hardness plastic shell, metal alloy and carbon fiber alloy. Early laptop computers are mostly hard plastic shell, its weight, not high strength and poor heat dissipation. At the beginning of the use of the time is not a problem. But with a long time, there will be different degrees of wear and deformation, with a hand press shell, as if it were a drum skin can be sunk and then popped up, a good number of reinforced plastic will not appear in this case, but there will be a certain degree of wear and tear after a long time. In addition to a small number of low-priced laptops on the market today, the vast majority of manufacturers have abandoned the use of this material.
Better than reinforced plastic is aluminum alloy, which is mainly divided into aluminum-magnesium alloy and titanium alloy according to the different alloy components. At present, most manufacturers use the most silver-white magnesium-aluminum alloy. In fact, magnesium-aluminum alloy is not very strong and wear-resistant, the biggest reason for the use of this material is that the heat dissipation effect is very strong at the same time lower cost. For the use of magnesium-aluminum alloy material for the main advantages of the laptop is light and thin, the disadvantage is the use of a long time, the original silver-white color will wear off, revealing its dark gray original face; if accidentally scratched, that the scar will also be very conspicuous. In order to solve the problems encountered magnesium aluminum alloy, engineers have introduced the space metal titanium into the laptop shell material. Titanium metal is a product of the space age, wear resistance is very good, before it is mainly used for those who require high strength, low weight applications of special occasions, such as aerospace components, aircraft manufacturing and medical equipment. The emergence of titanium-aluminum alloy laptop shell at the same time to solve the problem of heat dissipation and abrasion resistance, does bring certain benefits to consumers, but according to my understanding, most of the market using this alloy material products in the proportion of titanium is also only in about 2%. From the subjective feeling, the alloy material touch and plastic material touch to have a big difference, off when the alloy material is cold, after a period of time, the alloy of the machine heat dissipation is good, the surface feel the temperature is higher.
