However, this material is of low intensity, not heat, to achieve the required strength of the phone, you have to have a certain thickness (metal skeleton of the year has not the concept), and this makes the phone hard to light, so when the phone frequently 20mm, flip phone is not uncommon 25mm.

In addition, this material once the paint off the surface will seem very low, so careful selection of high-end mobile phones generally, and now the phone has been used very little.

PC is the abbreviation of polycarbonate, although Nokia bragging seem tall, but in fact we use buckets vat is this material. This strength than ABS plastic good, the same intensity can be made thinner than some ABS plastic. Heat better than ABS.

However, this material is not easy to paint, surface treatment is also difficult, generally used in slightly higher level phone. Do you like these unique iphone 5/5S cases? You can buy them on icases-shop.com.

A plastic is always difficult to achieve the desired effect, so people would engage in out double injection, a cell phone with two kinds of plastic, with an inside surface hardness and better in a transparent plastic, so that the color has been closed transparent plastic below the phone's tactile and visual feel would be better.

In general, low-cost plastic phone, processing simple, but because the intensity of reasons some heavy, double injection can not do too thin. This function machines previously indifferent, to the era of the big-screen smart machines, people began to look for something better.

Metallic materials - stainless steel and aluminum

Since the plastic-strength low-thick, thinner you have selected high strength, which is a metallic material. The metallic shielding material, affect the signal.

The solution is to increase the strength of the skeleton made of metal, glass or plastic or housing. (Hammer T1 signal in order to be better, with the skeleton of glass fiber composites)

Do not think a simple steel and aluminum, the number has more than 100 kinds of steel, stainless steel, there are dozens of aluminum from one system to the 9 series, each series has a number of models.

This phone is not too high intensity stuff, usually choose 304 or 314 stainless steel and 6 series aluminum alloy.

From the strength to say, these models are not the best choice. But relatively soft austenite 304 easily processed, not magnetic, the price is cheap, so millet 4 used. 6 series aluminum alloys, although not as strong as the 7 Series, but welding, painting, molding properties are good, integrated low cost, so Apple used.

Late, as technology advances, people gradually find the antenna arrangement scheme, Full Metal Jacket phone also has the latest iPhone6 is. This phone's high-grade plastic than many.
