After Apple rolled out IPhone 4s 2011 oneself, from IPhone 5 till last year (2017) , never roll out the IPhone with stainless steel qualitative material. Nevertheless last year, IPhone X uses Apple10 anniversary fund however stainless steel and glass serve as main material, be regarded as the IPhone XR of introductory money generally this year, it is the design that keeps aluminium alloy.
Belong to metallic ability to pledge likewise, why should Apple use stainless steel and aluminium alloy respectively as divisional and high-ranking money and second rank money mobile phone? And although rare mobile phone uses stainless steel on market,make, why is Apple still determined to use stainless steel on IPhone X and IPhone XS?
Stainless steel is a kind of very outstanding metal stuff, have fight formidably corrode character, after passing polishing technology, can have very beautiful burnish, the key also depends on it very solid. In fact, the aluminium alloy of the outclass that fight a gender of stainless steel, this also is why stainless steel becomes the first selection material of a lot of high price high-quality goods to pledge, for example commodity of wisdom of spare parts of high-quality goods watch, car, high end science and technology.
Nevertheless, the weakness of stainless steel is apparent also. Because of the relation of density, even if falls in same unit weight, is aluminium compared normally? ? What the steel of every unit comes is costly, but make an appointment with 2.5 times under steel as a result of aluminous density, because this is below same volume, the cost that aluminium controls comes cheaply than steel instead.
In addition, aluminous character is softer than steel, extend a gender admirable also, because this processes cell of make it mobile phone more easily, apple ever had revealed aluminium to control the making process of crust when the year before last year rolls out IPhone 7, reveal a factory how to make the airframe of IPhone 7 through CNC machine, if IPhone 7 converts,stainless steel makes airframe, that cost and process will become more costly, trival.
The aluminous metal that contemporary wisdom mobile phone uses, be not pure aluminium, because aluminium is too soft, because this need adds a variety of metals,mix " aluminium alloy " come aggrandizement hardness. Current, the existence on market exceeds 500 kinds of aluminium alloy, every kinds of aluminium alloy has exclusive character and metallic content, common aluminium alloy serves as number to express with 4 digit word more.
As we have learned, apple IPhone 6 uses number namely the aluminium alloy of 6003 is made, and more advanced type is the aluminium alloy that employs 7000 departments, for example SamSung (Samsung) Galaxy S9 uses 7003 aluminium alloy, Apple Watch namely also is to use 7000 departments aluminium alloy.
Because aluminium alloy compares stainless steel to come gently, and easy heat conduction, easy chromatically, because this makes the optimal choice of IPhone of Apple low cost, IPhone XR can be rolled out at a heat this year amount to 6 kinds of color, do obeisance to the characteristic be caused by of aluminium alloy namely. And the price is high, take the IPhone XS series of high-end course, use simple sense relatively the stainless steel of beautiful, with dash forward show its to symbolize exaltedly.
