Engine Parts

1. The car's engine are usually die cast iron, some advanced engine with magnesium, aluminum alloy, so some lighter, reduce vehicle weight, and heat dissipation is better than cast iron.

2. The difference between the titanium magnesium and magnesium alloy:

A, aluminium magnesium alloy:

(1) aluminum magnesium alloys generally is the main element, and then mixed with a small amount of magnesium and other metal material to enhance its hardness. Because itself is metal, especially the performance of thermal conductivity and strength. Aluminium magnesium alloy quality, and the strong and lightweight, low density, heat dissipation is good, strong resistance to pressure, can fully satisfy 3 c products are highly integrated, lightweight, miniaturization, fight broke into and electromagnetic shielding and cooling requirements. Its hardness is several times of traditional plastic casing, but the weight was only about a third, usually used in high-grade ultra-thin or smaller notebook shell. Also, silver-white magnesium aluminum alloy shell can make the products more luxurious, beautiful, and easy to color, can through surface treatment technology into personalized powder blue and pink, for laptops graces many, this is engineering plastic and carbon fiber. Aluminum and magnesium alloy became the shell material of choice for portable laptop, at present most vendors notebook product adopts the technology of aluminium magnesium alloy shell.

(2) disadvantages: magnesium alloy is not very strong wear resistance, high cost, relatively expensive, but molding difficult than ABS (need) by stamping or die casting process, so the laptop only commonly aluminum magnesium alloys used in roof, there are few models with aluminium magnesium alloy to make the entire chassis.

Second, titanium magnesium alloys:

(1) titanium magnesium alloy material can be enhanced aluminium magnesium alloy, titanium magnesium and magnesium alloys in addition to adding different metal itself, one of the largest, respectively is also infiltration of carbon fiber material, regardless of the heat dissipation, strength and surface texture is better than that of aluminum and magnesium alloy material, and processing performance is better, than aluminum magnesium alloy is more complex and changeful shape. The key breakthrough is strong toughness stronger and thinner. Just strong toughness, three to four times that of magnesium alloy titanium magnesium alloys. The higher the strong toughness, can withstand the pressure, the greater the more able to support large size display. Titanium magnesium alloy models, therefore, even if equipped with 15 inch monitor, also need not obligate too wide around the panel frame. As for thinness, titanium magnesium alloy thickness is only 0.5 mm, is half of the magnesium alloy, the thickness of the half can make laptops more petite size.

(2) disadvantages: the only downside is that must pass welding titanium magnesium alloys such as complex processing procedures, can make complex laptop case, these significant costs are derived from the production process, so is very expensive. At present, the titanium titanium magnesium alloys and other composite materials is still IBM special materials, it is also one of the reasons for IBM notebook computer is more expensive.
