AMS 4904, since an ideal light in weight material, the possible advantages become even more and more obvious. As a result, in recent years, an increasing number of aluminum profiles are utilized in the aerospace field. In accordance with statistics, the space launch automobile into space orbit weight per offset one kg, launch costs will preserve about $ 20,000, so the structure is known as each and every gram is important in the aerospace field. In the event that the weight of the fighter is 15 percent lighter in weight, well then the aircraft roll can reduce the distance by fifteen percent, and a journey twenty percent increase, and increase payload by thirty percent. For that reason, all countries in the entire world attach utmost importance to the research and development of aerospace light in weight structural materials. AMS 4904, as a consequence of its own lightweight, higher strength, easy to process, as well as the price of economic features, is of specific concern. Performance Properties of Aluminum - At present, in the course of the design of the aircraft, the designers are mainly will choose possessing a high specific strength as well as stiffness of the structural material, to be able to lessen the structural weight of the aircraft, to make improvements to the flight performance, as well as increase cost efficiency. At the same time, the structural material must also have good process ability as well as easy to make the parts required. Currently, a number of different aircraft aluminum alloy such as AMS 4965, AMS 5663 is utilized as the major structural material. Aircraft in compliance with the various uses, the amount of aluminum is all different. The civilian models pay attention to the economic advantages of a large number made out of aluminum alloy, part of that is because aluminum alloy cheap. For example the Boeing 767 with aluminum alloy accounts for around eighty one percent of the body weight of the structure. Military aircraft as a result of the requirements of good operational functionality relative to minimizing the amount of aluminum, for example high-performance F-15 fighter just 35.5% aluminum alloy. Aluminum is Commonly Used in Aerospace - Aluminum alloy such as AMS 5663, AMS 4965 in aerospace applications enhancement can be divided into a number of stages : the 1950s, the primary goal is to lose weight as well as make improvements to alloy stiffness as compared to strength; from the 1960s to 1970s, the primary goal is to improve the alloy toughness and damage tolerance created 7XXX series alloy T73 as well as T76 heat treatment system, the 7050 alloy and also high-purity alloys; in 1980s, because of rising fuel prices and need to have further lessen the structural weight; since the 1990s, the enhancement goals of the aluminum alloy is even further weight loss, and furthermore improve the alloy durability as well as damage tolerance. Similar to the development of a high-strength, high corrosion resistance, a completely new aluminum alloy, a sheer number of heavy plate processing into intricate overall structural parts rather than before, with many different parts assembly parts, not simply could reduce the weight of the structure, but in addition to guarantee the constancy of the performance and available at Flight Metals.
