Aeronautical aluminum material refers to a variety of aluminum alloys used in the manufacture of aircraft, including wrought aluminum alloys and cast aluminum alloys, and advanced aluminum alloys. Wrought aluminum alloy is used to process semi-finished products such as plates, belts, tubes, bars, bars, wires, forgings and powder materials. Cast aluminum alloys are used in the manufacture of die castings. They are used in various parts of deep processing aircraft. Aircraft refers to the 100 kilometers away from the ground in the atmosphere of flying instruments, such as aircraft, helicopters and so on.

The "five engines" in this article refer to the ARJ21, the C919, the Y-20, and the large jet. They are often referred to as "big planes". The other two engines are all military aircraft and general aircraft. From 2015 to 2035 20 years is a period of great development Chinese aviation industry, will also be the five plates of high speed continuous period of steady growth, and will boost demand for gold aluminum into the stage, at this stage the compound annual growth rate of up to 10%.

ARJ21 and Xinzhou 60 type aircraft

March 2015, ARJ21-700 aircraft completed the first flight demonstration flight, in November 29, 2015 formally delivered to Chengdu airlines. According to the Shanghai aircraft manufacturing plant plan, by the end of 2016, there will be 5 completed delivery, of which 2, 90 seat, 3, 78 class, is expected in the next five or six years will be completed 30 deliveries. To 2035, 550 can be delivered, each with about 42 tons of aluminum.

In the period from 2015 to 2035, Chinese may 400 MA60 aircraft manufacturing series, its structure is almost entirely Aluminum Alloy, the rate of aluminum can be 80% calculations, each aircraft aluminum amount 25 tons according to the calculation needs about 10 thousand tons of aluminum.

C919 trunk airliner

The structure of C919 front fuselage, the fuselage, rear fuselage, nose wing and almost all aluminum manufacturing, and engine hanging, tail, tail, fuselage frame, the front and the rear pressure after the machine behind section, the central wing is made of composite material or titanium alloy forgings.

As of December 2015, C919 aircraft users at home and abroad is 21, the number of orders of 520 aircraft, priced at about $50 million / $90 million, than the Boeing 737 / 45% cheaper, at the same time, first flew in 2016 after breaking the Chinese aviation market of Boeing and Airbus monopoly. In the next 20 years, may 1200, put the amount of each frame according to the estimated 75 tons of aluminum, the need to purchase 90 thousand tons of aluminum.

-20 heavy military transport aircraft

-20 (China Code Name: Y-20, Kun Peng) large jet conveyor is a new generation of heavy military aircraft independently developed by china. If the net quality of Y-20 is 154 tons, the rate of aluminium is calculated by 70%, the quality of aluminum parts is 108 tons, and the utilization ratio of material is 50%, so it will need to invest 216 tons / shelf.

From the demand for rescue, disaster relief, troop build-up and armed forces delivery of the PLA, the number of China's demand for -20 will be enormous. In only one batch of cargo, if you need to put a Panzer brigade in the main battle direction, the two airborne armoured regiment, plus 1500 paratroopers and the associated assault vehicles, command vehicles, helicopters, there is at least about 250 of the -20. The actual demand for the -20 transported by the Chinese military is at least 300 or more. On such a large scale, two aircraft factories will be able to produce 64800 tons of aluminum for 10 years at full capacity.

warcraft

China military aircraft from the last century at the beginning of 50s all introduced from Soviet MIG -15 fighter (Combat) machine, the independent research and development of the third generation fighter Xiaolong /FC-1, the material of aluminum has been play a leading role, the vast majority of northeast light alloy limited liability company in the aluminum company, Southwest aluminum (Group) Co. the company, Northwest Aluminum processing plant.

The military aircraft is a huge family, including fighter planes, bombers, and so on. Although the overall aluminum is still the main material, but the trend is the proportion of aluminum in a single machine on each generation, and the composite material and titanium alloy etc. the proportion will rise accordingly, such as the fourth generation of F-22 and F-35, by stealth, supersonic cruise capability, high in the distance, mobility and combat capability STOL capability and low maintenance cost for the characteristics, in their material, titanium alloy, composite materials and stealthy materials and is more than aluminum.

Estimated during 2015 ~2035, Chinese need to add about 3400 aircraft of various military aircraft, their total estimated demand for 120 thousand tons of aluminum.

General aircraft

The author said the general aircraft refers to the addition of ARJ21, C919, military aircraft outside of all aircraft, a variety of names, complex, be too numerous to enumerate in the period from 2015 to these estimates, in 2035 the total demand of about 210 thousand tons of aluminum.

Aluminum in aircraft consumption: about 60% of rolled material, about 28% of extruded material, about 7% of forgings, about 5% of castings. This ratio is the average, in different aircraft will have different proportions, and some even very different.

Chinese aircraft manufacturing industry has made great progress, but with national needs, power required, power required number of aircraft performance and there is a large gap compared with the United States, has a large gap, must try to catch up, catch up with the US in the next 20 years is a period, is also Chinese aviation industry sustained rapid development period. Aluminum is still the main material of the aircraft, and during this period, the amount of aluminum used by civil aircraft will be greater than 70%, and no less than 55% of the military aircraft. Aluminum will be subject to the challenges of composite materials, but the amount of substitution will not be large, and in the foreseeable time, aluminum is still the most cost-effective aviation materials. However, the aluminum industry should not be taken lightly, we must strengthen research and development, strengthen innovation, research and development of new alloys, and create new materials processing technology.

此外，航空铝材生产企业宜与航空器制造企业合作，建设航空铝零件深加工生产能力，为它们提供可直接进行组装的零部件，这将大大提高企业的经济效益与产品市场竞争力。
