In the past year, thanks to the strong growth of the aviation industry, the world aviation titanium alloy and carbon fiber composite materials market continues to rise. In July 2015, Alcoa (AA) spent US$4.35 billion in less than nine months to complete the acquisition of British Fortune, TITAL and RTI International Metals, and quickly placed aviation titanium alloys. And the 3D printing market. In August 2015, Buffett announced that it would acquire Precision Castings (PCC) for $37.2 billion and enter the aviation manufacturing industry. In the face of competition from capital giants, Alcoa made a spin-off decision in September to accelerate the transition to downstream metal services and processing companies, and the company signed a $9 billion in aerospace industry in 2015. The contract for medium and long-term supply has become the key to its transformation.
In December 2015, Solvay Belgium spent US$5.5 billion to complete the acquisition of US Cytec and took the second place in aerospace composites suppliers. Affected by this, Hexcel Corporation in January 2016 also bought a full purchase of half of the British Formax company a year ago. In addition, in July and August 2015, Canada's Avcorp Industries and the UK's Meggitt Company respectively proposed the acquisition of the composite materials business of Germany's SGL's Hitco and Cobham, further agitating the carbon fiber composite supply chain. .
New passenger aircraft, helicopters, drones and engines have been difficult to find aluminum alloys from the outside. As these models gradually enter full-speed batch production, the use of aviation titanium alloys and carbon fiber composite materials will continue to grow, which makes the aviation basic supply system The result has become a matter of nailing. The result is likely to be that the four-tier supplier at the bottom of the aviation material supply chain has a monopoly on the industry and is over the top contractor at the top of the pyramid, and even has an important influence on the right to speak in the future product development. In 2016 and in the next few years, a broader integration and deeper restructuring will be an important milestone in the historical transformation of aviation manufacturing from farewell to aluminum and steel to titanium and carbon.
In the past year, the struggle between metals and composites in aerospace manufacturing continues, with new bismuth aluminum alloys, titanium aluminum alloys, and microcrystalline nickel-phosphorus alloys and nano-ceramic magnesium alloys.
IBC Advanced Alloys' near net shape cast Beralcast material reduces the manufacturing cost of F-35 to a certain extent. The material is a bismuth aluminum alloy with 4 times the stiffness of ordinary aluminum alloy and only 1/5 of the weight. And improvements in materials and processes will reduce the cost of producing parts by 30% to 40%. In March 2015, the new titanium-aluminum alloy developed by MTU Engine Company over the past seven years combines the advantages of nickel metal and ceramic materials for turbine blade design, which is half the weight of existing nickel alloy components and greatly optimizes the turbine disk. Designed to achieve engine weight reduction. In October 2015, Boeing demonstrated the world's lightest metal structure. This micro-array structure of nickel-phosphorus alloy consists of a hollow tube structure with a wall thickness of only 100 nm and weighs only 1/10 of the carbon fiber. It is fully recovered after its volume is compressed by 50%, so it has an extremely high energy absorption capacity. In January 2016, UCLA and Raytheon jointly created a super lightweight structural metal consisting mainly of magnesium and infused with dense and evenly distributed ceramic silicon carbide nanoparticles in magnesium. Specific strength and specific modulus, and can be mass-produced.
New materials are one of the foundations for the development and transformation of aerospace manufacturing. The first two of the four new alloys are going to be used in large quantities for F-35 and geared fan (GTF) engines; the latter two are more revolutionary if Applied to aircraft manufacturing, it will completely subvert the existing aerospace product design. New materials will continue to emerge in 2016 and in the next few years, and they may soon reach a certain level of technology maturity and manufacturing maturity.
