Aerospace Aluminum Plate

Aerosapce aluminum plate



      Aluminum offers a high strength-to-weight ratio, energy efficiency, and high tolerance to extreme temperatures- making it an ideal material for the manufacturing of aircraft. It can also be recycled repeatedly, making it a good choice as manufacturers pursue sustainability initiatives.

    Aluminum plate is an important structural material for aircraft, and it is mainly used in fuselage, wing skin, oil tank etc. By using aluminum composite materials, the density of aircraft’s outer skin can be decreased by 5%-7%. As a result, the total weight can be reduced 10%, and therefore fuel efficiency increases. Moreover, 7% can be increased in stiffness of the material by using aluminum plate. Due to the superb corrosion resistance, fatigue resistance and damage tolerance of alunimium alloy, the inspection period can be extended and hence decreasing maintenance cost.



    Depending on the state-of-the-art manufacturing technology, Signi aluminum plate is capable of providing various aluminum alloy products for aviation industries, such as wing skin, fuselage, stringer, chair skid, and augmented satellite launch vehicle etc.

Packing
Aluminum Plate : Aluminum Plates are placed in wooden boxes on wooden skids with runners along the length of the sheet. They are wrapped in HDPE with hardboard on top and bottom of the stack. Hoop iron strapping runs along the length of the sheets. Silica gel packets are put in the boxes for moisture protection.(Aluminum plate)

    Signi aluminium supplies aluminium sheet and aluminium plate material for fuselage and wing structure components according to standard or customized specifications.
 
    Signi Aluminium has introduced new low density alloys – lithium and scandium-containing aluminum alloys – which represent an innovative step forward for aluminum in aerospace.  Weight-savings from these new alloys translate into fuel efficiency and lower operating costs for the airline industry.

 
    Signi Aluminium has been serving the aerospace industry for more than ten years from its world class aluminum plate mill in China.  Among the most important aerospace aluminum plate facilities in the world, Signi Aluminium is backed by a leading research and development team that works with customers to deliver new solutions to the marketplace.  The Signi Aluminium plant also served as the blueprint for the company’s world class rolling mill in Zhengzhou, China, which began serving the aerospace industry in 2014.
 
    Signi Aluminium manufactures many different aluminum plates in various standard and customer-specified alloys using some of the world's most advanced hot and cold rolling mills.  With a 160-inch (4.064 m) hot rolling mill and a 148-inch (3.760 m) cold rolling mill, we can produce very wide and ultra-thick plates, either heat treated or non-heat treated. High-quality aluminum plates from Signi Aluminium meet the most demanding standards, plus many individual customer specifications.
 
    We have continued to expand our production capabilities to better serve global customers.  The state-of-the-art plant, one of only a handful in the world, is equipped to produce the most advanced value-added aluminum material for aerospace and leading manufacturers in a variety of fast-growing industries in China and worldwide.

 
    Our investment in a full-scale direct-chill (DC) pilot caster at our facility in China, illustrates our commitment to increasing our leadership in technically demanding industry segments.  The specialized facility is able to cast full-scale ingots for trials as well as for serial production of aluminum-lithium products.
 
    Our innovation centers in Zhengzhou, China, in particular focus on the aerospace industry and have developed innovations in aerospace that include high-strength alloys for structural aluminum plate applications and Aluminum Magnesium Scandium alloys for lighter fuselage sheets associated with new joining and forming technologies.
