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, HWALU 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.
Classic alloy：2024, 2324, 2524, 7075, 7475, 7050, 7150.
Product characters：high strength, high ductility, high damage tolerance.

| 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) |
HWALU aluminium supplies aluminium sheet
and aluminium plate material for fuselage and wing structure components according to
standard or customized specifications.
HWALU 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.
HWALU 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, HWALU Aluminium is backed by a
leading research and development team that works with customers to deliver new
solutions to the marketplace. The HWALU Aluminium plant also served as the
