Aluminum alloy has the characteristics of light specific gravity, high specific strength, low cost, easy processing, and corrosion resistance. It has long been an indispensable key structural material in the global aerospace field.
In the contemporary aviation manufacturing industry, aluminum alloy has always been one of the most important materials in the aircraft body structure, and its consumption accounts for about 40% to 70% of the weight of the body structure.
Aviation aluminum alloys mainly include high-strength/ultra-high-strength and high-toughness Al-Zn-Mg-Cu series (7xxx series), medium-high strength damage-resistant Al-Cu series (2xxx series), medium-strength weldable Al-Mg-Si series (6xxx series), and high specific strength and high specific modulus lightweight Al-Li alloy and a small amount of other aluminum alloys.
The 6xxx series aluminum alloys used in aviation have successively developed alloys such as 6061-t6 aircraft grade aluminum, 6063, 6016 and 6056 aluminum alloy, which are used in aircraft protection plates, skins, flanges and other parts. Although 6000 series aluminum alloys such as 6061 and 6063 have low strength, they have good ductility, and are often used in body skeletons and outer frame structural parts, bolt components, and outer frames of doors and windows.
6061 aluminum alloy is widely used in aerospace, machinery, power electronics and household appliances due to its advantages such as high strength, strong corrosion resistance, low stress corrosion cracking tendency, good formability and process performance.
In the past, domestic aircraft system ducts mostly used LF2-M and LF21-M materials, while foreign countries mostly used 6061-T4 and 6061-T6 aluminum alloy. 6061 aluminum alloy has higher strength than traditional anti-rust aluminum alloy, which can make the pipe wall thickness thinner and the system weight smaller.
Aircraft maintenance climbing ladders are generally composed of ladder frames, handrails and pedals. It is assembled and built from aluminum profiles, mainly using 80 series aluminum profiles. The aluminum profile is extruded from 6063-T5 aluminum. After anodizing and sandblasting, it has good corrosion resistance and is easy to clean.
6063 aircraft grade aluminum is a heat-treatable strengthening alloy with medium strength in the AL-Mg-Si system, and Mg and Si are the main alloying elements. 6063-t6 aluminum has a tensile strength of over 205Mpa and yield strength of over 180 Mpa. It has a wide range of applications, especially in the construction industry. Welcome to leave message below to inquire what you need.
