The difference between aerospace aluminum sheet and ordinary aluminum sheet
Aviation aluminum sheet is a kind of ultra-high-strength deformed aluminum sheet, after which it is currently widely used in the aviation industry.
It has good mechanical and processing properties, good plasticity after solution treatment, and good heat treatment strengthening effect.
Generally, it has high strength and toughness below 150°C (or even higher) and is an ideal structural material.
In addition, compared with ordinary aluminum plates, aircraft aluminum plates have higher requirements for strength, hardness, toughness, fatigue resistance, and plasticity.
Due to its lightweight and remarkable lightweight effect, aviation aluminum has replaced steel and occupied the currently leading position of aviation materials.
Aviation equipment has high requirements for aluminum, which is an important high-end application market for aluminum.
Many kinds of aluminum plates use on airplanes.
In today’s world, the main types of aluminum plates used in aviation aircraft structures are high-strength 2 series (2024, 2017, 2A12, etc.) and ultra-high-strength 7 series (7075, 7475, 7050, 7A04, etc.). ), of course, there are also some 5 series (5A06, 5052, 5086, etc.) and 6 series (6061, 6082, etc.) and a small amount of other series of aluminum.
All in all, aerospace aluminum is mainly used for wing surface skin, wing surface girders, wing spars, webs, fuselage girders, seat slides, keel beams, side frames, fuselage skins, and lower fuselage Upper and lower edge strip wall panels, main floor stringers, etc.
1. Duralumin: aluminum-magnesium-copper alloy
The most widely used aluminum sheet in the aviation industry. Commonly used 2024, 2A12, 2017A, strength, toughness, fatigue resistance, similarly, have good plasticity. Used to make skins, bulkheads, ribs, etc.
2. Superhard aluminum
Aluminum-zinc-magnesium-copper alloy. For example, the commonly used 7075 and 7A09 have high ultimate strength and yield strength, and high load, they are used to skin the upper wing surface and beams.
3. Anti-rust aluminum plate
Commonly used aluminum-magnesium alloys 5A02, 5A06, 5B05. It has high corrosion resistance, fatigue resistance, good plasticity and weldability. Therefore, it uses to make mailboxes, oil pipes, etc.
4. Forged aluminum plate
Of course, the commonly used 6A02 has high hardness and good corrosion resistance. Manufacturing engine parts, joints, etc.
5. Cast aluminum plate
low specific gravity, high corrosion resistance, and heat resistance, manufacturing engine casing, etc.
Oh my goodness! an amazing article dude. Thank you Nevertheless I am experiencing problem with ur rss . Don’t know why Unable to subscribe to it. Is there anyone getting equivalent rss drawback? Anyone who knows kindly respond. Thnkx
