High-strength aluminum alloy is what aluminum alloy main product classification

What is a high-strength aluminum alloy ? High-strength aluminum alloys generally refer to ultra-hard, high-strength aluminum alloys made of aluminum, zinc, magnesium, and copper alloys. High-strength aluminum alloy refers to aluminum alloys whose tensile strength is greater than 480 MPa, mainly rust-proof aluminum alloys, hard aluminum alloys, superhard aluminum alloys, wrought aluminum alloys, and aluminum-lithium alloys in pressure-treated aluminum alloys. . With the rapid development of the industrial economy, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also intensified. At present, aluminum alloy is the most widely used alloy. Let's take a look at the major categories of aluminum alloys.

High strength aluminum alloy

High-strength aluminum alloy refers to aluminum alloys whose tensile strength is greater than 480 MPa, mainly rust-proof aluminum alloys, hard aluminum alloys, superhard aluminum alloys, wrought aluminum alloys, and aluminum-lithium alloys in pressure-treated aluminum alloys. .

Aluminum alloy application

All kinds of aircraft use aluminum alloy as the main structural material. The skin, beams, ribs, purlins, bulkheads, and landing gear on the aircraft can all be made of aluminum alloys. The amount of aluminum is also different depending on the use of the aircraft. Civil aircraft, which focuses on economic benefits, are used in large quantities because of the low price of aluminum alloys. For example, the aluminum alloy used in the Boeing 767 passenger aircraft accounts for approximately 81% of the weight of the aircraft's body structure. Military aircraft have relatively reduced use of aluminum due to their requirements for good combat performance. For example, the F-15 high-performance fighter with a maximum flying speed of Mach 2.5 uses only 35.5% aluminum alloy. Some aluminum alloys have good low-temperature properties and are not cold and brittle at -183 to -253 [2 oc]. They can work in liquid hydrogen and liquid oxygen environments. They have no chemical reaction with concentrated nitric acid and unsymmetrical dimethyl hydrazine. The welding performance is thus a good material for making liquid rockets. The fuel tanks, oxidizer tanks, chamber sections, inter-stage sections, tail sections and instrument chambers at various levels of the Saturn V launch vehicle launching the Apollo spacecraft are all made of aluminum alloys.

The crew compartment of the space shuttle, front fuselage, mid fuselage, rear fuselage, vertical tail, flaps, lift ailerons and horizontal tail are made of aluminum alloy. The main structural materials for various man-made earth satellites and space probes are also aluminum alloys.

Aluminum alloy main product classification

1. Aluminum alloy profiles

The aluminum and aluminum alloy materials obtained through extrusion processing can be made of plates, rods and various special-shaped profiles, and can be widely used in new materials such as construction, transportation, transportation, and aerospace.

2. Aluminium plastic board

Aluminium-plastic panel is a new type of material that is surface-treated and coated with 3003 aluminum-manganese alloy, 5005 aluminum-magnesium alloy sheet as surface, PE plastic as core layer, and polymer adhesive film composited through a series of processes. It not only retains the main characteristics of the original constituent material (aluminum alloy plate, non-metallic polyethylene plastic), but also overcomes the deficiencies of the original composition material, and thus obtains many excellent material properties. Product features: bright and colorful decorative, weathering, corrosion resistance, resistance to hit, fire, moisture, noise, heat insulation, shock resistance, light weight, easy processing and molding, easy handling and other characteristics.

3. Aluminum sheet

Aluminum veneers are processed with high-quality aluminum alloys made by world-famous large enterprises, and are then surface-sprayed with US PPG or Aksu PVDF fluorocarbon paints. The aluminum veneers are mainly composed of panels, reinforced bones, and hangers.

4. Aluminum honeycomb panels

The aluminum honeycomb panel adopts a composite honeycomb structure, and a high-quality 3003H24 alloy aluminum plate or 5052AH14 high-manganese alloy aluminum plate is used as a substrate, and the aluminum alloy honeycomb core material is hot-pressed and compounded. Aluminum Honeycomb panels provide architects with rich choices in terms of panel materials, shapes, seams, mounting systems, colors, and surface treatments. They can display a wealth of roof performance and have excellent design freedom. It is a new material with convenient construction, ideal overall performance and remarkable heat preservation effect. Its excellent performance has attracted people's attention.

The above points are the summary of this site for everyone to summarize high-strength aluminum alloy, aluminum alloy main product classification related information, I believe we will have a certain understanding after reading, so that everyone will know a lot, if Everyone who wants to know can check it out on our website.
