What is the Strongest Aluminium Alloy

 

Among the aluminum alloys, the strongest series belongs to the 7000 series of aluminum alloys, especially the 7075 aluminum alloy. This aluminum alloy has extremely high strength, and its tensile strength can reach more than 572MPa, and even theoretically 900MPa (but it needs to go through a specific injection molding process).

what is the strongest aluminium alloy

The following is a point-by-point introduction and summary of the strength characteristics of 7075 aluminum alloy:

Tensile Strength: The very high tensile strength of 7075 aluminum alloy is one of its remarkable features, its tensile strength is ≥ 572 MPa, and even higher values can be achieved under certain conditions.

Major Alloying Elements: The major alloying elements of 7075 aluminum alloy include zinc, copper and magnesium. The addition of these elements and the proportionality between them have a direct effect on the strength of the alloy. In particular, when the ratio of zinc and magnesium is appropriate, MgZn2, which has a significant strengthening effect, can be formed to further improve the strength of the alloy.

Cold-treated wrought alloy: 7075 aluminum alloy is a cold-treated wrought alloy, and its strength can be further increased by cold deformation treatment. It is also one of the strongest alloys commercially available, with strength far superior to that of soft steel.

Other Properties: In addition to its high strength, 7075 aluminum  plate alloy has good corrosion resistance, mechanical properties, and anodic response. Its fine grain size allows for better deep drilling performance and increased tool wear resistance.

Application Areas: Due to its high strength and excellent overall properties, 7075 aluminum alloy is widely used in aerospace, automotive, bicycle, shipbuilding, and other areas where high strength materials are required. For example, aircraft beams often use this alloy.

In summary, 7075 aluminum alloy is one of the strongest aluminum alloys known, and its high strength and excellent overall performance make it an important material for many high-end applications.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay
