Aluminium alloy

With the continuous progress of science and technology, people's requirements for goods are getting higher and higher, and the strength problem is a key problem. For example, in construction, machinery and other fields, strength has always been one of z's priorities. Today, I will discuss that at the same cost, the hollow material of aluminum alloy is stronger than that of plastic steel.

First, aluminum alloy material introduction

Aluminum alloy material is a metal material made of aluminum and other elements, commonly used alloying elements are copper, zinc, magnesium, manganese, silicon and so on. Aluminum alloy has the characteristics of low density, high specific strength, strong corrosion resistance, good processability and easy surface treatment. In the material, the specific strength of aluminum alloy, forming ability, corrosion resistance and other aspects are very excellent.

Advantages of aluminum alloy material:

1. Small density, light weight

With a density of 2.7g/cm³, which is one-third that of steel, aluminum has a very small weight and excellent lightweight effect, making it an ideal material for the manufacture of light vehicles, aircraft and high-speed trains.

2. High intensity

Aluminum alloy is more prominent in terms of strength and specific strength, shear strength and tensile strength are better, and it is stronger than metal materials.

3. Good processability

Aluminum alloy can be processed in various ways, such as rolling, drawing, cold extrusion, etc. Welding, riveting, bonding, casting and other connection methods can be used.

4. Corrosion resistance

Aluminum alloy has good corrosion resistance, not only can withstand corrosion in the atmospheric environment, but also can be in a long-term stable state in acidic, alkaline and salt lake environments.

Second, the introduction of plastic steel materials

Plastic steel material is a composite material that combines the advantages of steel and plastic, and fuses polymer materials with steel. Plastic steel materials have many advantages such as light weight, safety, durability, heat preservation, corrosion prevention, sound insulation, and the manufacturing cost is lower than the traditional building materials, which greatly reduces the cost.

Advantages of plastic steel materials:

Step 1 Light weight

The density of plastic steel material is very light, so the whole structure is also very light, very suitable for various occasions, such as greening, parks, buildings and so on.

2. Durability

Plastic steel material has excellent durability and corrosion resistance, can withstand high heat, high humidity, high temperature, sunlight ultraviolet, glass and so on.

3. Insulation performance

Plastic steel materials have good insulation properties, can fully prevent the occurrence of electrical short circuit and other problems, so it has a very good advantage in safety.

4. High intensity

Because it is a composite of steel and polymer material fusion, so its strength is very high, can withstand a lot of weight.

Three, aluminum alloy and plastic steel comparison

1. Strength comparison

Aluminum alloy material is stronger than plastic steel material. The specific strength of aluminum alloy is better than that of plastic steel, which means that under the same weight or material dosage, the strength of aluminum alloy is higher than that of plastic steel.

2. Price comparison

The price of aluminum alloy is higher than that of plastic steel. Although it is stronger than plastic steel, the manufacturing cost is higher, so the price is higher. The manufacturing cost of plastic steel is very low, and the price is cheaper than aluminum alloy.

3. Weight comparison

The density of aluminum alloy is 2.7g/cm³, which is about twice that of plastic steel. Therefore, the weight of aluminum alloy is higher than that of plastic steel.

4. Comparison of the scope of use

The application range of aluminum alloy materials is wider than that of plastic steel. Aluminum alloy is not only used in construction, automobiles, aviation and other fields, but also can be used to manufacture electronic products, furniture, daily necessities and so on. The plastic steel is mainly used in garden, water conservancy, chemical industry, environmental protection and other fields.

In summary, at the same cost, the hollow material of aluminum alloy is stronger than that of plastic steel. Although the price is higher, it has better performance in terms of strength and scope of use, so it is also necessary to choose materials according to its own needs.
