Material quality can be understood as material quality, but in aluminum alloy, material mainly refers to the alloy content, that is, 5052 aluminum plate and 5083 aluminum plate, which we often refer to, and the material in the material certificate also includes the factor of mechanical properties. Generally speaking, we can understand material as two parts, The first part is the chemical composition, that is, the alloy content, another kind of timely mechanical properties, including elongation and tensile strength.
In fact, in conventional terms, we usually default that the material only refers to the alloy content, that is, if the material is required to be an alloy brand, the chemical composition must meet the standard of the brand, and the mechanical properties are usually reflected in the state. For example, 5052-H32 will appear in the standard aluminum plate order, in which 5052 refers to the material and H32 refers to the mechanical properties.
How to confirm whether the material is qualified: this can only be confirmed by professional instruments and equipment. In fact, many users will not inspect it, and sellers dare not replace it with other materials, so the material is often guaranteed by integrity, Of course, for orders with strict requirements or large quantities, a third-party testing structure can also be entrusted for material testing.
Aluminum has low melting point and good casting performance. The mechanical properties of aluminum are closely related to its purity. The strength of industrial aluminum plate is low, but the aluminum alloy composed of aluminum and some alloy elements not only maintains the inherent characteristics of aluminum to some extent, but also significantly improves its hardness and strength. When some aluminum alloys are used as structural materials, their strength can exceed that of general structural steel; When some aluminum alloys are used as die materials, their service life can exceed that of general die steel. Aluminum and a variety of aluminum alloys have excellent ductility and can be processed in a variety of plasticity.
The machinability of any kind of aluminum alloy is better than that of steel and pure aluminum, but the machinability of various deformed aluminum alloys and cast alloys can be very different. Aluminum and aluminum alloy are one of the most easily formed metal materials, but the allowable deformation of aluminum alloy is affected by its chemical composition, grade and heat treatment. Because the mechanical strength and work hardening rate of aluminum alloy are low, its formability is different from that of other metals.
The machinery manufacturing industry widely uses aluminum plates to manufacture wheels, pulleys, centrifuges, ventilators, crane and pump parts, pistons and engine cylinders, as well as aluminum plate stamping parts.
This is because the characteristics of aluminum and aluminum alloy not only have low density, but also have the required strength and hardness, which can reduce the energy consumption in mechanical operation, or greatly improve the operation speed under the condition of using the same energy, but also relatively prolong the service life of the parts. At the same time, after the weight and size of the whole machine are reduced, it can be more suitable for production, transportation, installation and operation.
The following industries are mainly used for industrial and transportation equipment, such as aluminum and other durable goods. In the past 20 years, aluminum for construction, automobile and packaging has become the three major uses of aluminum in industrial developed countries.
