Production requirements and process control of 7014 aviation aluminum alloy plate
The AMS-QQ-A-250/13 and DTD 5110 standards specify the production requirements and process control of 7014 aluminum alloy plates. Among them, the following is the basic process for the production of 7014 aluminum alloy plates specified in the standard:
Preparation of aluminum alloy raw materials: firstly, it is necessary to select suitable aluminum alloy raw materials that meet the AMS-QQ-A-250/13 standard, such as 7175, 7075, etc., and process them into aluminum alloy plate raw materials through mixing, casting and other processes.
Heat treatment: after being rolled into plates, heat treatment processes, including solutionization and artificial aging treatment, are required to adjust the structure and properties of the alloy. Among them, solution treatment requires high-temperature heating to uniformly dissolve the elements in the alloy material in the solid solution; artificial aging treatment is to keep the material at a lower temperature for a certain period of time, so that the elements in the solid solution are rearranged and form corresponding strengthening. phase to increase the strength and toughness of the material.
Panel rolling: after heat treatment, the aluminum alloy plate needs to be rolled to make it reach the required size and flatness.
Aluminum cladding: after the rolling process, the aluminum alloy plate needs to be clad with aluminum, that is, a layer of pure aluminum material is pressed to one side of the aluminum alloy plate to improve its surface quality and corrosion resistance.
Machining and surface treatment: finally, machining and surface treatment are required to meet the requirements in the AMS-QQ-A-250/13 standard, such as flatness, surface finish, dimensional accuracy, chemical composition, etc.
It should be noted that the production process of aviation aluminum alloy plates needs to be strictly controlled in every link to ensure that the quality and performance of the products meet the standards and customer requirements. At the same time, the heat treatment process and manufacturing process required for aviation aluminum alloy plates in different tempers may also be different.
When purchasing 7014 aluminum alloy aircraft aluminum plate, you need to pay attention to the following items
Material certification: when purchasing aluminum plates, suppliers are required to provide certification documents that meet aviation standards, such as AMS, DTD, QQ and other certification documents.
Dimensional requirements: according to specific application needs, suppliers are required to provide aluminum plates that meet the specifications, including dimensional parameters such as thickness, width, and length.
Surface treatment: suppliers are required to provide surface treatment that meets the requirements, such as aluminum cladding, anodizing, painting, etc., to meet the use requirements of aircraft parts.
Delivery time requirement: according to the project progress requirements, the supplier is required to provide a satisfactory delivery time to ensure the smooth progress of the aircraft parts production plan.
Quality assurance: suppliers are required to provide quality assurance that meets aviation standards to ensure that the supplied aluminum sheets meet the specifications and have stable quality performance.
Price advantage: on the premise of meeting quality requirements, suppliers are required to provide competitive prices to reduce aircraft production costs.
To sum up, when purchasing 7014 aluminum alloy aircraft aluminum plate, you need to pay attention to material certification, size requirements, surface treatment, delivery time requirements, quality assurance and price advantages, etc., to ensure that the purchased aluminum plate meets the production requirements and has a stable quality performance.
