High-strength aluminum alloy fasteners play an important role in various mechanical equipment and structures, and play a pivotal role in ensuring the safety and stability of equipment. This paper will deeply explore the manufacturing process and performance optimization of high-strength aluminum alloy fasteners, through understanding its manufacturing process, performance characteristics and how to improve its performance, to further understand the application value and importance of this key technology.

  1. Manufacturing process

The manufacture of high-strength aluminum alloy fasteners requires a series of precise technological processes. First of all, choose the appropriate aluminum alloy material, generally choose aluminum alloy with high strength, wear resistance and corrosion resistance. Next, through processing equipment such as cutting machines, drilling machines, milling machines, etc., for accurate processing and forming. Process parameters, such as temperature, pressure, time, etc. should be strictly controlled during processing to ensure the accuracy and quality of the final product.

Second, performance optimization

Tensile strength: Through the selection of high-strength aluminum alloy materials, optimization of processing technology, the implementation of heat treatment and other methods to improve the tensile strength of fasteners. For example, the use of solution aging treatment can effectively improve the strength and hardness of aluminum alloy.
Fatigue strength: Fatigue strength is a measure of the fastener’s ability to resist damage under alternating loads. The fatigue strength of fasteners can be significantly improved by optimizing structural design, selecting aluminum alloy material with high fatigue strength and implementing surface strengthening treatment.
Corrosion resistance: The selection of aluminum alloy materials with excellent corrosion resistance, optimization of processing technology, coating treatment of the surface of fasteners and other measures to improve the corrosion resistance of fasteners in various environments.

  1. Case analysis

Taking automobile hub screws as an example, the manufacturing process first selects aluminum alloy materials with high strength, wear resistance and corrosion resistance. Through accurate processing equipment for molding processing, and strict control of process parameters. In order to improve the tensile strength, solution aging treatment was used to optimize the properties of aluminum alloy. In order to increase fatigue strength, the structural design is optimized, such as increasing the diameter of the screw and reducing the clearance of the mating surface, thereby improving its resistance to alternating loads. In addition, the screw surface is coated to enhance its corrosion resistance.

The optimization of manufacturing process and performance of high strength aluminum alloy fasteners is of great significance to improve the safety and stability of equipment. Through in-depth understanding of its manufacturing process and performance characteristics, further optimization of manufacturing process and selection of high-strength aluminum alloy materials, while implementing effective heat treatment and surface treatment measures, can effectively improve the performance and quality of fasteners. In the example analysis, taking automobile wheel hub screws as an example, the tensile strength, fatigue strength and corrosion resistance are improved through the manufacturing process and performance optimization, thus extending the service life and enhancing the safety.
