Aluminum has achieved remarkable results
Yuefeng Aluminum Materials Testing Center has successfully passed the review and been awarded the title of "Key Laboratory of Advanced Manufacturing and Surface Treatment Technology for Aluminum Alloys in Wuxi City".
Honor is crowned as a testament to strength
On July 15th, the Science and Technology Bureau of Wuxi City announced the notice on the recognition (construction) of Wuxi's scientific and technological innovation platforms for the year 2025, recognizing the advanced manufacturing and surface treatment technology of aluminum alloys of Yuefeng Aluminum Industry Co., Ltd. as a key laboratory of Wuxi City
Behind this lies years of dedicated research and extensive resource investment in detection technology. Since its establishment, the center has been committed to building an industry-leading detection platform and continuously introducing advanced international detection equipment
An elite team composed of senior material experts and professional testing technicians has been formed. These professionals, with their solid professional knowledge and rich practical experience, have been continuously delving into the field of aluminum alloy material testing, providing a solid technical guarantee for the development of the center
Chemical property testing
Chemical property testing is a fundamental step in the quality control of aluminum materials. In-depth analysis of the chemical composition, structure and content of aluminum materials provides key basis for subsequent processing and application. At the Yuefeng Aluminum Materials Testing Center, advanced chemical analysis and testing technologies are widely applied
The main alloying elements of aluminium alloys include silicon (Si), magnesium (Mg), copper (Cu), zinc (Zn), and manganese (Mn), etc. The secondary alloying elements include nickel (Ni), iron (Fe), titanium (Ti), chromium (Cr), etc. These elements play different roles in aluminium alloys
Therefore, the acceptance inspection of aluminum ingots upon their entry into the factory is one of the important testing methods to ensure product quality. The test results are compared with the limit values in the standards to confirm whether each element is within the allowable deviation range. For example, if a certain grade of aluminum ingot requires Al≥99.70% and the measured value is 99.6%, it is judged as unqualified. If other impurity metals exceed the limit, it is also judged as unqualified
Mechanical property testing
The mechanical properties are the key performance indicators for aluminum materials to withstand various external forces in practical applications. In the construction field, aluminum alloy materials are widely used in structural components such as doors, Windows, frames, and curtain walls. These components have strict requirements for the durability and safety of the materials
Tensile tests are conducted to examine the mechanical properties of aluminum alloy materials, ensuring that they can withstand various natural and human factors such as wind loads and earthquakes during long-term use
Tensile strength reflects the ultimate load-bearing capacity of the material, providing a safety boundary for engineering design
Yield strength is the stress point at which a material begins to undergo plastic deformation. Once the stress exceeds the yield strength, the material will undergo permanent deformation and cannot return to its original state
The elongation after fracture reflects the high ductility of the material. High ductility means that the material can disperse stress through deformation (such as impact absorption), reducing the risk of brittle fracture
Although hardness testing is not part of tensile testing, it is very useful in the initial material screening or quality control
Coating performance testing
In modern aluminum applications, coatings play a crucial role in protecting the surface of aluminum materials, enhancing their decorative and durable properties
The performance of the film layer 1: Sealing quality is directly related to the corrosion resistance, service life and appearance quality of aluminum materials
The performance of the film layer 2: Film thickness. It is like a precise scale, directly affecting the protective ability, mechanical properties and usage effect of aluminum materials
A variety of professional equipment is adopted in the detection technology and instruments to ensure the detection accuracy. Among them, the film gauge (i.e., film thickness gauge) is one of the core tools for detection. It can quickly measure the thickness of the film layer on the surface of aluminum materials. By testing the film gauge on a standard thickness sheet, the measurement error of the film gauge can be controlled within a very small range, providing an accurate and reliable reference for subsequent actual detection
The 3-grid test for film performance is used to evaluate the adhesion of surface coatings (such as electrophoretic or fluorocarbon paint films, powder coatings). By scratching the coating to form a grid, it is observed whether the coating peels off or peels off, thereby determining the bonding strength between the coating and the substrate
Yuefeng Aluminum Materials Testing Center has been awarded the title of "Key Laboratory of Advanced Manufacturing and Surface Treatment Technology for Aluminum Alloys in Wuxi City" this time. The title is the result of its continuous innovation and efforts in the field of aluminum material testing. Through precise chemical property testing, comprehensive mechanical property testing, and strict coating performance testing, Yuefeng Aluminum Materials provides solid quality assurance for each product, constantly promoting the aluminum alloy industry to develop towards higher quality and more advanced directions. It is believed that under the inspiration of this honor, Yuefeng Aluminum Materials will continue to lead the industry trend for a wide range of people Major clients bring more high-quality and reliable aluminum products
