In modern industry, due to the characteristics of aluminum and aluminum alloy materials, their applications in aviation, machinery, automobiles, ships, and electronics industries are very extensive. In industrial production, aluminum and aluminum alloys need to undergo a series of processing and surface treatment in order to be made into the final product. During the processing, aluminum and its alloys undergo surface cleaning, storage, and metal casting processes, which may result in localized blackening and corrosion. What is the reason for local black spots on the surface of aluminum and aluminum alloys? 1.Using corrosive cleaning agents During the surface treatment process of aluminum and aluminum alloys, highly corrosive industrial cleaning agents are used, causing corrosion to the substrate surface of aluminum and aluminum alloys, resulting in blackening of the aluminum surface. 2.Unreasonable storage environment The storage environment for aluminum and aluminum alloys is unreasonable. Aluminum and aluminum alloys are stored in environments with high temperatures, salinity, and humidity. In such environments, aluminum and aluminum alloys are prone to oxidation and blackening. 3.Inadequate cleaning Inadequate or uncleaned cleaning of aluminum and aluminum alloy surfaces. After die casting and mechanical processing, aluminum and aluminum alloys are not thoroughly cleaned of cutting fluid, release agents, other corrosive components, stains, etc. on the surface of aluminum and aluminum alloys. These components remain on the surface of aluminum and aluminum alloys for a long time, leading to mold spots and localized blackening. 4.Failure to carry out post-processing in a timely manner The treatment process design of aluminum and aluminum alloys is unreasonable. After surface treatment such as cleaning and polishing, aluminum and aluminum alloys are not promptly treated for oxidation, resulting in corrosion, oxidation, and localized blackening of aluminum and aluminum alloys.

Salt spray testing is a common method used to assess the corrosion resistance of materials, including aluminum profiles. During this testing process, the aluminum profiles are exposed to a salty mist environment to simulate corrosive conditions that the profiles may encounter in real-world applications. The main purpose of salt spray testing for aluminum profiles is to evaluate their ability to withstand corrosion, which is a critical factor in determining their durability and longevity. By subjecting the profiles to a controlled salt spray environment for a specified period, manufacturers can assess how well the profiles resist corrosion and identify any potential weaknesses in their protective coatings or surface treatments. Salt spray testing is particularly important for aluminum profiles used in outdoor or marine applications, where they are exposed to harsh environmental conditions, including saltwater and humidity. By conducting this testing, manufacturers can ensure that their aluminum profiles meet industry standards for corrosion resistance and quality, helping to guarantee the performance and lifespan of the products.

1. There are seams or poor welding Hollow aluminum alloy profiles are extruded using a plane shunt combination die. The metal goes through the process of shunting and welding, so there are welding lines in the hollow profiles. If the metal welding is not good and gaps appear, it is a defect. There are two reasons for the gap. One is that the shunt hole and the welding chamber are small, the metal flow is insufficient, and the metal does not form enough hydrostatic pressure in the welding chamber. The product is not welded well and flows out of the die hole, resulting in welding of the product. Gaps; the second is caused by excessive lubrication and poor lubrication causing poor welding of hollow profiles. The former can be solved by grinding or milling to enlarge the shunt hole and the welding chamber area, and increase the metal supply flow, so that the metal can form sufficient hydrostatic pressure in the welding chamber. The latter can be solved by using a non-lubricated extrusion process. 2. The wall of the aluminum alloy profile has a concave or convex arcuate surface. 1）The reason for the concave arcuate surface of the hollow aluminum alloy profile wall: the mold core working belt is lower than the lower mold hole working belt, and the effective length of the mold core working belt is too short. Correction method: Place a spacer ring between the mold core and the lower mold so that the mold core working belt is at the same height as the lower mold hole sizing belt under stress. At the same time, the same thickness is reduced at the outlet of the lower mold. 2）Reasons for the bulging of the hollow aluminum alloy profile wall: the mold has been used for too long, the mold core working belt is severely worn, grooves appear, and the friction resistance is increased. The slow metal flow causes the hollow profile wall to bulge. Correction method: If the profile wall thickness tolerance allows, you can file or polish the surface of the working belt of the mold core to reduce the friction resistance; if the wear of the mold core working belt is serious and the profile wall thickness has reached the upper deviation, the mold can be Preheat to about 300°C, repair weld the mold core shape, then file it to the required size and polish it before use; if the mold core working belt is not worn, file the outer obstruction and the inner stagnation of the mold core working belt. That’s it. 3. Surface stripes on aluminum alloy profiles Stripes appear on the outer surface of extruded profiles, which are more obvious after anodizing. This defect is mostly seen on the parts with large differences in wall thickness of the profile, the welding parts of the metal under the shunt bridge, and the back side with "branches" and threaded holes on the inside. cause: 1）The "branches" and threaded holes on the inside of the profile cause surface streaks due to insufficient or excessive metal supply; 2）Stripes on the profile surface caused by the wel...

T4, T5, and T6 are markers related to the heat treatment state of aluminum alloys, usually used to indicate different hardness and strength. These markings are typically used to describe the state of aluminum alloy materials that have undergone heat treatment. Here are some of their main differences: 1.T4 status: T4 indicates that the aluminum alloy has undergone natural aging. In the T4 state, the aluminum alloy undergoes solid solution treatment and then naturally ages at room temperature for a period of time. This state typically provides moderate hardness and strength, but is not as high as other states. The T4 state is suitable for applications that require a certain level of hardness and strength, but do not require too high performance. 2. T5 status: T5 indicates that the aluminum alloy has undergone artificial aging treatment. In the T5 state, after solid solution treatment, aluminum alloy will undergo artificial aging treatment at a certain temperature to increase its hardness and strength. T5 state typically provides higher hardness and strength than T4, making it suitable for applications that require higher performance. 3. T6 status: T6 indicates that the aluminum alloy has undergone artificial aging treatment and is usually aged at higher temperatures. The T6 state provides the highest hardness and strength, typically used in applications that require high performance and strength. In the T6 state, aluminum alloys typically undergo stricter heat treatment processes to achieve optimal performance. The selection of these states depends on specific engineering requirements and applications, requiring a balance between hardness, strength, and other material properties. Aluminum alloys in different states can be used for different applications to meet specific requirements. Therefore, when selecting the appropriate heat treatment state, it is necessary to consider the final performance requirements of the material.
