.25 aluminum plate, can also be called 1/4 aluminum plate. Same as the representation method of 1/8 aluminum sheet. The thickness of this series of aluminum plates is 0.25 inches. The alloy is not limited, it can be from 1000 series to 7000 series. Commonly used aluminum plate alloys are 1060 aluminum plate, 1100 aluminum plate, 3003 aluminum plate, 5052 aluminum plate, 6061 aluminum plate. 7075 aluminum plate and 7005 aluminum plate in 7000 series aluminum plate. The 7000 series aluminum plate has high hardness and the price is naturally more expensive, so the 7000 series .25 aluminum plate is not commonly used in life.
3003 .25 aluminum plate has excellent forming characteristics, corrosion resistance, weldability and conductivity. 3003 aluminum sheet has a smooth surface, good plasticity and pressure resistance. In addition, it also has the characteristics of impact resistance, not easy to break and leak. 3003 aluminum plate is also a kind of anti-rust aluminum, so it can be used in humid environments. Concentrated in household appliances such as refrigerators, air conditioners, as well as cold storage, ventilation ducts, and so on. 3003 aluminum sheet is a cost-effective aluminum sheet product, which is often used in industry and other applications that require a large amount of aluminum materials. 3003 aluminum has energy saving, environmental protection, safety performance, waterproof performance and quick and flexible construction.
5052 represents the alloy of the product, .25 represents the thickness of the aluminum plate is 0.25 inches. Starting with 5 means that the product belongs to the aluminum-magnesium alloy product, and then according to the chemical composition, it can be seen that the magnesium alloy content of the product is between 2.2-2.8% and the density is 2.68. Usually the company takes the extreme value in the processing process, which is 2.5% of the magnesium alloy content, so this series of aluminum plates can become almg2.5 again. The 5052H32.25 aluminum plate has been treated, incompletely annealed and hardened, and the hardness is 1/ 4. The hardness of 5052H34 aluminum plate is 1/2.
Mingtai is very precise in production control. The quality inspection requirements are strict to ensure that the products are mature in technology and superior in performance. For example, during quality inspection, three key indicators of .25 aluminum plate were accurately inspected.
First, the organization is small and the performance is uniform. Especially for ultra-thick plates, the performance in the thickness direction is required to be uniform without large performance fluctuations. For medium and thick plates and thin plates, there should be no large performance fluctuations in length and width;
The second is the high requirement for dimensional accuracy. It mainly includes the accuracy of thickness and width. The accuracy of thickness is the most difficult, and the requirements are very strict, which will directly affect the performance and subsequent processing;
The third is that the plate shape is good. The plate shape includes flatness and plate convexity. Because the two have a great influence on subsequent processing, and are irreversible.
