Which is better, cast aluminum explosion-proof door or copper door?

2025-03-17

With the rapid development of the building materials industry, the door and window industry also ushered in the spring of development, a hundred schools of thought contend, a hundred flowers bloom. There are various processes and materials of products, followed by everyone's questions about various products, such as: which material is better? Which process is best? Here, from a professional point of view for you to list an example: cast aluminum explosion-proof doors and copper doors which is better?
It is important to point out that none is better, only one is more suited to your individual needs. First of all, let's start with the copper door:

The advantage of copper door is the appearance of the atmosphere, the material is widely known, people's cognition of copper is in a long and shallow stage, because the second-hand recycling market copper purchase price is relatively higher than aluminum a grade, so people subconsciously feel that copper is higher than aluminum. In the practical application of metal materials, it is not the high price of raw materials that the value is higher. In the design and production process of the villa gate, the application of copper is relatively limited, because of the price of raw materials, the production process of the copper door has to take a layer of copper and steel frame structure, so the actual amount of copper is not much, in addition, there are many kinds of copper, such as: red copper, white copper, brass, copper, pure copper, miscellaneous copper and so on. The first few types of copper are basically used in the processing of aerospace or precision parts, while miscellaneous copper is generally used in the production of doors, the main reason is that the raw material price of miscellaneous copper is low, the processing cost is low, the result is that the product will basically appear black spots within half a year after installation, green copper rust, and so on. These are because more copper impurities accelerate the oxidation of copper with carbon dioxide in the air, acid rain and other active gases in the air to form a reactant.

The most important point: copper rust is divided into two kinds of harmless rust and harmful rust. The surface of the bronze gradually changes due to the erosion of the soil and the atmosphere, which form a protective layer on the surface of the bronze to prevent further corrosion. This is commonly known as "harmless rust". Harmful bronze rust, like green powder, is very harmful, commonly known as "bronze disease", that is, harmful rust. CuCO3.Cu(OH)2 has a molecular weight of 221.12. Green powder crystal. Relative density 3.8525, refractive index 1.655, 1.875, 1.909, decomposition when heated to 220℃. Insoluble in water and ethanol, soluble in ammonia to form copper divalent ammonia complex. Dissolved in acid to form the corresponding copper salt, dissolved in aqueous solutions of cyanide, ammonia, ammonium salt and alkali metal carbonate, to form copper oxides.

Just imagine, after you spend tens of thousands of dollars, less than half a year to get such a "shabby" door your heart will think? Anyway, I am not willing to, in such a case, you have to choose maintenance, and there are only two ways to remove the rust of the copper door: one is chemical rust, using strong acid to wash off the embroidery, the second is physical rust, using a steel brush or sandpaper to polish off the copper rust. But the above two ways, no matter which, will cause appearance damage to our copper door cost, and the rust removal cycle is about half a year!

The characteristics of cast aluminum explosion-proof door
1. High strength and durability
Cast aluminum explosion doors are usually made of A356 aluminum-copper alloy, which has high strength and toughness and can effectively withstand impact forces. The minimum thickness of the door panel can reach 6mm, and even some high-end products can reach 10mm, ensuring extremely high explosion-proof and impact resistance. In addition, the cast aluminum material is specially treated and has the characteristics of corrosion resistance and fading resistance, which can maintain a long service life even in wet or polluted environments.
2. Exquisite design
The design of cast aluminum explosion-proof door integrates the essence of Chinese and Western culture, novel style, elegant and chic, suitable for a variety of architectural styles. Its surface is treated by electrostatic powder spraying or fluorocarbon paint, which not only has bright color and high gloss, but also can effectively resist ultraviolet and chemical corrosion. In addition, the manufacturing process of the cast aluminum door is exquisite, the whole casting molding is used, there are no welding points, the overall sense is strong, and the appearance is more exquisite.
3. Good sealing and sound insulation performance
The cast aluminum explosion-proof doors are usually equipped with advanced airtight strips around them, which have excellent sealing performance and can effectively isolate external noise and dust. This design not only improves the comfort of living, but also enhances the insulation performance of the door, which helps to save energy and reduce emissions.
4. High-end hardware Accessories
The hardware accessories of cast aluminum explosion-proof doors are also carefully designed and manufactured. For example, its hinge adopts a patented design, a single load-bearing capacity of more than 300kg, even if the weight of the door body exceeds 200kg, it can be guaranteed to open and close freely. In addition, some products are also equipped with gold-plated riot plugs to further enhance safety.
