Many consumers don't know when buying aluminum doors and windows. In fact, aluminum alloy is divided into primary aluminum and recycled aluminum. Do you know the difference between them? What are the differences between primary aluminum and recycled aluminum?
The choice of doors and windows is very important for house decoration. Doors and windows have the functions of heat preservation, heat insulation, sound insulation, waterproof, fire prevention and so on, which is a necessary process for decoration in every family. Aluminum alloy doors and windows, which are very popular in recent years, have better quality than ordinary doors and windows. Of course, the cost is relatively expensive. Aluminum alloy doors and windows are not only light in material density, beautiful in appearance, but also moisture-proof and anti-corrosion, good sealing performance is favored by many consumers. However, many consumers do not know that aluminum alloy is divided into primary aluminum and recycled aluminum when purchasing aluminum doors and windows. Do you know the difference between them? What are the differences between primary aluminum and recycled aluminum?

differences between primary aluminum and recycled aluminum
1. Recycled aluminum alloy is an aluminum alloy or aluminum metal extracted from aluminum waste alloy materials and waste aluminum or aluminum-containing waste materials after remelting, which is an important source of metallic aluminium. Primary aluminum is pure aluminum extracted from aluminum ore through electrolytic cell. Compared with recycled aluminum, it has stronger strength, hardness, toughness, oxidation resistance and longer service life.

2. Primary aluminum and recycled aluminum products are all kinds of standard or non-standard aluminum alloy ingots. The difference is mainly that the materials are different. The raw aluminum material is bauxite, while the recycled aluminum material includes leftover material, wastes and chips occurring in the production and processing of various aluminum materials, and aluminum wastes occurring after the aluminum-containing products are abolished, such as old aluminum doors and windows.
3. The cross section gloss of recycled aluminum and primary aluminum is different. Primary Aluminum looks at the light from the cross section, which is the Diamond Light and a little bluish. There is no gloss on the cross section of recycled aluminum.
Under the concept of environmental protection and renewable resources advocated by the state, more and more aluminum development enterprises have invested in the recycling and refining process of secondary recycled aluminum. Compared with other metals, aluminum has the highest recyclability, the regeneration benefit is the largest.
Whether it is primary aluminum or recycled aluminum, there is no problem with the quality of doors and windows, or the country will not encourage the recycling of aluminum profiles. If you want to know more, please continue this site.
