Aluminum alloy window is mainly made of aluminum alloy, which is easier to process than aluminum alloy and steel window.
When consumers choose aluminum alloy window, how to judge the pros and cons of the product? In order to facilitate you to choose the product with good quality and suitable price, you can refer to some methods listed below.
1. Look at the material
The main materials for aluminum alloy windows generally include three aspects: aluminum profiles, glass and hardware. The wall thickness of aluminum profiles used for high-quality aluminum alloy windows should be no less than 1.4mm, and the thickness of oxide film should be 10 μ m; tempered glass (the entry "tempered glass" is provided by industry Encyclopedia) is better than ordinary glass; Stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum parts.
2. Look at processing
High quality aluminum alloy window, fine processing, smooth tangent, consistent angle (the main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear obvious gap, good sealing performance, smooth switch. Poor quality aluminum alloy window, especially aluminum alloy outdoor window products, if the processing is not qualified, there will be sealing property problems, not only air and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off.
3. Look at the appearance
There should be no obvious defects and scratches on the surface of the windows. There should be no obvious color difference on the colored surface of adjacent components on the window. There should be no aluminum chips, burrs, oil spots or other stains on the window surface, and there should be no adhesive overflow at the assembly joint.

The performance of aluminum alloy window usually needs to consider the following aspects: strength, reflected in the selection of aluminum alloy window profile material, whether it can withstand ultra-high pressure; air tightness, mainly reflected in the window structure, whether the inner and outer frame structure of the window is tight; water tightness, mainly to check whether there is water accumulation and leakage phenomenon in the aluminum alloy window; Sound insulation, which mainly depends on the sound insulation effect of insulating glass and the durability of other window accessories such as opening and closing force, opening and closing durability, etc.
5. Look at the price
In general, the price of high-quality aluminum alloy window is 30% higher than that of inferior aluminum alloy window products. The aluminum profile extruded from recycled aluminum containing a lot of impurities is usually used for inferior aluminum alloy window. Some wall thickness of aluminum profile used is not up to standard. Both tensile strength and yield are greatly lower than relevant national regulations. This kind of aluminum alloy window, especially aluminum alloy outdoor window, is very unsafe In order to purchase, do not seek temporary cheap and despise the personal safety of yourself and others.
