Aluminum, also known as aluminum alloy material, is mainly used in the production of doors and windows. It has the characteristics of beauty, light weight, cold resistance, heat resistance, and easy maintenance. It is currently the most common material used in doors and windows, including spot aluminum for sliding windows and spot aluminum for casement windows. But spot aluminum materials can also be divided into high-quality and low-quality, so it is important to be careful when choosing. Is there any method for identifying the quality of aluminum materials in stock for sliding windows? Let's take a look below!

But spot aluminum materials can also be divided into high-quality and low-quality, so it is important to be careful when choosing. Is there any method for identifying the quality of aluminum materials in stock for sliding windows? Let's take a look below!
The method for identifying the quality of aluminum materials in stock for sliding windows is as follows:
1. Thickness: There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series, and 90 series, among which the series represents the thickness.
2. Strength: The tensile strength should reach 157 Newton per square meter millimeter and the yield strength should reach 108 Newton per square millimeter. When making a purchase, the profile can be moderately bent by hand, and it should be able to return to its original state when released.
3. Chromaticity: The color of the same aluminum alloy profile should be consistent. If there is a significant color difference, it is not suitable to purchase.
4. Flatness: Check the surface of the aluminum alloy profile to ensure there are no dents or bulges.
5. Glossiness: Aluminum alloy doors and windows should avoid selecting profiles with open bubbles (white spots) and ash (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.
6. Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, you can lightly scratch the surface of the profile to see if the oxide film on its surface can be wiped off.

What are the advantages of choosing insulated aluminum alloy profile windows?
What are the advantages of choosing insulated aluminum alloy profile windows? Compared with the standardized aluminum door and window architecture, insulated aluminum alloy profile windows have many advantages. For example, insulated aluminum alloy profiles will be integrated with reinforced acrylic resin rods for thermal insulation and frost resistance. Insulated aluminum alloy profiles and reinforced acrylic resin rods can generate insulation system software to block outdoor heat, cold, and noise. Ensure warmth in winter and coolness in summer, and provide a very comfortable natural environment for building construction.
