With the large-scale application and popularization of industrial aluminum, lightweight and strong load-bearing industrial aluminum materials have received praise. However, during use, some aluminum materials have cracks on the surface. Why is this?
With the large-scale application and popularization of industrial aluminum, lightweight and strong load-bearing industrial aluminum materials have received praise. However, during use, some aluminum materials have cracks on the surface. Why is this? Cracks appear in industrial aluminum profiles? What are the reasons for that?
Firstly, if the aluminum extrusion temperature is too high, the tensile strength of the metal surface will decrease, and the frictional force will cause cracking and cracking.
Secondly, due to friction, the metal surface will be subjected to additional tensile stress. When the tensile stress is greater than the tensile strength of the surface metal during use, cracks will occur.
Thirdly, when the aluminum extrusion speed is too fast, the tensile stress applied to the metal surface increases, and cracks appear in the aluminum profile.
Here is a brief introduction to the cracking of industrial aluminum profiles? What are the reasons for this. In fact, in order to strictly control the extrusion process parameters of aluminum profiles to ensure reasonable export speed and temperature, the aluminum extrusion process parameters are strictly controlled.

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.
