When aluminum sheets are used, the term "Gauge" Is often used. The gauge is used to specify the thickness of the aluminum sheet. There is no standard value in aluminum gauge sheet metal, and at the same time, it is not in the metric system. Not same to 4'x8' aluminum sheet. The gauge value has nothing to do with those measuring systems. The gauge conversion table can be used to determine the actual thickness of the aluminum sheet in inches or millimeters. For example, according to the gauge conversion table, the thickness of 18 gauge aluminum is 0.0403 inches or 1.024 mm. The meter number "18" Has nothing to do with the actual measured value. And there is one more point, different gauge systems, in which specific gauge names are used for specific metal types. For example, the same 18 gauge represents a steel thickness of 0.0478 inches or 1.214 mm.
Aluminum gauge sheet metal is the material of choice in many industries. More and more aluminum sheet manufacturers have emerged on the market, and how to judge the quality has become a problem. Remind you to be cautious when choosing aluminum sheet. Introduce you in detail the skills to distinguish the material of the alloy aluminum sheet.
Many people wonder whether there is credibility to judge the quality of aluminum sheet by curvature.
The alloy aluminum sheet itself cannot be bent, even the aluminum sheet of other materials cannot be bent. In fact, the degree of curvature we are talking about does not depend entirely on the aluminum sheet, but on its material. Because the aluminum profile is not easy to bend, and the surface is smooth and flat, without cracks, scratches and other problems. If these problems occur with the aluminum sheet you purchased, it means that the quality of the aluminum sheet has certain problems.
When choosing aluminum alloy sheet, check its color difference. If the color difference of the aluminum sheet is relatively poor, it means that the quality of the production process is not good enough. I would like to remind you that when comparing, you can compare the same alloy aluminum sheets together, and finally choose the aluminum sheet with a better color. In addition to checking the chromatic aberration, it is also necessary to check whether the thickness of the aluminum sheet is consistent with the marked data.
To judge the quality of the aluminum sheet, you can scratch it with a smooth hard object. Instead of scratching directly on the aluminum sheet, you should know that a protective film will be attached to the surface of the aluminum sheet, so lightly scratch on the protective film. This will leave scratches on the surface. See if it can be wiped off gently with your hands; if it can’t be wiped off, it means that the quality of the material has a certain problem; if the scratches can be wiped off, it means that the thickness of the oxide film on the surface of the aluminum sheet is qualified, so don’t worry about scratching the aluminum sheet. . This method is relatively straightforward and easy to operate.
If the user wants to choose the true quality and reliable aluminum alloy sheet, it is best to choose a reliable aluminum sheet manufacturer to ensure the reliable quality of the alloy aluminum sheet produced. Here we recommend Mingtai Aluminum, which specializes in the production of alloy aluminum sheets, and its rigorous craftsmanship can ensure its reliable quality.
