5×8 aluminum sheet
There are many aluminum sheet manufacturers, and their aluminum sheet plates are also of various kinds, but the quality of aluminum plates is also mixed and uneven. How to choose good quality and cost-effective among many 5×8 aluminum sheet products? Here are a few simple steps:
First, check the outer packaging of the 5×8 aluminum sheet
Good packaging not only shows the strength of aluminum sheet manufacturers, and they are willing to spend a lot of money on product packaging, but also shows that manufacturers pay more attention to product protection. In addition, it also shows that the manufacturer is very effective in the management of aluminum plate production.
Second, check the surface of the 5×8 aluminum sheet
The high-quality 5×8 aluminum sheet has no defects such as roll marks, black spots, scratches, oil spots, corrosion, fission, etc. on the surface; the plate shape is flat without obvious bending; the diagonals of the single aluminum sheet are consistent; the whole aluminum sheet is placed neatly, Each aluminum plate has the same length and width. If the surface of the aluminum plate is covered with a protective film, remove the protective film, at least check the entire width of the plate, to avoid defects being covered. A micrometer can measure the thickness of an aluminum plate
Third，Use tools to measure products
Third, use measuring tools such as a micrometer, meter ruler, and vernier caliper to measure. According to demand, select products provided by aluminum plate manufacturers for evaluation. And choose different measuring tools according to the magnitude of the measured size to measure the thickness, width, length, unevenness, diagonal and other products of the 5×8 aluminum sheet. For the specific size deviation, please refer to GB/T 3880. 1-2006. Choose at least three points for each measurement to measure whether the size of the 5×8 aluminum sheet or the error is uniform and whether it is within the national standard.
Fourth, check the list of 5×8 aluminum sheet products
Good aluminum sheet manufacturers will test the composition and performance of each batch of a 5×8 aluminum sheet. After the aluminum sheet manufacturer provides the material list, check whether the composition and performance of the product corresponding to the material list are controlled within the scope of the national standard. For specific values, please refer to GB/T 3880-2006. And note that the material list must be stamped with the official seal of the manufacturer. If there is a problem during the use of the aluminum sheet, the material list can be used as the basis to test the 5×8 aluminum sheet and raise a quality objection to the manufacturer.
