How can I Buy high quality aluminium 6061 sheets

2019-07-03

Aluminium 6061 sheets have low density, good corrosion resistance, and excellent properties such as excellent plasticity and easy recycling. Aluminum has become the material of choice for lightweighting new energy vehicles. 6061 alloy aluminum plate sheet is often used in new energy vehicles. What are the characteristics of aluminum 6061 plate, and how to choose high quality 6061 alloy aluminum plate?

6061 aluminium sheet has excellent processing properties, good corrosion resistance, high toughness and no deformation after processing, easy color film and excellent oxidation effect. The difference between the state of T6 and T651 of 6061 aluminum sheet is that under normal circumstances, the internal stress of T6 will be relatively large, and the processing will be deformed. The most suitable state for processing should be T651, it is stretched on the basis of T6 to eliminate internal stress.

When we are looking for aluminium 6061 sheets suppliers on the market, there are some tips to judge the product quality.
1, to see if the aluminum sheet 6061 has obvious distortion, whether the surface is smooth and flat, whether there are cracks or bubbles, scratches, burrs, if it is found, it is best not to buy.
2, it is necessary to carefully check whether the surface of the aluminum plate 6061 has different shades of color, and the color difference means that the quality is not enough. Of course, it is also possible to put together the same type of plates for comparison. Of course, if the color difference is too obvious, it is best not to buy. Check that the section thickness of the alloy aluminum plate is the same as that of the marked model.
3, you can use a smooth hard object to scratch the surface of the aluminium sheet 6061, leaving a white scratch, gently wiped by hand and observed, if it cannot be wiped off, the material may have quality problems, but the opposite If it can be easily wiped off, the thickness of the oxide film on the surface of the aluminium sheets is acceptable.
