Naval Aluminum: 6061 Aluminum Checker Plate
6061 aluminum diamond plate is a kind of checkered aluminum plate with high hardness. In the T6 temper, the hardness is around 95HB. Its bending performance is not good, but the hardness and strength are good. Since it cannot be bent and is easy to crack, users must pay attention to whether there is any bending in the processing process when choosing 6061 aluminum tread plate.
6061 aluminum plate belongs to heat-treatable aluminum alloy plate. It can be processed into T4, T5, and T6 hardness states after aging heat treatment. After aging treatment, the hardness can be increased to above 95-100HB.
What is 6061 T6 aluminium plate? T6 is solid solution treatment plus complete artificial aging. Basically, it is a way to reduce the temperature of the aluminum plate to a certain temperature and quickly cool it in water to increase the hardness of the aluminum plate. Therefore, the 6061T6 aluminum plate has a high tensile strength in performance, greater than or equal to 290, the elongation after fracture shows an increasing trend with the increase of thickness, the yield strength is not less than 240, and the HV hardness is above 95 degrees.
As a quenched aluminum plate, 6061T6 aluminum plate has its specific processes such as rolling, quenching, sawing, aging and so on. The purpose of the process is to improve the performance and strength of the aluminum plate 6061T6 aluminum plate has played a huge practical value in traditional aspects such as mold manufacturing and ship deck.
After heat treatment and pre-stretching process, the strength of 6061 aluminum plate cannot be compared with that of 2xxx series or 7xxx series, but it has many good properties including good processing performance, excellent welding performance, strong electroplating, corrosion resistance, high toughness, no deformation after processing, dense material without defects, easy polishing, easy coloring and excellent anodizing effect.
The production process of 6061 checker aluminum plate has semi-continuous ingot casting, homogenization, sawing, milling,heating, hot rolling, annealing, cold rolling, annealing, cold rolling, solution treatment, aging treatment, embossing, shearing,etc.
The three key indicators of 6061 aluminum plate need to be accurately tested. First, the structure is small and the performance is uniform. Especially for ultra-thick plates, the performance in the thickness direction is required to be uniform, and there should be no large performance fluctuations. For medium-thick plates and thin plates, there should be no large performance fluctuations in length and width.
The second is high dimensional accuracy. It mainly includes accurate thickness and accurate width, especially the most difficult and strict thickness accuracy, which will directly affect the performance and subsequent processing; the third is that the shape of the naval checkered aluminum plate is good. Plate shape includes flatness and plate convexity. Because the two have a great influence on subsequent processing and are irreversible.
