6061 aluminum diamond plate is a type of checkered aluminum plate with excellent hardness. The T6 temper has a hardness of approximately 95HB. It has poor bending performance, yet it is hard and strong. Because it cannot be bent and is easily cracked, users must consider whether there is any bending during the manufacturing process when selecting 6061 T6 aluminum tread plate.
6061 aluminum plate is a heat-treatable aluminum alloy plate. After age, it can be heat treated to achieve T4, T5, and T6 hardness levels. After age, the hardness can be enhanced above 95-100HB.
What is a 6061 T6 aluminum plate? T6 combines solid solution treatment with total artificial aging. Essentially, it is a method of reducing the temperature of an aluminum plate to a specific level and quickly cooling it in water to increase its hardness. As a result, the 6061T6 aluminum plate has a high tensile strength in performance, greater than or equal to 290, rising elongation after fracture with thickness, a yield strength of at least 240, and an HV hardness greater than 95 degrees.
As a quenched aluminum plate, 6061 T6 aluminum plate undergoes particular operations such as rolling, quenching, cutting, and aging. The process aims to improve the performance and strength of the aluminum plate. 6061T6 aluminum plate has a high practical value in classic applications like mold making and ship decking.
After heat treatment and pre-stretching, the strength of 6061 aluminum plate cannot be compared to that of the 2xxx or 7xxx series, but it has many good properties such as 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 manufacturing process for 6061 T6 checker aluminum plate includes semi-continuous ingot casting, homogenization, sawing, milling, heating, hot rolling, annealing, cold rolling, annealing, cold rolling, solution treatment, aging treatment, embossing, shearing, and so on.
