Model：Super light , Ultra light 5052 aviation grade aluminum alloy, 5052 aluminum plate aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, the magnesium content is between 3-5%. Also known as aluminum magnesium alloy. It is characterized by low density, high tensile strength, and high elongation. In the same area, the weight of aluminum magnesium alloy is lower than other series, so it is often used in aviation, such as aircraft fuel tank. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, belonging to the hot rolling aluminum plate series, so it can do deep oxidation processing. In China, 5052 series aluminum plate belongs to one of the more mature aluminum plate series. Widely used in automobile, ship, aerospace, aviation, electrical, agriculture, electromechanical, home and other industries. The general aluminum alloy for doors and windows is incomparable, and the cost is naturally a little high. This plate is lighter than other plates on the market. The large-scale weight of this plate is about 0.8kg, greatly improving the burden of musicians. The whole plate has no welding points. It adopts the built-in fixation method, which is compression resistant, impact resistant, and enhances the overall performance. It reasonably uses the light and hard aviatio.n grade aluminum alloy. The surface adopts frosted gray paint to be more resistant to impetuosity. Generally, bright paint is easy to be knocked by some sharp objects, leaving traces. This pedalboard is easy for you to be impetuous without worrying about scratches. This bag can be one shoulder back It can be inserted into the pull rod of Luggage Suitcase ，which is convenient to carry and greatly improves the burden of the musicians
