Features of aluminum checker plate truck tool box

An aluminum checker plate truck tool box is popular because aluminum is a silvery white light metal with good plasticity, high electrical and thermal conductivity, and resistance to oxidation and corrosion. Aluminum alloy is made of pure aluminum added with some alloying elements, such as aluminum-copper alloy, aluminum-zinc-magnesium-copper super hard aluminum alloy and so on. The aluminum alloy has the characteristics of light weight, low cost, and mechanical (evenness), and the aluminum alloy is easy to process and has high heat dissipation. In particular, aluminum checker plates serve as a suitable material for vehicle engine parts. As for most of computer cases, aluminum-copper alloy is used because of its excellent heat dissipation. Because of the combination of copper and aluminum, the heat dissipation performance is quite good, even some high-end CPU water-cooled fans use this material.

A aluminum checker plate truck tool box is different from other profile boxes. It has the characteristics of aluminum alloy material, light weight, easy processing, strong load-bearing capacity, beautiful appearance and reasonable design structure. Due to the unique characteristics of the aluminum checker plate box, the technology content is getting higher and higher, which has a better protection effect on the transportation and use of the product. It is an ideal box for various high-end products.

However, aluminum alloys are extremely oxidizable. In air, aluminum is easily oxidized to form a dense film of Al2O3 (thickness of about 0.1-0.2 μm) with a high melting point (about 2050 ° C), far exceeding the melting point of aluminum and aluminum alloy (about 600). °C or so). The density of alumina is 3.95-4.10g/cm3, which is about 1.4 times that of aluminum. The surface of the alumina film is easy to adsorb moisture. When welding, it hinders the fusion of the basic metal, and it is easy to form pores and slag. Defects such as unfusion cause a drop in weld performance. Therefore, aluminium plates should be fully cleaned before being made into an aluminum checker plate truck tool box.
