It is made by spraying colored paint on the surface of aluminum plate and drying it. The color distribution of the good sprayed board is even, and the color of the poor board will be corrugated when viewed from the side.
Compared with aluminum die casting, magnesium die casting production has a higher residual scrap rate (compared to aluminum die casting scrap output rate).
Die casting production efficiency is 25% higher than aluminum, metal mold casting is 300-500K higher than aluminum, and lost foam casting is 200% higher than aluminum
The chemical conversion of aluminum and aluminum alloys is formed by the direct reaction of the aluminum surface with the chemical oxidant in the solution.
Aluminum plate refers to a rectangular aluminum sheet made of pure aluminum or aluminum alloy material by pressure processing (shearing or sawing) to obtain a rectangular cross section and uniform thickness.
Due to its excellent performance, aluminum is widely used in various industries of the national economy and defense industry. Aluminum is a light-weight structural material with light weight and high strength.
The main application form of aluminum is aluminum alloy rather than pure aluminum metal. This is because when aluminum is formulated as an aluminum alloy, its performance can be significantly improved, such as increased strength and corrosion resistance.
The main ingredients are SCaOMgOK2ONa2OCO2MnO2 organic matter, carbon, etc., and the trace ingredients are GaGeNbTaPCoZrVPCrNi.
The density of aluminum industry and the density of structural aluminum is 2.7, which is about 1/3 of that of general metals, and the conductivity of commonly used aluminum wires is about 61% of copper, and the thermal conductivity is half of silver.
Aluminum is a light metal, and its compounds are widely distributed in nature. Aluminum is second only to oxygen and silicon in the earth's crust.
Chemical cleaning is to use alkali or acid to clean the surface of the workpiece. This method can remove both the oxide film and the oil stain.
The surface of the alumina film is easy to absorb moisture. When welding, it hinders the fusion of the basic metal and easily forms pores, slag, Defects such as no fusion cause the weld performance to deteriorate.
