With the improvement of people's living standards, the increasing improvement and richness of material conditions, and the increasing emphasis and diversity of indoor decoration, various bottled flowers have entered homes and meeting places, becoming indispensable embellishments. Chinese vases have always been made of porcelain. Although they are bright and clean, they are dense, heavy, and easily broken. Some porcelain vases have lead on their surface glaze, which can enter the human body in small amounts over time, which is harmful to the body.

West Aluminum - West Aluminum Industry Telecom: With the improvement of people's living standards, the increasing improvement and richness of material conditions, and the increasing emphasis and diversity of indoor decoration, various bottled flowers have entered homes and meeting places, becoming indispensable embellishments. Chinese vases have always been made of porcelain. Although they are bright and clean, they are dense, heavy, and easily broken. Some porcelain vases have lead on their surface glaze, which can enter the human body in small amounts over time, which is harmful to the body.

So, what material is good for making vases? Use aluminum or aluminum alloy. Japan is one of the earliest countries in the world to use aluminum vases. What are the advantages of aluminum vases? Aluminum is a superior material for making indoor vases. Aluminum is the main group element in the third cycle of the periodic table, with a face centered cubic lattice, multiple slip surfaces, and good plasticity. It can be processed into semi-finished products with various shapes and colors, such as thin and micrometer sized foil, which is thinner than cicada wings; Extruded profiles and forgings with complex cross-sections, and thin and large pipes. Aluminum has no allotropic transformation, atomic number 13, and relative atomic mass 26.9815.

Aluminum has a low density of 2.70g/cm3, which is about one-third of that of copper and steel. Holding a moderate vase in your hand will not weigh heavily; Aluminum has high corrosion resistance and a bright silver white color. Even if left in the air for many years, it will not change its true color; Aluminum has excellent anodic oxidation performance, and its membrane is of microporous structure, which can be coated with various colors; Good thermal conductivity and conductivity. The conductivity of industrial pure aluminum in the O state is 59% IACS, and the thermal conductivity at 25 ℃ is 222.6W/(m · k); Linear expansion coefficient of 23.5 at (20~100) ℃ μ m/(m·k); Elastic modulus 70KN/mm2, shear modulus 26.25KN/mm2; The sound propagation speed is about 4900m/s; Electrical resistivity of industrial pure aluminum in state O at 20 ℃ 0.02922 μ M · m, resistance temperature coefficient 0.1 μ Ω· m/k, volume magnetic susceptibility 6.26 × 10-7, input=2500 × The reflectivity of 10-10m light is 87%, the refractive index of white light (independent of the material surface state) is 0.78-1.48, and the absorption index of white light (independent of the material surface state) is 2.85-3.92.

Aluminum has good radiation resistance, excellent casting performance, weldability, and impact resistance, as well as good riveting and adhesive properties. Until today, no evidence has been found that aluminum is harmful to living organisms, but aluminum has not been found to be an essential trace element for the human body. It can only be said that aluminum is a neutral element for the human body. Aluminum resources are extremely abundant, accounting for approximately 7.8% of the Earth's crust mass.
