Metal photo frame:
Generally, the metal frame is used, and the color is gorgeous. And the color of the metal looks good and durable. Beautiful and atmospheric, not easy to wear. Imported materials, healthy and durable photo frames.
The metal has physical properties such as electrical conductivity, thermal conductivity, high hardness, high strength, high density, high melting point, good metallic luster, etc. At the same time, the metal is chemically active, and most metals can react with oxygen, acid solution, and salt solution.
It is worth emphasizing that some metals have special physical properties, such as: the melting point of tungsten is extremely high, the conductivity of copper is good, the ductility of gold is good, the ductility of platinum is good, and the mercury at normal temperature is liquid. In addition, the alloy has better corrosion resistance, hardness and strength, and lower melting point than metals.
