Who knows the types and characteristics of metal decorative materials in decorative materials?

Metal materials are divided into two categories: ferrous metals and non-ferrous metals.

Ferrous metals include cast iron, steel, steel is mainly for housing, bridges and other structural materials, only steel stainless steel for decorative use, non-ferrous metals include aluminum and its alloys, copper and copper alloys: gold, silver, etc., which are widely used in architectural decoration.

To a variety of metals as building decoration materials, has a long history, and still leaves many traces, such as the Summer Palace in the copper pavilion, the top of Mount Tai copper temple, Kunming's Golden Temple, Tibet's Potala Palace of gold and blue decorations and so on are all the ancient people left behind the model.

Modern metal decorative materials used in buildings is more diverse, colorful. This is because the metal material has a unique luster and color t as a building decoration materials, metal solemn and noble, durable, are better than other types of building decoration materials.

Modern commonly used metal decorative materials include aluminum and aluminum alloy, stainless steel, copper and copper alloy.

Types and characteristics of decorative metal materials

Types of metal materials used for decoration include aluminum and aluminum alloys, stainless steel, copper and copper alloys.

(1) Characteristics of Aluminum, Aluminum Alloy and its Decorative Products

Aluminum is a light metal among the non-ferrous metals, with a density of 2.7g/m*m and a silvery white color. Aluminum's electrical and thermal conductivity are very good, chemical properties are also very active, exposed to the air, the surface is easy to generate a layer of alumina film, to protect the following metal is no longer subject to corrosion, so the aluminum in the atmosphere corrosion resistance is strong, but because of the film is extremely thin, and thus its corrosion resistance has a certain limit. Pure aluminum has good plasticity, can be made into tubes, bars, plates, etc.. However, the strength and hardness of aluminum is low. Aluminum's polished surface of white light reflectivity of more than 80%, the ultraviolet, infrared also has a strong reflective ability. Aluminum can also be surface coloring, so as to obtain a good decorative effect.

Aluminum alloy is in order to improve the practical value of aluminum, adding magnesium, manganese, copper, zinc, silicon and other elements in the pot and composition. There are many types of aluminum alloy, aluminum alloy used for architectural decoration is a deformed aluminum alloy in the wrought aluminum alloy (referred to as wrought aluminum, code LD). Wrought aluminum alloy is aluminum-magnesium-silicon alloy (AI-Mg-St alloy), of which LD31 has medium strength, high impact toughness, excellent thermoplasticity, can be extruded into a complex structure at high speed, thin-walled, hollow various profiles or forging into a complex structure of forgings. LD31 has excellent welding performance and corrosion resistance, and the surface is very clean and easy to be colored after processing, which is the most widely used alloy species in AI-Mg-St system. Aluminum alloy decorative products include: aluminum alloy doors and windows, aluminum alloy blinds, aluminum alloy decorative panels, aluminum foil, magnesium-aluminum decorative panels, magnesium-aluminum curved panels, aluminum alloy ceiling materials, aluminum alloy balustrades, handrails, screens, gratings and so on. Aluminum foil is a sheet product made of pure aluminum or pouch alloy processed into 6.3pm to 0.2mm. Aluminum foil has good moisture-proof performance and heat insulation performance, so aluminum foil is widely used in the construction industry as a new multifunctional heat insulation and moisture-proof material; for example, aluminum foil in coils can be used as heat insulation curtains, and aluminum foil in sheets (e.g., aluminum foil wave plate, aluminum foil foam board, etc.) is commonly used indoors, which can play a very good decorative role at the same time by choosing the appropriate color pattern.

(2) Stainless steel architectural decorative products

Stainless steel is more than 12% chromium, corrosion-resistant iron-based alloys. Stainless steel can be divided into two kinds of stainless steel and stainless steel, can resist atmospheric corrosion of steel called stainless just, and in some chemical media (such as acids) can resist corrosion of steel for acid-resistant steel. Usually these two types of steel collectively referred to as stainless steel. Used for decorative stainless steel is mainly plate, stainless steel plate is with the help of stainless steel plate surface features to achieve decorative purposes, such as surface smoothness and gloss. Can also be processed through the surface coloring, the production of brown, blue, yellow, red, green and other kinds of colored stainless steel, both to maintain the original excellent corrosion resistance of stainless steel, but also to further improve its decorative effect.

(3) light steel keel

Light steel keel is the skeleton of the installation of a variety of cover panels, is a replacement for wood keel products. Light steel keel with different materials, different colors of the cover panel, not only improves the thermal and acoustic properties of the building, but also directly create a different decorative art and style, is an important element of interior design must be considered. Light steel keel from the material points of aluminum alloy keel, aluminum keel, galvanized steel keel. And thin-walled cold-rolled annealed coil keel. From the cross-section of V-type keel, C-type keel and L-type keel. From the use of the ceiling keel (code D), partition (wall) keel (code Q). Ceiling keel has the main keel (big keel), secondary keel (in the keel and small keel). The main keel is also called the load-bearing keel, and the secondary keel is also called the cladding keel. Partition keel has vertical keel, horizontal keel and through the keel points. Aluminum alloy keel is made into T-type, T-type keel is mainly used for ceiling. All kinds of light steel sheet more made into V-type keel and C-type keel, they can be used in the ceiling and partition.

(4) other metal materials

Copper and copper alloy: pure copper is a purple-red heavy metal, also known as copper. The alloy of copper and zinc is called brass. Its color with the increase in the amount of zinc from yellow-red to yellowish, its mechanical properties than pure copper, lower than the price of pure copper, but also not easy to rust, easy to process into a variety of architectural hardware, building accessories.

Copper and copper alloy decorative products are: copper plate, brass thin-walled tube, brass plate, copper pipe, copper rod, brass tube and so on. They can be used for column surface, wall decoration, can also be made into railings, handrails and other decorative accessories.

Gold foil: is made of gold as a pigment and a very thin finish material, the thickness is only 0.lpm or so. At present, more national key cultural relics and high-level buildings are partially decorated with gold foil to be touched up. Gold signboard: it is a kind of innovation in the application of gold foil, which is incomparable to the signboard made of other materials, luxurious and precious, never fading, and can be maintained for more than 20 years. It is more expensive than the general copper signboard about twice as expensive, but the appearance of color and luster, the use of years are significantly better than the copper signboard
