Aluminum alloy bridge has beautiful appearance, simple structure, unique style, large load capacity, light weight and other characteristics. After anodizing the surface of aluminum alloy cable tray, it is not only anti-corrosion, but also anti-electromagnetic interference, especially anti-shielding interference, which is irreplaceable for steel bridge. Aluminum alloy bridge in modern industry, modern national defense, modern high-tech, has a significant practical value.
Aluminum-based alloy general term. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium and so on.
Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in the industry, the use of second only to steel.
Aluminum alloy is divided into two categories: casting aluminum alloy, used in the cast state; deformed aluminum alloy, can withstand pressure processing, mechanical properties higher than the cast state. Can be processed into a variety of forms, specifications of aluminum alloy material. Aluminum alloy is mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction.
Characteristics and scope of use
Excellent high corrosion resistance, applicable to various fields such as power plant, chemical industry, petrochemical industry, etc., especially suitable for places with highly corrosive environment. Extruded ladder edges and crosspieces make the bridges have a smooth appearance. Reasonable processing technology and connection methods make the bridges easy to install, among which the large-span disc type straight-through can meet the carrying capacity of 6 meters. Aluminum alloy plate bottom plate, according to the need can be used flat plate structure or convex ornamental stamping structure.
Some aluminum alloys can be heat-treated to obtain good mechanical properties, physical properties and corrosion resistance.
Casting aluminum alloy can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-zinc alloy and aluminum-rare-earth alloy according to its chemical composition, of which aluminum-silicon alloy has simple aluminum-silicon alloy (can not be heat-treated to strengthen the mechanical properties of the lower casting performance is good), and special aluminum-silicon alloy (can be strengthened by heat treatment, mechanical properties of the higher casting performance is good).
