Detailed Product Description: | Nanping Aluminum large supply: all kinds of aluminum grade aluminum, aluminum rod, aluminum tube, aluminum, aluminum, aluminum row, and so on. Company keep its quality first, customer first commitment to quality and efficient service standards, and to welcome new and old customers call Advisory extra-thick aluminum 7A52 superhard aluminum 7003 aluminum rod, military, aluminum, imports of South Korean aluminum, SWA super- slabs, imported engine aluminum. Aluminum alloy is the industry's most widely used non-ferrous structural materials have been widely applied in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology in recent years as well as the industrial economy, the increasing demand for aluminum alloy welded structure, so that the welding of aluminum alloys along with in-depth study. Aluminum alloy widely used to promote the development of aluminum alloy welding technology, welding technology development and expansion of the aluminum applications, aluminum welding technology is becoming one of the hotspots. Density of pure aluminum (ρ = 2.7g/cm3), about 1/3 of the iron, the low melting point (660 ° C), aluminum is face centered cubic structure, so a high degree of plasticity (of δ: 32 ~ 40%, ψ: 70 ~ 90%), ease of processing, can be made into various shapes, plates. Good corrosion resistance; but the low strength of pure aluminum, annealed state the σb value of approximately 8kgf/mm2, it is not appropriate for the structural materials. Through long-term production practices and scientific experiments, gradually adding alloying elements and the use of heat treatment to strengthen the aluminum, which has been a series of aluminum alloy. Add certain elements in the formation of alloys with high strength, but also in the same time maintaining the advantages of pure aluminum light weight, etc. the the σb values ??up to 24 ~ 60kgf/mm2. This allows the "strength" (the ratio of the intensity and the proportion of σb / ρ) is better than a lot of alloy steel, an ideal structural material, widely used in machinery manufacturing, transport machinery, power machinery, and aviation industry, aircraft fuselage skin, compressor, often aluminum alloy to reduce weight. The welding of aluminum alloy instead of steel plate material, reduce the structural weight of more than 50%. Low density of aluminum alloy, but the intensity is relatively high, close to or exceed the high quality steel, plastic, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industrial usage after the steel . Aluminum alloy divided into two categories: cast aluminum alloy, cast; wrought aluminum alloy under pressure processing. Can be processed into various forms, specifications of the aluminum alloy material. Mainly used in the manufacture of aviation equipment, building doors and windows. Aluminum alloy processing methods can be divided into the deformation of aluminum and cast aluminum alloy. Deformation of aluminum alloy is divided into non-heat strengthened aluminum alloy and heat treatment strengthened aluminum alloy. Do not heat treatment to strengthen the type can not by heat treatment to improve the mechanical properties can only be achieved by cold deformation strengthening, which includes high purity aluminum, industrial high purity aluminum, industrial pure aluminum and rust-proof aluminum and other. Can be heat-strengthened aluminum alloy by means of quenching and aging heat treatment to improve mechanical properties, it can be divided into hard aluminum, wrought aluminum, super-hard aluminum and special aluminum alloy. Some aluminum alloys can be used to heat treatment to obtain good mechanical properties, physical properties and corrosion resistance. Cast aluminum alloy (not heat treatment to strengthen the chemical composition of Al-Si alloys, aluminum-copper alloy, aluminum-magnesium alloy, aluminum, zinc alloy and aluminum rare earth alloy, Al-Si alloys and simple Al-Si alloys can be divided into low, mechanical properties, casting performance), special-Al-Si alloy (heat strengthened, higher mechanical properties, good casting properties) The pure aluminum sub-smelting products and pressure processed into two categories, the former chemical composition of Al, the latter in pinyin the LV (aluminum, for industrial use) that. Aircraft A variety of aircraft aluminum alloy as the main structural material. Aircraft skin, beams, ribs, stringers, bulkheads and landing gear aluminum alloy. The aircraft according to different purposes, the amount of aluminum is not the same. Focus on the economic benefits of commercial airplanes due to the aluminum alloy prices cheap large number of structural weight of the body, such as the Boeing 767 aircraft aluminum accounts for about 81%. Military aircraft requires good operational performance relative to reducing the amount of aluminum and some aluminum alloys such as high-performance fighter aircraft of maximum flight speed of Mach 2.5 F-15 is only 35.5% aluminum alloy has good low temperature performance in the -183 ~ -253 [2oc under cold brittleness in liquid hydrogen and liquid oxygen environment, it is concentrated **** and unsymmetrical dimethyl hydrazine can not afford chemical reaction, with good weldability, which is the manufacture of liquid rocket good material. The launch of "Apollo" spacecraft "Saturn 5 launch vehicle fuel tank levels, oxidants, boxes, box paragraph-level segment, the tail section, and the instrument module with aluminum alloy. The shuttle's crew cabin, the forward fuselage, center fuselage, aft fuselage, vertical tail, wing flaps, elevons and horizontal tail are aluminum alloy. The main structural material of a variety of artificial earth satellites and space probes are also aluminum Repair injury is an important part of the aluminum alloy forging process. Aluminum alloy is relatively soft at high temperatures, viscous, poor mobility, easy to stick the mold and produce a variety of surface defects (folding, burrs, cracks, etc.) must be polished, a process before proceeding to the next, and repair injury will clear the surface defects clean, otherwise defect in the follow-up process will further expand, and even lead to the forging scrap. Repair injury with tools, pneumatic grinding machines, wind and small cutter, power cutter and flat shovel. Repair injured first by corrosion to identify defective parts, repair the wound to be a smooth transition, and its width should be a depth of 5 to 10 times The extra-thick aluminum 7A52 superhard aluminum 7003 aluminum rod. |
