About aluminum extrusions

With the rapid advance of large-scale investment in infrastructure and industrialization process, the production and consumption of aluminum industry's rapid growth, while China also became the world's largest aluminum production base and consumer market. After more than 10 years of rapid growth, China's aluminum industry entered a new stage of development, and show a lot of new trends.
Aluminum extrusions is the industry's most widely used class of non-ferrous structural materials in aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration. And the chemical industry has a large number of applications. With the recent rapid development of science and technology as well as the industrial economy, the demand for aluminum welded structure is increasing, so the welding of aluminum also will be in-depth. Aluminum extrusions is the industry's most widely used class of non-ferrous structural materials in aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration. And the chemical industry has a large number of applications. With the recent rapid development of science and technology as well as the industrial economy, the demand for aluminum welded structure is increasing, so the welding of aluminum also will be in-depth. Aluminum is widely used to promote the development of aluminum welding technology, welding technology while developing and expanding the applications of aluminum, aluminum welding technology is becoming one of the hot research. Aluminum extrusions products with high strength, light weight, corrosion resistance, decorative, long life, rich colors and so on. Generally, a good product in 20 years without losing its surface light, not color.
Extruded aluminum profiles forming the means. The first product based on the profile section design, manufacture molds, use a good round heated extruder die casting rods from extruding. Grade 6063 alloy commonly used in artificial aging process Shihai extruded aluminum with an air-cooled quenching process and subsequent to the completion of heat strengthened. Different grades can be heat strengthened alloys, different heat treatment system. Good aluminum profiles extrusion, surface corrosion resistance is not strong, have to be surface treated by anodic oxidation of aluminum to increase the aesthetics of corrosion resistance, abrasion resistance, and appearance. In the production of extruded aluminum extrusion die in working conditions is very bad, both need to withstand intense friction and wear at high temperatures, high pressure, and also need to withstand cyclic loading. This requires a mold having a high thermal stability, thermal fatigue resistance, wear resistance and sufficient toughness heat.
