    In recent years, with the rapid development of science and technology and industrial economy, the demand for aluminum alloy welded structural parts is growing, and the research on the weldability of aluminum alloy is becoming more and more in-depth. Aluminum alloy is one of the most widely used non-ferrous alloys in the industry. It is widely used in aviation, aerospace, automobile, machinery, shipbuilding and chemical industry.
    材料:鋁型材適用于優質鋁合金門窗,厚度,強度和噴涂顏色(一般噴涂,氟碳噴涂,電泳噴涂)等,必須符合國家相關標準,壁厚大于1.2毫米,抗拉伸力為每平方米157牛頓,屈服強度為每平方毫米10 8牛頓,氧化膜厚度應為10微米。如果不符合上述標準,則是不合格的鋁合金門窗,不能使用。
    Material: aluminum profile is applicable to high-quality aluminum alloy doors and windows. The thickness, strength and spraying color (general spraying, fluorocarbon spraying, electrophoretic spraying) must comply with relevant national standards. The wall thickness is greater than 1.2mm, the tensile strength is 157 Newtons per square meter, the yield strength is 108 Newtons per square millimeter, and the thickness of oxide film shall be 10 microns. If the above standards are not met, the aluminum alloy doors and windows are unqualified and cannot be used.
    The gaskets of aluminum alloy doors and broken bridge windows are usually used for PVC gaskets (limited by the state), nylon 66 gaskets (imported and domestic) and rubber gaskets (this insulation method does not meet the national standards). Remind everyone to choose the type of insulating strip.
    Processing: Bridge broken aluminum doors and windows equipment, high-quality aluminum alloy doors and windows, finishing, installation, pressure resistance, good sealing performance, switch free. Poor quality aluminum alloy doors and windows, blindly select aluminum profiles and specifications, process hard processing, cutting instead of milling, do not need to be installed, the ceiling performance is poor, the switch is not free, wind and rain and glass blasting are just phenomena. When external forces are involved, it is easy to squeeze or knock push-pull parts or glass, causing personal injury.
    Price: under normal circumstances, due to the high production cost, high-quality aluminum alloy doors and windows are 30% more expensive than low-quality aluminum alloy doors and windows. The wall thickness of some aluminum alloy doors and windows is only 0.6-0.8mm, and their tensile strength and yield strength are far lower than national standards, which is unsafe to use. In addition, it is recommended to use the products of conventional aluminum alloy door and window manufacturers, and the products that do not meet the standards are not easy to meet.
