2017 fifth batch: aluminum, titanium alloy processing product quality supervision and inspection results
In the fifth installment of 2017, a total sample of Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangdong, Guangxi and Sichuan 931 batches of aluminum and titanium alloy processed products produced by 384 enterprises in 28 provinces, autonomous regions and municipalities including Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang.
The spot checks according to GB / T 5237.1-2008 "aluminum alloy building profiles Part 1 substrate", GB / T 5237.2-2008 "aluminum alloy building profiles Part 2 anodized profiles", GB / T 5237.3-2008 "aluminum alloy Building profiles - Part 3 Electrophoretic paint profiles ", GB / T 5237.4-2008" Aluminum alloy profiles - Part 4 Powder-coated profiles ", GB / T 5237.5-2008" Aluminum alloy profiles - Part 5 Fluorocarbon paint profiles " , GB / T 5237.6-2012 "aluminum alloy building profiles Part 6 insulation profiles" and other standards, the chemical composition of aluminum profiles (silicon, iron, copper, manganese, magnesium, chromium, zinc and titanium) , Tensile strength, non-proportional extension strength, elongation at break, minimum nominal wall thickness, wall thickness deviation, average film thickness, oxide film local film thickness, oxide film average film thickness, oxide film sealing quality, Film thickness, partial thickness of the composite film, hardness of the film, dry adhesion of the paint film, wet adhesion of the paint film, alkali resistance, minimum local thickness of the coating, dry adhesion of the coating, wet adhesion of the coating, Adhesion, coating indentation hardness, coating level According to GB / T 26060-2010 "Titanium and titanium alloy ingot", GB / T 3621 (GB / T3621), the thickness of the coating, the minimum local film thickness of the coating, the hardness of the coating and the longitudinal shear characteristics (room temperature) GB / T 3622-2012 "Titanium and titanium alloy strip and foil", GB / T 3624-2010 "Titanium and titanium alloy seamless pipe", GB / T 26058-2010 " Titanium and titanium alloy extruded tube ", GB / T 26057-2010" titanium and titanium alloy welded pipe ", GB / T 3625-2007" heat exchanger and condenser titanium and titanium alloy tube ", GB / T 2965-2007 Titanium and titanium alloy bar ", GB / T 3623-2007" titanium and titanium alloy wire "and other standards, the chemical composition of titanium and titanium alloy processing products (iron, carbon, hydrogen, oxygen, nitrogen, Tin, molybdenum, vanadium, zirconium, silicon, niobium, boron, manganese, palladium, nickel, chromium, copper, magnesium), tensile strength, Mouth experiment, low magnification and other 26 projects were tested.
Spot checks found that 74 batches of products do not meet the standards, related to iron, copper, zinc, manganese, tensile strength, non-proportional extension strength, minimum nominal wall thickness, wall thickness deviation, average film thickness, Local film thickness of anodic oxide film, local film thickness of the film, hardness of the film, partial film thickness of the composite film, alkali resistance, sealing quality, longitudinal shear characteristic value (room temperature), elongation at break, flattening experiment Mouth experiment, low magnification project.
