SMM A00 Aluminum Ingot(CNY/mt)
On June 6th, the price of SMM A00 aluminum dropped by CNY 40/Mt compared with the previous trading day.On the macro level, the call between the Chinese and American heads of state sent a positive signal of easing trade frictions. If the US side can be prompted to withdraw unfavorable measures, the external environment of the aluminum market will be further improved. In addition, the interest rate cut by the European Central Bank will form a relatively direct and clear positive stimulus to aluminum prices, bringing additional support. On the fundamentals, the domestic raw aluminum operating capacity remains stable, and the subsequent ingot volume is expected to decline slightly. The domestic aluminum ingot inventory will temporarily maintain a destocking trend. On the cost side, the impact of the Guinea mine incident on alumina prices has eased, and the real-time cost of raw aluminum has declined slightly month-on-month. On the demand side, facing the dual pressures of seasonal weakness and trade uncertainty, the operating rate of aluminum processing enterprises is under pressure in the short term, the off-season atmosphere has intensified, and new orders in industries such as building materials, photovoltaics, and automobiles have shown signs of weakness. Overall, the current low inventory and the expectation of an increase in the proportion of aluminum liquid provide strong support for aluminum prices. However, the overall macroeconomic situation during the week was bearish, and aluminum prices were under pressure at a high level. The off-season pressure on the demand side limited the room for aluminum prices to rise. Spot aluminum ingots in major consumer areas may soon face a situation of weak supply and demand. In the short term, aluminum prices may maintain a sluggish consolidation pattern.

Performance comparison of 3004 colored aluminum coil and colored steel coil
3004 colored aluminum coil and colored steel coil are both widely used in building roofs and cladding, but their performance is quite different. When choosing building materials, it is necessary to consider the building design requirements and the performance requirements of the materials.
Durability comparison
3004 color coated aluminum coil: 3004 color coated aluminum coil can form an aluminum oxide film with the atmosphere to prevent further corrosion. Under normal environmental conditions, PE coating comes with a 15 year warranty and PVDF coating comes with a 30-year warranty
Color steel coils: Color steel coils are prone to corrosion, rusting, and fracture accidents at rivets and joints under the erosion of humid air, rain, and snow, and their service life is affected by the application environment.
Weight comparison
3004 color coated aluminum coil:3004 colored aluminum coil is lightweight with a density of 2730 kilograms per square meter,and are suitable for buildings with lightweight requirements
Color steel coils: Color coated steel coils are relatively heavy in weight, with a density of 7850 kilograms per square meter, and are suitable for buildings that require hardness and strength
Strength comparsion
3004 color coated aluminum coil:3004 colored aluminum coil contains magnesium and manganese elements, which have certain strength and stiffness
Color steel coils:Color steel aluminum coil has good strength and stiffness, and is more suitable for steel structures
Lightning protection performance
3004 color coated aluminum coil:The thickness of 3004 colored aluminum coil commonly used for aluminum roofs is 0.7mm and 0.9mm, which can be directly used as lightning arrester to avoid perforation on the roof
Color steel coils:The thickness of the color steel aluminum coil commonly used for aluminum roofs is 0.5mm, and it cannot be directly used as a lightning arrester. An additional lightning arrester needs to be installed
Safety and fire resistance comparison
3004 colored aluminum coil:3004 colored aluminum coil is a non-flammable metal material with a low melting point. It will form an aluminum oxide protective layer at high temperatures to delay further oxidation.
Color steel coils:Color coated steel coils have a high melting point and are not flammable at room temperature, but are easily bended and deformed at high temperatures, causing large-scale collapse of buildings.
Processing performance comparison
3004 color coated aluminum coil:3004 color coated aluminum coil has good bending resistance and weldability. After cold treatment, the strength and ductility of the aluminum alloy are improved, making it suitable for complex processing and less prone to deformation
Color steel coils:Color steel coils have high hardness and are prone to breakage during bending and welding processes
Cost-effectiveness comparison
3004 color coated aluminum coil:3004 colored aluminum coil material has a high price but a long service life, can be self-cleaning and maintenance free, with high cost-effectiveness
Color steel coils:Color steel coil material has a low price, but its service life is only 1/3 of that of color aluminum coil. It is prone to rusting in high humidity environments and requires rust prevention treatment and regular maintenance. If there is extensive corrosion, the maintenance and renovation costs will be higher
