With higher pursuit of the aluminum sheet properties, the demand for alloy 3003 and 3004 both keeps increasing. There is more demand for 3004 aluminum plates especially for the factory projects.Alloy 3003 is the the most commonly used product in terms of sales volume and user acceptance. It has excellent anti-rust performance,good forming performance and high hardness. The high-speed traffic signs, building signs, high-speed barriers, building shells, etc., are all its popular applications.Alloy 3004 basically has the same requirements in all aspects with the 3003 aluminum plate, but its strength is higher than that of alloy 3003. 3004 aluminum sheet is of the better formability, solubility, corrosion resistance. That’s why many projects gradually abandon 3003 aluminum sheet to choose 3004 aluminum sheet.Alloy 3003 VS Alloy 3004Chemical elementThe chemical composition "Mg element" of 3004 aluminum plate is much higher than that of 3003 aluminum plate. At the same time, “magnesium element” is also the item with the biggest difference in chemical composition between 3003 aluminum plate and 3004 aluminum plate.3003 aluminum properties V 3004ItemTensile strength (Rm/MPa)Yield strength(Rp0.2/MPa)DensityAlloy 3003142-178150～2852.71Alloy 3004150-285110Most of alloy 3004 are made by hot rolling, so the price of 3004 aluminum sheet is much more expensive than 3003 aluminum sheet.
