How to choose aluminum?Ordinary consumers in the purchase of aluminum can be identified visually by the simplest method, coating the substrate surface gloss, no cracks, aluminum ceiling section, no black, gray, green, hair, and other impurities, you then can look at the actual thickness of the coating section, some low-grade aluminum coating thickness will be to increase the strength of the board.
Some consumers generally believe that the thicker plate like, the hardness of the stronger the better. Led many manufacturers in order to meet their requirements, one-sided pursuit of thickness, hardness, surface treatment spray a layer of paint or more used some iron, lead, zinc and other heavy recovery miscellaneous aluminum plate pinch, this board price low hardness, thickness can meet.This will result in a composition ratio of the alloy can not be controlled, easily oxidized products, while due to extensive use of recycled aluminum, its toxic to humans, harmful to a large number of metal components exceeded, radioactive, human cells have a greater radiation and injuries, serious harm human health. This is one reason why the price of aluminum on the market there are increasingly rising very cheap Lvkou Ban.
How to store aluminum?Users need to store a few days after the purchase of aluminum, and vendors will be stored longer if proper storage of aluminum in this period of time, to avoid problems caused by unreasonable because the store? Today as we talk about aluminum storage precautions.Aluminum storage Note a: try to aluminum stored in the warehouse, if the conditions were not the case even in outdoor environments need protection rain cloth, avoid the rain, moisture causes oxidation of the aluminum surface appears white.
Aluminum storage Note II: aluminum during transport, must be covered with a tarpaulin to prevent rain, snow intrusion. Aluminum storage environment should be dry, bright, well-ventilated, non-corrosive climate, and should prevent rain, water, snow intrusion. Aluminum during storage, the bottom must be separated from the ground by the skids, keeping the ground distance is greater than 10CM. With no chemical materials and wet materials are stored together.
