The aluminum channel letter coil usually chooses 1050, 1060, 3003, 3105 and 5005 alloy. The choice depends on the surroundings. The tempers are H24, H26, H34. The thickness is 0.5mm, 0.6mm, 0.8mm and 1.0mm. The width is 30mm-500mm. The surface treatment includes coated, brushed, anodized and mirror finish.
The bath liquid for electrolytic coloring is mainly Ni salt, Sn salt and Ni-Sn mixed salt. Others with industrial applications include Fe, Mn, Cu salt, etc. The color is still mainly light tones, and dark colors include bronze, maroon, etc., but not much. However, the color of electrolytic coloring is very stable and light-resistant. After all, it is salt and an inorganic component.
The brushed aluminum strip now adopts double-roller rolling. The reduction amount of aluminum strip rolling should be controlled within the range of 12-16% according to the thickness of the aluminum strip, that is, the distance between the surfaces of the two rolling rollers is 84-88% of the thickness of the aluminum strip, so that the aluminum strip can produce a certain amount of plastic deformation and the convex and concave stripes on the roller are reversely printed onto the aluminum tape to form uniform and fine lines. The traveling speed of aluminum strip rolling is 100-150m/min.
The two main types of paint for color-coated aluminum strips are fluorocarbon (PVDF) and polyester (PE). The colors and effects of the paints can be the same, but the price difference between the two is not small. This is mainly because the paint costs are quite different. Fluorocarbon paint contains fluorine, which has better weather resistance, longer service life, and higher prices.
The type and thickness of coating depends on the balance between cost-effectiveness and performance. The service life depends on many factors, such as outdoor exposure conditions, cleaning and keeping the surface free of long-term contact with corrosive materials. Proper maintenance of its surface can extend its service life.
The price of aluminum strips of the same alloy will be affected by different widths and packaging methods. In principle, the smaller the width and the smaller the inner diameter, the higher the price. The common width is above 200 mm, and the commonly used inner diameter is 500 mm. Therefore, it is recommended that if the user has no clear requirements for the inner diameter, an inner diameter of 500 mm can be selected, and the width needs to be determined according to the actual need. The white aluminum strips are the common choice, so Haomei Aluminum usually have its stock. Welcome to leave message below to inquire what you need.
