Prices of aluminum sheet coil

February 5, 2020

Prices of aluminum sheet coil ranges roughly between $2200 and $4000 per metric ton. It’s difficult to have them listed because it would take up at least hundreds of pages since there are so many alloys, process methods, specifications and even price types, all of which affect the eventual harga aluminum sheet coil. Why, you might ask, a 5xxx aluminium mirror sheet is more expensive than a plain 5000 sheet?

First we deal with alloys. 1xxx coil sheets, also known as pure aluminum plates, contain the highest content of aluminum among all series. They are the lowest in either per unit weight or corrosion resistance. The 3 series aluminum plates have good rust prevention performance, good formability, high corrosion resistance and high strength. 5 series aluminum plate rolls display light weight, high strength, easy painting property, low density, good heat dissipation and strong compression resistance. They can fully meet the requirements of 3C products with high integration, thinness, miniaturization, anti-collision, electromagnetic shielding and heat dissipation. Its hardness is several times that of traditional plastic cases, but its weight is only one-third of the latter. The price of these aluminum alloy sheets is generally between $2200 to 3000$. 6XXX series aluminum alloy, also known as “aluminum-magnesium-silicon alloy”, is a heat-resistant corrosion-resistant aluminum alloy with high strength and corrosion resistance and good uniformity, and 7xxx alloys, represented by 7075 t6 and 7075 t651, boast even better performances in aspects above. Therefore, the harga aluminum sheet coil of 6000 and 7000 series is higher, remaining $3000/mt and above regardless of processing methods. 8xxx aluminium products are usually of foil type, the price of which is no more than $3000/mt most of the time. All of the prices mentioned above are for mill finish sheets, namely, sheets without complicated further process methods.

Second, harga aluminum sheet coil has a lot to do with process methods of the sheet coil as well. In addition to mill finish, relative process methods also include mill finish, mirror finish, anodizing, color coating, embossing etc. Extra process steps indicate extra costs. Take mirror finish for example, it entails adoption of a polishing machine in which a sheet is dealt with for hours. This means rises in machinery cost, labor cost and time cost. Further more, such a price increase is based on the price of aluminum sheet plates of given alloys. In other words, 1060 mirror sheets are much cheaper than 6061 ones. It is the same case with other methods. The price can be even higher if two or more of these processes are combined. As a result, an anodized reflective aluminum sheet can be $500/mt more expensive than regular sheets.

In many cases, prices of aluminum sheet coil are related to uses, which, however, corresponds with specific alloys and process methods most of the time. Pure aluminum plate are usually used to make some structural parts with specific properties, such as gaskets and capacitors made of aluminum foil, electronic tube insulation nets, protective covers for wires, cables, nets, cores, and aircraft ventilation system parts and decorative parts . The 3 series aluminum plates are mostly used in places where anti-corrosion and rust resistance are required, such as pipe insulation, non-slip construction of cold storage floors; 5 series aluminum plates are more used in manufacturing industries, such as ships, automobiles, radiators, etc. 6XXX series aluminum alloy is mainly used for extruded profiles. 7 series aluminum plates are widely used in the aviation industry. Mainly used in: aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper plastic mold, foaming mold, wax removal mold, template, fixture, mechanical equipment, mold processing, High-end aluminum alloy bicycle frames, etc. That’s why aluminium sheet coil suppliers would ask you about uses when you are asking for a price.
