Mirror aluminium sheet refers to the use of rolling, grinding and other methods of processing, so that the surface of the sheet presents a mirror effect. Usually abroad, the mirror aluminium sheet adopts the method of rolling to create a roll material and sheet material.
![[Image: aluminum-mirror-sheet.jpg]](http://thick-aluminum-plate.com/images/aluminumsheet/aluminum-mirror-sheet.jpg)
At present, there are two kinds of widely used mirror aluminium sheet. One is the pure aluminium sheet, common brands are 1050, 1070, 1085. They have a high content of aluminium and the purity is more than 99%. 1000 series mirror aluminium sheet production is relatively simple, so the price is cheap .Therefore,it is a series of applications in the conventional industry. The second is alloy aluminium sheet. The main brand is 5005 aluminium sheet and 5657 aluminium sheet. The main elements of 5000 series mirror aluminium sheet are magnesium and the content is from 3% to 5%. Therefore, it can also be called the mirror alloy aluminium sheet, the production process for continuous casting and rolling can be oxidized deep processing. At present, it is widely used in oil tank, machinery and other fields. 5000 series aluminium alloy sheet is a mature aluminum series and has a good mirror effect.
Mirror aluminium sheet is widely used and it is also one of the main products of many aluminum processing enterprises. As a leader in the domestic aluminum enterprises, haomei Aluminum Industry has a stable production and sales for the mirror aluminum.In building decoration, electronic equipment and other fields of applied materials, the mirror aluminium plate is very common, such as lighting, reflector, solar heat reflective materials, interior decoration, wall decoration, household appliance panel, electronic product shell, furniture kitchen, inside and outside decoration, signs, logo, bags and so on.

The crack in the hull of an aluminum high-speed catamaran last December in Hawaii triggered an investigation by the vessel's builder, its owner and the U.S. Coast Guard to determine the cause. Similar problems soon became apparent in other vessels recently built on the U.S. West Coast. The unexpected consensus: Some aluminum plates made of 5083-H321 composition used for recent vessel construction were found not to be resistant to corrosion in a saltwater environment.
In the past, builders of aluminum vessels had successfully used both 5083-H321 and 5083-H116. Although the two grades of aluminum differ somewhat in their physical characteristics, both have been generally referred to as marine grade and used in saltwater environments.
After December's discovery, the shipyards moved quickly to fix all damage, including replacement of undamaged but nevertheless noncorrosion-resistant aluminum as determined by testing.
Nichols Bros. Boat Builders' initial response was typical. A boat it had built for service in Southern California was found to have cracks in the middle of 3/16-inch-thick aluminum plates mainly in the engine room and water jet pump room.
"We brought the boat back into our yard and ran a double shift," said Matt Nichols, president of Nichols Bros. "We had to lift the deckhouse off, and replaced with all new material some longitudinal stringers, plates and anything attached." The work, he said was "taken care of by us at great expense, but the customer is extremely pleased."
At Kvichak Marine Industries, the response was equally fast to resolve the problems when the first reports came of defoliation and cracking of the aluminum hull on the Hawaii catamaran.
The Coast Guard's Puget Sound Marine Safety Office identified Nichols Bros., Kvichak Marine and Norsco Marine as the shipyards affected, and Reynolds Metals Company, Alcan Aluminum Corp. and Integris Metals as suppliers of the material.
The extent of the problem is still unknown. In a lawsuit, Nichols Bros. contended "the problem could affect at least 25 vessels built by several shipyards and their total value could exceed $50 million."
Apparently, the shipyards relied on the commonly used product terminology of "marine-grade aluminum" when purchasing materials for these vessels. But this time, Matt Nichols said, "the 5083-H321 was not corrosion-resistant like it was supposed to be. Once salt water got on the material, it started a process of breaking the material down and defoliation would begin."
In early February, Integris Metals stated in a letter that the 5083-H321 it supplied was not guaranteed for marine use and could be susceptible to corrosion when exposed to salt water. On March 11, the issue moved to court when Nichols Bros. filed a lawsuit in U.S. District Court against both Reynolds and Alcan to recover damages. The complaint alleged that "Reynolds knew the aluminum Nichols sought was intended for use on a passenger ferry to be used in a marine environment, and that the aluminum would have to be marine grade." Although the aluminum suppliers had "delivered certificates of conformance ... that the aluminum had the characteristics that made it marine grade, the material delivered in fact was not marine-grade." Further, the complaint contended that because of Reynolds' "skill and experience" in supplying aluminum, "Nichols left up to Reynolds the choice of aluminum between 5083-H116 and 5083-H321 to supply for use."
5083-H321 has been successfully used for other vessel construction. One Far Eastern shipyard said that while that material "does not require painting for corrosion protection, it may be advisable to fill and fair hull exteriors and superstructure above the waterline with an epoxy micro-balloon filler."
In this current problem, Matt Nichols said the low corrosion resistance of the 5083-H321 supplied may be related to a production factor.
"Basically, the Alcan plant in Oswego, N.Y., that was doing the manufacturing changed the procedure from a hot-rolled process to a cold-rolled process," he said. "In hot rolling, the particles of the components of the material were distributed much better, in a more fluid and more uniform manner. The cold-rolled process just wasn't as uniform. Once salt water got on the material, corrosion, defoliation and cracking would begin."
Another factor may be the degree of magnesium particles between grain boundaries in the aluminum microstructure. An independent metallurgist also advised the Coast Guard that factors such as vibration, operational heat from engines, high ambient temperatures and vessel stresses could accelerate the development of cracks.
But in selecting an appropriate aluminum material for corrosive atmospheres, one aluminum supplier that is not involved in the dispute recommends 5083-H116 because "this temper (H116) has characteristics which substantially eliminate the susceptibility of alloy 5083 to exfoliate under certain corrosion conditions."
Ultimately, defining different tempers of 5083 aluminum and their production methods for use as "marine grade" may have to be clarified. Lt. Cmdr. Tom Miller, chief of inspections with the Coast Guard's Puget Sound Marine Safety Office, noted that while both 5083-H116 and 5083-H321 currently are used for vessel construction, "It could be argued there is a marine-grade standard, but it is not explicitly defined. That may need to happen."
Attempts to resolve the issue out of court by negotiations are underway.
A team from Alcoa Inc., Alcan and Integris Metals is "currently gathering information and communicating directly with boat builders and the Coast Guard," according to the companies.
A meeting at Nichols Bros. with the aluminum suppliers in late March was "very positive, very upbeat," Nichols said. The Alcan-Reynolds-Integris project team also met with the Coast Guard in early April.
For the shipyards, attempting to recover the costs for the vessel repairs from the aluminum suppliers is one part of their problem. Another is scheduling vessel repairs with suitable aluminum into the sequence of other jobs underway in the yards.
"The shipyards will work through this with their customers," said one industry source. Matt Nichols was also positive: "Those material problems are just something that will not happen again."

Mostly, it blocks out the light. It also blocks infrared radiation, so it keeps sunlight from heating the inside. And it blocks radio waves, so it makes it harder for your cellphone to get a signal, as well as makes it harder for your neighbors to hijack your WiFi.
But mostly it's to block out light, for people who are willing to be penny wise and pound foolish.

Nalco, in collaboration with the Odisha government-owned Industrial Infrastructure Development Corporation (Idco), is developing an aluminium downstream park at Angul in the eastern region. The facility is spread over 240 acres and in the project, both Nalco and Idco are joint equity partners. The park is strategically located in the vicinity of Nalco’s aluminium smelting complex at Angul. The park is modelled on Sohar Aluminium’s cluster in Oman where molten aluminium is supplied to the downstream units. This saves on logistical costs and also ensures continuous raw material supplies. In India, this is the first of its kind project, whereby molten aluminium would be sourced directly to feed the downstream units at the park. But, both Nalco and Idco- the equity holders in the aluminium park have gone beyond the commitment of raw material supply.
Nalco has committed a supply of at least 50,000 tonnes of molten aluminium every year to the downstream units who set up shop in the park. The supply can expand to 100,000 tonnes every year depending on the demand from the units. Nalco is also providing a pricing discount of Rs 5000 per tonne on aluminium ingots and Rs 4000 a tonne on molten metal. Leaving that aside, Nalco is lending its brand name to the products to be manufactured by the downstream industries. Land price for the units has also been slashed by 20 per cent. With such an array of incentives on offer, the downstream units can save up to Rs 10,000 per tonne. This cluster model has potentially positioned this cluster as amongst the most globally competitive aluminium parks in the world.
The Angul aluminium park is built with a cost of Rs 180 crore (or $28 million) on infrastructure. The aluminium park would reflect a complete industrial state-of-the-art entity, fully equipped with logistics infrastructure facility, an exclusive training centre, a park administration and a display & trade services facility. The park would also contain an Aluminium Product Evaluation Centre (APEC) furnished with a fully-fledged tool room, testing, simulation and evaluation facilities, processing hall and prototype development facility to foster innovation and deliver excellence in terms of quality.
Learning from the Nalco example, Vedanta has planned to develop a similar downstream aluminium park. The company has identified 240 acres of land around the site of its aluminium smelter at Jharsuguda in Odisha’s western belt. Expected to house more than 100 downstream units, the proposed aluminium park has the potential to attract investments worth Rs 1000 crore. This state-of-the-art plug-and-produce aluminium park will be set up across 240 acres of land, providing an exclusive ecosystem for industries dependent on as well as manufacturing aluminium conductors, extrusions, castings, foils, powder and paste. The aluminium park will facilitate easy transport of aluminium in liquid form, resulting in substantial cost savings that will be a game-changer for the downstream industries. With a holistic ecosystem in place, the park is expected to attract a large number of aluminium/aluminium based industries generating huge revenues and employment in the region.
