New closed arms for luminaire in zamak

IRILUR S. L. - Lamps and accessories for lamps, has once again put its trust in us to create and merge their new closed arms for luminaire in zamak. After months of work we can say that their new design is ready to be added to IRILUR`s catalog of products.

Unlike the majority of companies of lamps or accessories for lamps, IRILUR S. L. takes you from the years 80 using the zinc alloy "zamak", applied with success to manufacture their lighting products, obtaining forms and geometries not possible with other materials with the exception of the plastics, And by another dramatic improvements of surface finish due to its dimensional stability and smoothness to the obtainable in the surfaces, by deleting processes of filing and polishing that fatally entered, in the brass castings and bronze, and to a lesser proportion in the bilberry, controllable little variations of the originally projected forms (especially in edges and curves of small radio). This protection is obtained either with organic coatings (paints, varnishes, lacquers and enamels) or by electrolytic coatings that, in the brasses are generally of nickel and chrome, and in the case of zamak tend to be copper-nickel-chrome.

Neither must we forget the possibility that has the zamak, like the other metals and certain plastics, coatings to incorporate the tribology of PVD (Physical Vapor Deposition), CVD (Chemical Vapor Deposition) or of PECVD (enhaced Plasma Chemical Vapor Deposition) or The most recent on the basis of nickel alloys and tungsten, which in certain cases are substituting or substituted for the coatings to electrolytic nickel base and chrome that, among the other characteristics do not affect the environment or the health.

Handling of Aluminum by Goldman Sachs

The North American investment banks Goldman Sachs and JP Morgan are accused of manipulating the price of aluminum by moving their stocks from different warehouses, generating queues in order, longer delivery times, generates premiums for customers wishing to be delivered quickly, which affects the entire market and can artificially inflate the price of the metal.

LME aluminum storage banks goldman-sachs



Several complaints
The complaint stems from a large trans-Atlantic users of aluminum, MillerCoors, a brewer using cans. According to MillerCoors, the aluminum price was inflated by $ 3 billion last year worldwide. Another complaint partnership has been filed in Florida, August 7, accusing the London Metal Exchange (LME), Goldman Sachs, JPMorgan Chase and Glencore Xstrata cartel in aluminum storage.

The technique of suspected fraud
The process is simple because the law requires holders of aluminum to physically go out every day 3,000 tons of their warehouse but it does not say that the aluminum to be delivered. Then just move legally aluminum of a warehouse to another. Goldman Sachs and physically stores of aluminum in 27 warehouses around Detroit. The New York Times, after an investigation revealed that a fleet of trucks will carry a daily aluminum and forth between a warehouse and another. This movement of goods would lengthen delivery times can spend six weeks to over a year. And storage is longer and the invoice to the customer is high for those who want to be delivered quickly pay a premium.

The control of raw materials by banks such as Goldman Sachs' allows them to both predict and influence commodity prices and thus determine the pricing of derivatives and hedge funds in particular on raw materials "says U.S. News.

The role not so clear LME
The LME (London Metal Exchange), which should play a regulatory role in this market is not neutral and is involved because the LME affects 1% of the rental of warehouses and is far from being independent since held until last year by banks with Golman Sachs.

The Fed survey
Given the spate of allegations of fraud, the U.S. central bank (Fed) investigates the physical assets of raw materials held by many banks. In particular it could return to the authorization granted in 2003 to conduct such activities in addition to their sawmills derivatives and commodities brokerage.

Denial of Goldman Sachs
The bank denies any dispute handling and the storage of aluminum can drive up prices. They readily believe, given the reputation of profound honesty that surrounds all of their activities.
