Non-ferrous metals are metals that do not contain iron. There are two groups of metals; ferrous and non-ferrous. Ferrous metals contain iron, for example carbon steel, stainless steel (both alloys; mixtures of metals) and wrought iron. The LME offers futures, options and TAPOs contracts for aluminium, copper, nickel, tin, zinc and lead plus two regional aluminium alloy contracts. Non-ferrous metals don't contain iron, for example aluminium, brass, copper (which can be remembered as ABC) and titanium. You can also get non-ferrous metals as alloys eg, brass is an alloy of copper and zinc. This section of the website allows you to find out more information about the specific products offered including contract specifications, LME listed brands, trading times and committee information.
Nonferrous metals are specified for structural applications requiring reduced weight, higher strength, nonmagnetic properties, higher melting points, or resistance to chemical and atmospheric corrosion. They are also specified for electrical and electronic applications. The most commonly used non-ferrous metals are aluminium, copper, lead, zinc, nickel, titanium, cobalt, chromium and precious metals. Millions of tonnes of nonferrous scrap are recovered annually and used by smelters, refiners, ingot makers, foundries, and other manufacturers. Secondary materials are essential to the industry’s survival because even new metals often require the combined use of recycled materials.

What is Sodium bromide
Sodium bromide, also known as sedoneural is a high-melting white, crystalline solid that resembles sodium chloride. Identifying information, including synonyms, ID numbers, use type, chemical classification, a link to a list of all products containing this chemical and a list of the top crops this pesticide is used on in California. Molecular Weight: 102.894 g/mol.
It is a widely used source of the bromide ion.NaBr is used in organic synthesis as a source of the bromide nucleophile to convert alkyl chlorides to more reactive alkyl bromides by the Finkelstein reaction.Sodium bromide also can be used as a source of the chemical element bromine. Sodium Bromide treatments should be done cautiously, and definitely NOT in biguanide (SoftSwim or Baquacil) treated swimming pools. Molecular formula: NaBr.
Sodium Bromide is used in photographic processing, as a chemical intermediate for the manufacture of various chemicals, and bromides. Sodium bromide is used to prepare dense fluids used in oil wells. This can be accomplished by bubbling chlorine gas through an aqueous solution of NaBr. Since sodium bromide cannot be removed from the water, you effectively transform the pool to a "bromine" treated pool. CAS:7647-15-6. It is used for water clarification. Pharmaceutical grade is used in medicine as sedatives.

What is Electrolytic copper powder
Electrolytic copper powder is produced by following principles used in electroplating with the conditions changed to produce a loose powdery deposit rather than a smooth adherently solid layer.
In most cases, the powders will be metallic, although in many instances they are combined with other phases such as ceramics or polymers. They are compressible like a gas. But the compression of a metal powder is essentially irreversible, like the plastic deformation of a metal. Thus, a metal powder is easily shaped, with the desirable behavior of a solid after processing.
The copper powder obtained by electrolysis is high purity material, averaging more than 99% copper. CAS:7440-50-8. Powders exhibit behavior that is intermediate between that of a solid and a liquid. Powders will flow under gravity to fill containers or die cavities, so in this sense they behave like liquids. The effect of electrochemical and mechanical variables on the physical characteristics of electrolytic copper powder is also reviewed.
Electrolytic copper powder is widely used in diamond tools, carbon brushes friction materials, P/M products and abrasive materials, pastes, electrical and electronic applications.

Where to Get Copper Powder
Copper powder offers the engineer a means conserving materials, reducing machining and securing a uniform product at a reasonable cost. This unique metal-forming method permits the production of parts with close tolerances and a minimum of scrap. It also enables the development of products that cannot be produced by any other method. Density can be controlled to produce parts with porosities as high as 60% or, conversely, those that are practically pore-free and have densities approaching the theoretical density of the metal. It is also possible to vary the density in a single part.
Electrolytic copper powder is produced by following principles used in electroplating with the conditions changed to produce a loose powdery deposit rather than a smooth adherently solid layer. The copper powder obtained by electrolysis is high purity material, averaging more than 99% copper.
Superfine copper powder is a light rosy,dendritic,readily oxidize in the moist air and soluble in heated sulfuric acid or nitric acid. It is widely used in manufacturing diamond tools,cargon brushes,friction materials,pastes and other powder metallurgy products as well as electron industry.
Copper powders have been used in industrial applications for many years. Probably the best known is the self-lubricating bearing which was the first major application and still accounts for about 70% of the granular copper powder used. This application takes advantage of the ability to produce a component with controlled interconnected and surface-connected porosity.

How to Buy Caesium
Caesium or cesium is the chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (83 °F), which makes it one of only five metals that are liquid at or near room temperature. Caesium is most notably used in atomic clocks. Also webmasters and bloggers for instance need to make sure the images they post on their websites are optimized, to avoid prolonged loading times for their visitors. The software allows you to view instantly the compression results, helping you to decide how much optimization you need. Caesium-based atomic clocks observe electromagnetic transitions in the hyperfine structure of caesium-133 atoms and use it as a reference point.
Caesium metal is highly reactive and very pyrophoric. In addition to igniting spontaneously in air, it reacts explosively with water even at low temperatures, more so than other members of the first group of the periodic table. Caesium is a very soft (it has the lowest Mohs hardness of all elements (0.2)), very ductile, silvery-white metal, which develops a silvery-gold hue in the presence of trace amounts of oxygen.
Caesium is a relatively rare element as it is estimated to average approximately 3 parts per million in the Earth's crust. Caesium can set different compression levels to each image, saving a lot of time, ensuring great results!
The mining of pollucite ore is a selective process and is conducted on a small scale in comparison with most metal mining operations. The ore is crushed, hand-sorted, but not usually concentrated, and then ground. Otherwise, it depends on whether the caesium lands on farms and gardens, or relatively undisturbed forests and mountains. Symbol: Cs; Atomic Number: 55; Atomic weight: 132.9054519.

How to Buy Caesium iodide
Caesium iodide is a very useful material with a transmission range from the visible
region out to 70 microns through to a 2mm thick window. CsI is very soft and water-
soluble and when humidity is relatively high polished surfaces may be damaged by moisture
in the atmosphere. CsI has a wider transmission range than the more common potassium
bromide beamsplitters, extending usefulness into the far infrared. A problem with
optical-quality CsI crystals is that they are very soft with no cleavage, making it
difficult to create a flat polished surface.
Caesium Iodide is hygroscopic and readily dissolves in water. This property means that it
needs to be kept away from water and also makes it difficult to polish.
An important application of caesium iodide crystals, which are scintillators, is
electromagnetic calorimetry in experimental particle physics, and is sometimes used for
components in the widest range spectrophotometers. An extremely soft material, Caesium
Iodide is extremely difficult to polish, and so performance is compromised for range.
Doped with Thallium, CsI(Tl) is a useful scintillator which emits at a wavelength that is
a good match for Silicon photodiodes. Arrays of Caesium Iodide are used in security
imaging systems. Principally used for Infrared Spectroscopic windows and also for beam
splitters in FTIR Instumentation. CsI is also available thallium doped for scintillation
applications. It is an ionic compound often used as the input phosphor of an x-ray image
intensifier tube found in fluoroscopy equipment.
