Silicon Metal


We are the suppliers, super stockists & indenting agents of Silicon Metal.

SILICON, a tetravalent metalloid, is a chemical element with the symbol Si and atomic number 14.
Elemental silicon also has a large impact on the modern world economy. Although most free silicon is used in the steel refining, aluminum-casting, and fine chemical industries (often to make fumed silica), the relatively small portion of very highly purified silicon that is used in semiconductor electronics (< 10%) is perhaps even more critical. Because of wide use of silicon in integrated circuits, the basis of most computers, a great deal of modern technology depends on it.

PROPERTIES:

Silicon is a solid at room temperature, with relatively high melting and boiling points of 1414 and 3265 degrees Celsius respectively. It has a greater density in a liquid state than a solid state.
With a relatively high thermal conductivity of 149 W•m−1•K−1, silicon conducts heat well and as a result is not often used to insulate hot objects. In its crystalline form, pure silicon has a gray color and a metallic luster.
Most metallurgical silicon metal is used as an alloying agent in the aluminium industry due to its ability to increase the strength of aluminium. Demand from the aluminium industry has grown steadily in recent years due to increased usage of aluminium in structural engineering, aircraft manufacture and the automotive industry. Aluminium alloys are lighter and more resistant to corrosion than carbon-steel and can be made by addition of metals such as copper, zinc, magnesium, manganese as well as silicon.


METALLURGICAL GRADE & PRODUCTION:

Elemental silicon not alloyed with significant quantities of other elements, and usually > 95%, is often referred to loosely as silicon metal. Metallurgical grade silicon is commercially prepared by the reaction of high-purity silica with wood, charcoal, and coal in an electric arc furnace using carbon electrodes.
It being the carbo thermic reaction of silica (quartz) in an electric arc furnace using carbon electrodes where the temperature in the main reaction zone of temperatures exceeds 1800ºC
At temperatures over 1,900 °C (3,450 °F), the carbon in the aforementioned materials and the silicon undergo the chemical reaction
SiO2 + 2 C → Si + 2 CO.
Liquid silicon collects in the bottom of the furnace, which is then drained and cooled. The silicon produced this manner is called metallurgical grade silicon and is at least 98% pure.
Using this method, silicon carbide (SiC) may also form from an excess of carbon in one or both of the following ways:
SiO2 + C → SiO + CO or SiO + 2 C → SiC + CO.
However, provided the concentration of SiO2 is kept high, the silicon carbide can be eliminated by the chemical reaction
2 SiC + SiO2 → 3 Si + 2 CO
As noted above, metallurgical grade silicon "metal" has its primary use in the aluminum casting industry to make aluminum-silicon alloy parts. The remainder (about 45%) is used by the chemical industry, where it is primarily employed to make fumed silica.

APPLICATIONS:
Adding Silicon Metal to aluminium alloys makes them strong and light. As a result they are increasingly used in the automotive industry to replace heavier cast iron components. This allows weight reductions, a reduction in fuel consumption, increased efficiencies and subsequent benefits to the environment by reducing the greenhouse gas emissions and conserving fossil fuels.
There is increasing demand for Silicon Metal from the solar power generating industry where solar panels are made from silicon, which use the sun’s energy to produce domestic and industrial electricity. Silicon based polymers are also used as alternatives to hydrocarbon based products. They can appear in many every day products such as lubricants, greases, resins, skin and hair products. A more well known use of silicon is silicon chips, produced from semi-conductor grade silicon they are components in many every day electronic devices.

Manganese Metal


We are the most prominent suppliers of all grades and forms of Manganese Metal.
MANGANESE is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. Manganese is a metal with important industrial metal alloy uses.
Manganese is a pinkish-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute.
APPLICATIONS:
Manganese is essential to iron and steel production. Manganese is a key component of low-cost stainless steel formulations and certain widely used aluminum alloys. Manganese dioxide is also used as a catalyst. Manganese is used to decolorize glass and make violet coloured glass. Potassium permanganate is a potent oxidizer and used as a disinfectant. Other compound that find application are Manganese oxide (MnO) and manganese carbonate (MnCO3): the first goes into fertilizers and ceramics, the second is the starting material for making other manganese compounds.
In Copper Alloys:
Manganese is probably the most versatile element which can be added to copper alloys. Small additions of manganese (0.1 to 0.3%) are used to deoxidise the alloy and improve its castability and mechanical strength. Manganese has a high solid solubility in copper and in binary systems with copper and aluminum, zinc or nickel as the binary constituent. Many commercial copper alloys contain around 1 to 2% manganese to improve strength and hot workability. In order to reduce costs, manganese can replace part of the nickel in nickel-silver alloys.
In Aluminum Industry:
Manganese is used as an alloying element up to its solubility limit of about 1.5%. Aluminum-manganese alloys and aluminum-manganese-magnesium alloys, which have been sold under different trade names, have found applications in such diversified areas as kitchenware, roofing, car radiators and transportation. By far the most important use of aluminum-manganese alloys is for beverage cans, of which some 100 billion units are produced each year. The market for aluminum-manganese cans has grown steadily, thanks to the fact that such cans can be recycled.
Aluminum alloys containing up to 9% Mn have promising properties, but they cannot as yet be economically produced. Technologies to produce these commercial “amorphous” metals through very fast cooling are of potential interest but the processes used are still very expensive and can only be applied to high value materials used in the aerospace industry.
Other Applications:
Manganese is used in zinc alloys, but only at contents of 0.1 to 0.2%. It can also be used in magnesium alloys with the same content range, with the one exception of an alloy with 1.5% Mn.
Manganese can also be added to gold, silver, bismuth etc., to give alloys which are used for very specific applications, generally related to the electronic industry. The quantities involved are very small.

Magnesium Metal


We are the super-stockist & the largest suppliers of Magnesium Metal.
MAGNESIUM is a chemical element, designated by the symbol Mg. It has the atomic number 12.
Magnesium is the fourth-most-common element in the Earth as a whole (behind iron, oxygen and silicon), making up 13% of the planet's mass and a large fraction of the planet's mantle. Due to magnesium ion's high solubility in water, it is the third-most-abundant element dissolved in seawater. Magnesium is produced in stars larger than 3 solar masses by fusing helium and neon in the alpha process at temperatures above 600 Mega Kelvin.
Magnesium is generally obtained mainly by electrolysis of magnesium salts obtained from brine. In commerce, the chief use for the metal is as an alloying agent to make aluminium-magnesium alloys, sometimes called magnesium. Since magnesium is less dense than aluminium, these alloys are prized for their relative lightness and strength.
APPLICATION:
The main applications of magnesium are, in order: component of aluminium alloys, in die-casting (alloyed with zinc) to remove sulphur in the production of iron and steel, the production of titanium in the Kroll process. Magnesium, in its purest form, can be compared with aluminium, and is strong and light, so it is used in several high-volume part manufacturing applications, including automotive and truck components. Specialty, high-grade car wheels of magnesium alloy are called "mag wheels", although the term is often more broadly misapplied to include aluminium wheels.
The high magnesium content used for the crankcase of the late-World War II Wright Duplex Cyclone eighteen-cylinder radial aviation engine was a serious problem for the earliest examples of the Boeing B-29 heavy bomber, as engine fires in flight could ignite the engine crankcases, literally "torching" the wing spar apart in under a minute, causing wing failure.
PRODUCTS MADE OF MAGNESIUM:
Fire starter and shavings, sharpener, magnesium ribbon.
The second application field of magnesium is electronic devices. Because of low weight, and good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop and tablet computers, cameras, and other electronic components.
