FERRO SILICON


Ferro Silicon is an atomised alloy, which is formed by combining iron and silicon with a silicon content of around 75%. Ferro Silicon is a universal "heat-blocker" used in the production of carbon and stainless steels. This additive is used with other ferro alloys in the deoxidising process of steel, as well as in the production of silicon itself. Ferro Silicon is used in the production of cast iron, as Ferro Silicon can accelerate graphitisation. Ferro Silicon replaces the need for ferro manganese, spiegeleisen and calcium silicides in the manufacturing process.

MANGANESE ALLOYS

Manganese is the twelfth most abundant metal found within the Earth’s crust and derives its name from the Latin word Magnes which means Magnet. It is the fourth most used metal in terms of quantity behind iron, aluminium and copper. It was first used in the steel industry in Ancient Greece, the presence of manganese in the iron ore is most likely the reason that the weapons made by the Spartans were superior to their enemies. It was first isolated and recognised as an element in 1771 by a Swedish chemist called Scheele.

CHROME ALLOYS

Chrome is the twenty first most abundant element in the Earth’s crust, its name is derived from the Greek word Chroma to mean colour due to the many colourful compounds made from it. Chrome does not occur free in nature, rather as the mineral Chromite. Chromite ore was first discovered in the Ural mountains of Russia in 1778 and chrome metal was subsequently isolated by Nicholas Louis Vauquelin in Paris, France in 1797. Initially it was incorrectly identified as being a lead compound due to its metallic red appearance. South Africa has 90% of the world’s economic chrome reserves & produces over 50% of the worlds Chromite. Other producers are Kazakhstan & India with increasing amounts being produced in Turkey.

METALS

On a commercial scale metallurgical silicon metal is produced by the carbothermic reaction of silica (quartz) in an electric arc furnace using carbon electrodes where the temperature in the main reaction zone exceeds 1800ºC. Commercially produced metallurgical grade silicon metal is typically Si 98% pure and is notably produced in China, Russia, Brazil, Norway, South Africa and USA.

NICKEL & NICKEL ALLOYS

Nickel is a transition metal and naturally occurs extensively in the earth’s crust although the majority of it lies within the earth’s core so cannot be mined. It is a silvery-white lustrous metal & is the fifth most common element on earth. Nickel occurs most often with Iron and is commonly found in iron metereorites as the alloys kamacite and taenite. The bulk of the Nickel mined comes from two types of ore deposits; laterites and magmatic sulphide deposits. Nickel was first classified as a chemical element in 1751.

CALCIUM ALLOYS

Calcium alloys are an important compound used in several large scale manufacturing processes. Although there are many permutations for creating calcium alloys, the main types produced are Lead Calcium Alloy, Lead Calcium Tin Alloy and Magnesium Calcium Alloy. Small amounts of copper or sulphur are often added to improve the casting properties and make the alloy less corrosive. Other, less common calcium alloys include Calcium Aluminium Alloy and Calcium Silicon Alloy.
