We produce numerous varieties of foundry products. All of these are ferrosilicon-based and are special elements that give specific metallurgical properties to products they are used in. 30% of the production is used to manufacture water supply, oil and gas pipelines 70% is used in appliions where strength and formability are required (i.e., automotive components) What are nodularisers? The

Metal audit Rare earth and strategic metals prices Monthly, mostly daily updated, we provide the prices of around 650 individual values from the fields of rare earth metals, strategic metals, base metals, high-purity metals and isotopes online. A database of
Major producers manufacture acetylene by either the partial oxidation of natural gas or as a coproduct of the thermal cracking of ethylene; minor producers manufacture acetylene from calcium carbide. About 80% of production is used as a closed system intermediate in the manufacture of acetylene black as well as acetylenic and vinyl derivatives used in a variety of appliions such as the
Materials available include high purity metal powders and compounds, alloys, ceramics, plastics, and composites—all in a variety of particle sizes. MIL-SPEC MATERIALS Atlantic Equipment Engineers has been a trusted source of mil-spec materials for over 50 years—established originally to meet the needs of NASA and other U.S Department of Defense research and development programs.
SILICON METAL Silicon Metal is known as a semi-metallic or metalloid, having several of the characteristics of metals. It is the second most abundant element in the Earth''s crust after oxygen, naturally occurring in various forms of silicon dioxide or silies and very rarely in its pure form in volcanic exhalations.
2020/1/15· Like aluminum, beryllium metal forms an oxide layer on its surface that helps to resist corrosion.The metal is both non-magnetic and non-sparking—properties valued in the oil and gas field—and it has a high thermal conductivity over a range of …

2019/11/20· The state-controlled Chinese metals producer China Minmetals Corp. is China’s biggest and most international metal ore mining company is headquartered in Beijing. With mines in Australia, South America, Africa and other parts of Asia, China Minmetals is involved in the production of virtually every metal, including copper, aluminum , tungsten , tin , antimony , lead, zinc, rare earths, and
The end-Permian mass extinction horizon is marked by an abrupt shift in style of carbonate sedimentation and a negative excursion in the carbon isotope ( δ 13C) composition of carbonate minerals. Several extinction scenarios consistent with these observations have been put forward. Secular variation in the calcium isotope ( δ 44/40Ca) composition of marine sediments provides a tool for
It is a refractory metal due to its relatively high melting point, oxidizes immediately upon exposure to air and is on of the few elements that burn in pure nitrogen gas. Extracting titanium is difficult and costly and the most efficient way to produce it is using the Kroll process.

Vanadium metal, sheet, strip, foil, bar, wire, and tubing have found use in high-temperature service, in the chemical industry, and in bonding other metals.Because the major commercial use of vanadium is in steel and cast iron, to which it lends ductility and shock resistance, most of the vanadium produced is used with iron as ferrovanadium (about 85 percent vanadium) in making vanadium steels.
However, nothin’ doin’ on the rare earth metal prices front for the last month on our price index…and perhaps not much activity to come in the 2014 rare earths price forecast, either.
