Whois & Analysis for blcastings.com

An engine block with aluminum and magnesium die castings.

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity.

The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.

Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys.

Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

Zinc is a chemical element with the symbol Zn and atomic number 30.

Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed.

It is the first element in group 12 (IIB) of the periodic table.

In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.

Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.

The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral.

The largest workable lodes are in Australia, Asia, and the United States.

Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13.

Aluminium has a density lower than those of other common metals, at approximately one third that of steel.

It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air.

Aluminium visually resembles silver, both in its color and in its great ability to reflect light.

It is soft, non-magnetic and ductile.

It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe.

The radioactivity of 26Al is used in radiodating.

These water valves are operated by rotary handles.

A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

China, officially the People's Republic of China (PRC), is a country in East Asia.

It is the world's most populous country, with a population of more than 1.4 billion people.

China spans five geographical time zones and borders 14 countries, the second most of any country in the world after Russia.

Covering an area of approximately, it is the world's third or fourth largest country.

The country consists of 23 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau).

The national capital is Beijing, and the most populous city and financial center is Shanghai.
