iron casting MacKenzie in his l944 Howe Memorial Lecture referred to cast iron as "steel plus graphite." Although this simple definition still applies, the properties of gray iron are affected by the amount of graphite present as well as the shape, size, and distribution of the graphite flakes. Although the matrix resembles steel, the silicon content is generally higher than for cast steels, and the higher silicon content together with cooling rate influences the amount of carbon in the matrix. Gray iron belongs to a family of high-carbon silicon alloys which include malleable and nodular irons. With the exception of magnesium or other nodularizing elements in nodular iron, it is possible through variations in melting and foundry practice to produce all three materials from the same composition. In spite of the widespread use of gray iron, the metallurgy of it is not clearly understood by many users and even producers of the material. One of the first and most complete discussions of the mechanism of solidification of cast irons was presented in 1946 by Boyles. Detailed discussions of the metallurgy of gray iron may be found in readily available handbooks. The most recent review of cast iron metallurgy and the formation of graphite is one by Wieser et all.

Radiators and convectors are types of heat exchangers designed to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics.
One might expect the term ¡°radiator¡± to apply to devices which transfer heat primarily by thermal radiation (see: infrared heating), while a device which relied primarily on natural or forced convection would be called a ¡°convector¡±.Radiator,China radiator,,aluminium radiator,electric radiator,oil radiator,radiator manufacturer,Bathroom radiator ,towel radiator ,Electric towel warmer

The term ¡°convector¡± refers to a class of devices in which the source of heat is not directly exposed
Furniture is the collective term for the movable objects which may support the human body (seating furniture and beds), provide storage, or hold objects on horizontal surfaces above the ground. Storage furniture (which often makes use of doors, drawers, and shelves) is used to hold or contain smaller objects such as clothes, tools, books, and household goods. (See List of furniture types.)
Furniture can be a product of artistic design and is considered a form of decorative art. In addition to furniture¡¯s functional role, it can serve a symbolic or religious purpose.
