What is CGI cast iron?

Compacted Graphite Iron, which is also known as CGI or Vermicular Graphite Iron, is a form of cast iron in which the shape of the graphite particles is between that of conventional grey iron flakes and ductile iron where the graphite is in spheres.

Is compacted graphite iron stronger than cast iron?

Compacted graphite iron has 80 percent more tensile strength, 40 percent more stiffness and double the fatigue strength of regular cast iron.

What are the four types of cast iron?

There are four basic types of cast iron – white iron, gray iron, ductile iron and malleable iron

• white iron.
• gray iron.
• ductile iron.
• malleable iron.

What is SinterCast material?

Stockholm-based SinterCast is the developer of a process control package used by foundries to product compacted graphite iron (CGI), a lightweight cast iron that offers greater tensile strength, stiffness, and fatigue strength than gray iron or aluminum.

What is another name for compacted graphite iron CGI )?

vermicular graphite iron
Compacted graphite iron (CGI), also known as vermicular graphite iron (GJV, VG, JV or GGV from the German: “Gusseisen mit Vermiculargraphit”) especially in non-English speaking countries, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron.

Is cast iron pig iron?

Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.

What is compacted graphite cast iron used for?

Compacted Graphite Iron has been increasingly accepted as automotive manufacturing material, showing its efficiency for several components, as brake discs and brake drums, exhaust manifolds, engine heads and diesel engine blocks, traditionally manufactured from gray cast iron (Guesser and Guedes, 1977).

What is the strongest cast iron?

Gray iron is also easier to machine than other cast irons, and its wear resistance properties make it one of the highest volume cast iron products.

Is cast iron GREY or black?

The silicon in grey cast iron causes the carbon to change into graphite. This causes it to have a dark grey or almost black color.

How is compacted graphite iron made?

Foundry Production Similar to ductile iron, compacted graphite iron is produced by adding magnesium to a desulfurized base iron. As shown in Figure 3, CGI is stable over a range of approximately 0.008% magnesium (Mg), which is approximately five times smaller than the commercially used Mg-range for ductile iron.

What is ductile iron made of?

How is Ductile Iron Made? Rather than being cast from iron or steel scrap, ductile iron is made primarily from the crude iron that’s produced by smelting ore in a blast furnace, commonly called ‘pig iron. ‘ Pig iron is about 90% iron with high carbon content, and its chemical properties are very stable.

Is pig iron stronger than cast iron?

(D) Cast iron is soft and malleable while pig iron is extremely hard and brittle. – Cast iron is the iron obtained by melting of the mixture of pig iron and scrap iron and coke by hot air blast. It has around 3% of carbon content. So, it is more pure than pig iron.

What kind of sheet metal can CGI make?

CGI can produce sheet metal assemblies & subassemblies using stainless steel, aluminum, galvanized, cold rolled or hot rolled material from 24 gauge to 0.5” thick. Key equipment runs 24-7 utilizing auto loaders and unloaders. Additional in-house capabilities exist for MIG & TIG welding, spot welding, riveting and fastener insertion.

What does it mean to be a CGI artist?

So you’ve decided you want to be an artist and come across a job listing for a CGI artist. The first question you might ask might be, ‘What does CGI stand for?’ Computer-generated imagery (CGI) is the creation of still and moving images and visual effects using computer hardware and software.

How is CGI used in the real world?

CGI most commonly refers to the 3D computer graphics used to create characters, scenes and special effects in films, television and games. The technology is also used in everything from advertising, architecture, engineering, virtual reality and even art.

What does CGI stand for in visual effects?

CGI stands for “computer-generated imagery.” CGI Artists create still and moving images and visual effects using computers. These images could be anything from characters to environments to special effects.
