Foundries that specialize in common casting methods like sand casting usually work in metals chosen for specific qualities such as ease of melting and pouring, detail capture within the mold, predictable behavior while cooling, and readiness for machining or finishing. Alloying iron with other elements in different ratios can mitigate or eliminate one or more of these factors. Hundreds of ferrous alloys are well-known.

They are specified by the proportions of each element in their makeup, as well as directions on their melting and finishing. Ferrous alloys with carbon are usually named iron or steel, and can contain any number of other elements, from aluminum to vanadium, based on their specification. These metals are usually chosen for their mechanical properties. Engineers and designers might be interested in their yield strength, toughness, ductility, weldability, elasticity, shear, and thermal expansion, all of which describe how a material will behave under specific stressors.

These distinctives aspects of iron can be changed in alloys, which mix iron with other elements. Stainless steel is a good example, with some alloys of stainless being both non-magnetic and non-corrosive.

Upcoming Events

A common way of telling if a metal is steel is to put a magnet against it, since the iron in the alloy will cause the magnet to stick; however, people who have tried to stick magnets to their stainless steel fridge know this is not a foolproof test. Though the iron is still present in this ferrous alloy, a high percentage of nickel changes the microstructure of the steel enough to prevent a magnetic reaction.

Stainless steel also does not corrode like other iron alloys and this is thanks to an addition of chromium. Chromium protects against rust through a process called passivation , in which the top molecules of the metal oxidize but stay strongly bonded to the metal below, forming an impenetrable shell.

Guide to Nonferrous Metals

They are relatively inexpensive, dense irons. When they are heated and cast, they have a much higher flowability at lower temperatures than steel, meaning that they can flow into and fill parts of a complex mold with greater efficiency. Cast irons also shrink at half the rate of steel while cooling. Basic cast irons have good compression properties, but they are brittle: they will fracture before they bend or distort. This vulnerability can mean that brittle grades of cast iron are not used for designs with extruding or elaborate details, or with very sharp edges, as these features may chip.

Grey Iron is the most common type of cast iron currently produced, featured in everything from manhole covers to disc brakes on cars. It gets its name from the color it takes upon fracture, which is grey due to the presence of graphite as the carbon additive.

Grey iron is 2. Grey iron is still inflexible: it bends very little before breaking. Ductile Iron is a form of cast iron in which the carbon added is a spherical nodular graphite. Ductile iron is usually 3. Higher ferrite levels mean it builds up on cutting tools during machining, so it is often used in primarily cast manufacture, where very high flowability makes it a great choice for finely detailed work. The spheroid shape of the graphite that gives ductile iron higher impact resistance and tensile strength than either cast or grey iron, making detailed or edged designs feasible.

Ductile iron is a relative newcomer in the specification of irons, as it was first discovered in Steels of all sorts are also sometimes cast. In general, steel has a carbon content of less than 2. Steel has stronger mechanical properties than cast irons, but what is gained in toughness is lost in flowability.

Molten steel needs to be much hotter than molten iron to flow into detailed molds, and the high temperatures required to work with steel are challenging to manage and can handicap the design and finish of the object that comes out of the mold. He has thirteen years of teaching and research experience in the metallurgical field, and has published numerous technical papers in national and international journals. Du kanske gillar.

Non-ferrous grades

This book presents a comprehensive overview of non-ferrous metallurgy, especially its core principles and fundamental aspects, in a concise form. Some non-ferrous metals reflect the CO 2 laser beam so strongly that fiber laser cutting is preferred. This applies for copper cu , gold au and silver ag. For all other non-ferrous metals you can say: fiber lasers mainly have their advantages in thin sheet, but CO 2 lasers mostly have a better quality for thicker material. Aluminum is cut with the help of laser sublimation. Due to the crystal mesh effect of the light metal and due to the wave length of the laser, aluminum is cut technically laborious as the main part of the induced radiation is reflected.

Thus aluminum is preferably cut with the solid state laser. Also other non-ferrous heavy metals such as copper, bronze or zinc can be cut with the laser. Typical tube diameters ranges from1 and 30 mm with a wall thickness of 50 - microns. For this application we recommend: Femtosecond lasers , StarCut Tube. Legal Notice. Privacy Policy.
