  2. Ductility - Wikipedia

    en.wikipedia.org/wiki/Ductility

    Some metals that are generally described as ductile include gold and copper, while platinum is the most ductile of all metals in pure form. [4] However, not all metals experience ductile failure as some can be characterized with brittle failure like cast iron. Polymers generally can be viewed as ductile materials as they typically allow for ...

  3. Malleable iron - Wikipedia

    en.wikipedia.org/wiki/Malleable_iron

    The ductile to brittle transition temperature is lower than many other ductile iron alloys. In order to properly form the spherical-shaped nodules of graphite (called temper graphite nodules or temper carbon nodules) in the annealing process, care must be taken to ensure that the iron casting will solidify with an entirely white iron cross section.

  4. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    Some nonmetals (black P, S, and Se) are brittle solids at room temperature (although each of these also have malleable, pliable or ductile allotropes). From left to right in the periodic table, the nonmetals can be divided into the reactive nonmetals and the noble gases. The reactive nonmetals near the metalloids show some incipient metallic ...

  5. Ductile iron - Wikipedia

    en.wikipedia.org/wiki/Ductile_iron

    Ductile iron is used in many piano harps (the iron plates which anchor piano strings). Ductile iron is used for vises. Previously, regular cast iron or steel was commonly used. The properties of ductile iron make it a significant upgrade in strength and durability from cast iron without having to use steel, which is expensive and has poor ...

  6. Wrought iron - Wikipedia

    en.wikipedia.org/wiki/Wrought_iron

    Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron.

  7. Metal - Wikipedia

    en.wikipedia.org/wiki/Metal

    While nearly all elemental metals are malleable or ductile, a few—beryllium, chromium, manganese, gallium, and bismuth—are brittle. [40] Arsenic and antimony, if admitted as metals, are brittle. Low values of the ratio of bulk elastic modulus to shear modulus ( Pugh's criterion ) are indicative of intrinsic brittleness. [ 41 ]

  8. Ductility (Earth science) - Wikipedia

    en.wikipedia.org/wiki/Ductility_(Earth_science)

    The brittle–ductile transition zone is characterized by a change in rock failure mode, at an approximate average depth of 10–15 km (~ 6.2–9.3 miles) in continental crust, below which rock becomes less likely to fracture and more likely to deform ductilely. The zone exists because as depth increases confining pressure increases, and ...

  9. Tenacity (mineralogy) - Wikipedia

    en.wikipedia.org/wiki/Tenacity_(mineralogy)

    Ductile materials have to be malleable as well as tough. Sectility. May be cut smoothly with a knife. Relatively few minerals are sectile. Sectility is a form of ...
