What is the luster of arkose on the mohs scale for hardness?
Arkose typically has a luster ranging from dull to earthy due to its composition of quartz, feldspar, and other minerals. On the Mohs scale of hardness, arkose has a hardness of around 6-7, depending on the specific mineral content and composition.
What term refers to the resistance of a mineral to scratching?
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
What is aluminium's hardness?
Aluminum oxide, as corundum, defines 9.0 on the Mohs hardness scale.
What is the hardness of Flint according to the mohs scale of hardness?
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
What is the hardness of dolomite on the MOHS hardness scale?
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
Elements described by their hardness shininess and ductility is what?
metals
What is the relationship between hardness and ductility?
when ductility increase hardness decrease
Opposite of ductility?
Hardness is the opposite of ductility.
List four properties of most metals?
Good conductors of heat and electricity. Malleable and ductile, meaning they can be easily shaped and stretched. Reflective, often having a shiny appearance. High melting points and densities.
What is the aim of the producer?
alloying elements can be added to lower cost improve properties - it could be hardness, toughness, ductility, conductivity, corrosion resistance, pitting resistance etc
What is the property of ductility?
Ductility is "The ability to bend or flex". Stiffness, rigidity, and hardness come to mind. If a metal is hard it isn't Ductile.
What is the aim of producing alloys?
alloying elements can be added to lower cost improve properties - it could be hardness, toughness, ductility, conductivity, corrosion resistance, pitting resistance etc
What six examples of physical properties?
Color, mass, volume, density, hardness, and ductility
How hard are brass alloys?
Brass alloys vary in hardness depending on their composition and processing. Generally, brass is known for its good machinability and moderate hardness, which can be enhanced through cold working. The addition of elements like zinc, aluminum, or tin influences its hardness, with certain brass alloys achieving a hardness comparable to steel. Overall, brass alloys are versatile, balancing strength and ductility for various applications.
What is the typical effect of the addition of an interstitial element on the properties of a metal?
Increase in hardness and strength, decrease in ductility.
Is boron ductile?
No, boron is not ductile. It is a brittle element and known for its hardness rather than ductility.
What are the physical properties that can cause change to a metal?
Examples: melting point, ductility, malleability, hardness etc.,
