The metals handbook defines hardness as "Resistance of metal to plastic deformation, usually by indentation. However, the term may also refer to stiffness or temper or to resistance to scratching, abrasion, or cutting. It is the property of a metal, which gives it the ability to resist being permanently, deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. In mineralogy the property of matter commonly described as the resistance of a substance to being scratched by another substance. In metallurgy hardness is defined as the ability of a material to resist plastic deformation.

The dictionary of Metallurgy defines the indentation hardness as the resistance of a material to indentation. This is the usual type of hardness test, in which a pointed or rounded indenter is pressed into a surface under a substantially static load.

Tungsten Copper Hardness

Tungsten copper hardness is how much? Tungsten copper hardness of different grades does the same? What is the definition of tungsten copper hardness is it? First is what we say it is the hardness of tungsten copper. The so-called tungsten copper tungsten copper hardness refers to resist a hard object pressed into the surface of its capabilities. So know what hardness of tungsten copper, and then we understand under the classification of tungsten-copper alloy. Tungsten copper material is an electrician, but also instantaneous high-temperature materials, of course, also is used as armor material. Tungsten copper is used for electrical materials, can be divided into electrical contact materials and electrical processing materials.

Mentioned a variety of hardness, then the tungsten copper are used which kinds of hardness?
Common types of tungsten copper hardness: the hardness of tungsten copper is used for Brinell hardness (HB) or Rockwell hardness (HR).
Brinell hardness of tungsten copper advantage: the measured value is stable, accurate, and can truly reflect the average hardness of the material.
Brinell hardness of tungsten copper drawback: the indentation greater operating slowly, NA production of finished parts and thin pieces.
Brinell hardness measurement range: raw materials and semi-finished products for hardness measurements can be used to measure iron; non-ferrous metals (non-ferrous), lower hardness of steel (such as annealing, normalizing, quenching and tempering of steel).
Advantages of tungsten copper:: Rockwell hardness measuring rapid, simple, small indentation hardness measurement range.
Disadvantages Rockwell hardness of tungsten copper: the data accuracy, stability, repeatability is better Brinell hardness.
Rockwell hardness measurement range: can be used for finished products and thin pieces, but not coarse uneven material measuring tissue.
Tungsten copper hardness units and symbols: Brinell hardness of tungsten copper units - kgf / mm2 (N / mm2), tungsten copper Brinell hardness symbol is HB; numerical tungsten copper Rockwell hardness of no units and tungsten-copper alloy Rockwell hardness symbol is HBS.

You can also convert between hardness of. So we say that the conversion method under tungsten copper hardness:
A Shore hardness (HS) = Bo hardness (BHN) / 10 + 12
2, Shore hardness (HS) = Rockwell hardness (HRC) +15
3, Bo hardness (BHN) = Lockean hardness (HV)
4, Rockwell hardness (HRC) = Bo hardness (BHN) / 10-3
Hardness test range
HS <100
HB <500
HV <1300
