# Tungsten Copper Density

## What is density?

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho). Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.

## What is tungsten copper density?

Tungsten copper density is a property of tungsten copper, it does not changed with the quality and volume, the same tungsten copper content , the density will not changed. Tungsten copper density are only related with content, are unrelated with the mass and volume, different content have different density, but if the same kind tungsten copper, the density are also same.
Tungsten copper density formula: (ρ is the density, m represents the mass, V represents the volume)
When properly understood density formula, pay attention to the special conditions of each physical meaning expressed. From a mathematical point of view, there are three cases:
(1) ρ is constant and V is proportional to m;
(2) m is constant, ρ is inversely proportional to V;
(3) V is constant, ρ is proportional to m.

Combination of physical meaning, only three cases (1) argument is correct, (2) (3) are wrong. Because the density of the same kind of material is certain, it does not vary with the volume and quality varies, so understanding the physics formula, it is impossible from the physical facts, not simply understand the relationship between the amounts of each physical formula from a mathematical point.

## Tungsten Copper Density Units

The tungsten copper density unit is g / cm 3.

## Tungsten Copper Density Applications

Tungsten copper density applications, is reflected in the following aspects.
1. Can identify material objects.
2. Calculate the composition of substances contained in the object.
3. Quality of some difficult to calculate the weighing objects.
4. Calculate the volume of a more complex shape of the object.

## Tungsten Copper Density Detection Method

The basic principles of tungsten copper density testing: ρ = m / V, which are including the following methods
1, Weighing method
2, The proportion Cup
3, Archimedes method
