What is the melting point of metal? What is the highest and lowest melting point of metal?
A significant issue to be aware of when processing metallic materials is the melting point.
First, let's take a look at what the melting point is.
The melting point of a substance is the temperature at which the solid and liquid phases of the pure substance are balanced under a certain pressure.
That is, at the pressure and temperature of the melting point, the chemical potential of the pure substance is equal to the chemical potential of the liquid.
For the pure material solid system (nanosystem) with large dispersion, the surface part cannot be ignored, and its chemical potential is not only a function of temperature and pressure, but is also related to the size of solid particles, which belongs to thermodynamics. first order phase transition process.
Simply put, only a certain melting point can change the shape of the metal, thus forging different products.
Therefore, we must first understand the melting point of various metals before processing.
Let's dive into the melting point of various ferrous and non-ferrous metals.

In the Periodic Table of Elements there are two non-metallic materials which are silicon and boron, and their melting points are 1420°C and 2300°C, respectively.
What is the highest and lowest melting point?
From the table, we can clearly understand the melting point of various metals.
For the metal with the highest and lowest melting point, I will also give a brief introduction.
There is a type of metal called Cesium, which is silvery white.
It was founded in 1860.
With the exception of mercury, it has the lowest melting point of 29 °C.
Among all pure metals, tungsten has the highest melting point.
In 1783, two Spaniards discovered that the melting point of tungsten was 3417 ± 10 °C.
The most resistant to high temperatures are niobium carbides (TG 0.88) and niobium carbides (HfG 0.95).
The melting points of the two materials were 4010±75°C and 3960±20°C, respectively.
