The Melting Point of Ferrous Metal and Nonferrous Metal

For the metal with the highest and lowest melting point, I'll also give you a brief introduction. There is a kind of metal called Caesium, which is silvery white. It was found in 1860. Except for mercury, it has the lowest melting point of 29 C. Among all pure metals, tungsten has the highest melting point. Get price

Sodium

NaK with 77% potassium is eutectic and has the lowest melting point of the NaK alloys at −12.6 C.

Melting Points of the Elements

*Melting Point Notes: 1. At normal atmospheric pressure carbon does not melt when heated, it sublimes. i.e. when heated, carbon undergoes a phase change directly from solid to gas. If the pressure is increased to 10 atmospheres carbon (graphite) is observed to melt at 3550 C. 2. Get price

Pour me a mandrel

Low-melting-point alloys have the advantage of conforming to any tube or pipe diameter, as well as any irregular shape, because they expand upon cooling rather than shrink. Because the alloys completely fill the tube or pipe during bending, the tube can be bent smoothly without kinking or wrinkling. Get price

Melting Point, Density, and Reactivity of Metals

Aug 01, 2001The density and melting point of a metal, taken together, can give a useful qualitative guide to the chemical reactivity of the metal. A high density and high melting point indicate a low reactivity; conversely, low density and low melting point indicate high reactivity. The melting point is allied to the heat of sublimation; the density gives a guide to the magnitude of the ionization energy. Get price

The Melting Point of Steel Alloys

As reflected by the median melting points of "low" alloy steel which is 1436 OC (2610 OF) and high allow steel which is 1415 OC (2600 OF). On its own, pure iron (Fe) has a melting point of 1535 OC, so alloying it decreases its melting range as explained above. Get price

Melting Point of Metals Alloys

Melting Point of Common Metals, Alloys, Other Materials. What is a melting point?

Low melting point alloys their uses

Indium is added to the alloy in order to give it a considerably lower melting point. Lens alloys are eutectic alloys, characteristically possessing a sharp melting point at 58 or 47 degrees Celsius. This low temperature is ideal for acting as a 'button' or holding medium in the grinding of lenses. Get price
