31-8-2009A metal is a solid Like all solids if you heat it to a high enough temperature it will melt like ice melts at 32F A high melting point means that this melting temperature is rather high (compared to other metals) For instance lead is an example of a metal with a low melting point: 600 F or so so you can melt it without specialized equipment

Nonferrous metals do not contain any iron or metals that have an insignificant amount used as an alloy Nonferrous metals are nonmagnetic Standard nonferrous metals are aluminum copper lead nickel tin and zinc and their alloys Nonferrous metals have lower strength at high temperatures and more shrinkage than ferrous metals

Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons The attraction between the metal ions and the delocalised electrons must be overcome to melt or to boil a metal These attractive forces are strong so metals have high melting and boiling points

Deposition of high melting point (refractory) metals like Niobium Tungsten Rhenium Tantalum or Molybdenum can be a complicate task to be accomplished with e-beam evaporators The little melting temperature difference between the crucible and the contained evaporation material can lead to various kind of problems and defects like: overheating of the crucible and

The alkali metals have low melting and boiling points compared to most other metals Apart from the other alkali metals only three metals (indium gallium and mercury) have lower melting points than lithium You can see from the graph that lithium at the top of Group 1 has the highest melting point in the group

Firstly these metals differ in physical properties because they all belong to different groups The main characteristics and applications of these metals are somehow linked with their high resistance For most metals the melting point is around 200 degree Celsius whereas for refractory metals the melting point is more than 1500 degree Celsius

Pyridine has a lower symmetry than benzene hence its lower melting point but the melting point again increases with diazine and triazines Many cage-like compounds like adamantane and cubane with high symmetry have relatively high melting points A high melting point results from a high heat of fusion a low entropy of fusion or

Metals are hard because the attraction between both the ions is very strong The attracting force which hold the ions together is very strong Thus they are very hard As they have strong attracting force they have high melting point as they do not loose each other easily That's why metals are hard and have high melting point

High-melting-point metals and alloys can only be deposited by high-pressure cold spray systems since a higher particle velocity is needed in order to generate sufficient plastic deformation of the material due to the lower temperature of the jet compared to other thermal spray techniques
