Tantalum bolts are best known for its unmatched corrosion resistance and chemical inertness. Tantalum bolts have a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal.Tantalum bolts are also extremely stable at high temperatures, since tantalum has a melting point around 3000°C.

Lithium - Study Material for IIT JEE | askIITians

The melting point and boiling point of lithium are comparatively high. Lithium is much harder than the other alkali metals. Magnesium is also hard metal. Lithium reacts with oxygen least readily to form normal oxide whereas other alkali metals form peroxides and superoxides. LiOH like Mg (OH)2 is weak base.

For customers purchasing their products in bulk quantity, the good news is that the starting prices of the 500kg electric ARC furnace silicon chromeSiCr alloy melting are from 21,505-143,369 with Qingdao as delivery port and the minimum amount to order the 500kg electric ARC furnace silicon chromeSiCr alloy melting …

Aluminum 3D Printing Material Information - Shapeways

The support is then removed and polished away from the part during post-processing. Selective laser melting is unique because the high power laser provides enough energy to heat the aluminum powder above the melting point. This process fully melts the powder rather than just sintering it, creating a solid, homogeneous aluminum alloy.
