Factory selling Alloy Steel to Leicester Factories

here in this lecture we will be learning in detail steel calculation for RCC slabs. and this quit simple. we will just calculate length of all steel bars and then the weight is simple using formula.
thanks for watching.

Can metals be melted in hot water or just by the heat of a human hand?
Some can and in this video I melt a bunch of them!

Here’s where I bought the samples if you are interested in trying this yourself:
(it’s much better in real life than on video

www.crystalgrowing-shop.com (German site, most is available on eBay too)
- Rose’s metal
- Wood’s metal
- Bi-Pb-In-Sn-Cd (in rare cases called French’s metal)

www.smart-elements.com
- cesium
- gallium in vacuum ampoule

www.eBay.com
- gallium
- Field’s metal

The mercury is from antique mercury thermometers.

If you are interested in elements you should check out the rest of his website. His thorium sample is the best I have ever seen!

There are only few sources about the very specialized Na-K-Cs alloy. I have since the making of this video found another source that mentions these compositions and melting points:
12% Na, 47% K, 41% Cs = Melting point -78 C
3% Na, 24% Na, 73% Cs = Melting point -76 C
So no doubt that Na-K-Cs is the metallic alloy with the lowest melting point at around -78 C, but the exact composition is a bit of a mystery…
