i do not understand the price i payed for the scrap aluminium
on the londen metal exchange LME
the price is 2700 usdollar per 1000 kilo
2.7 dollar per kilo
2.7 U.S. dollars = 1.82679296 Euros
1.82 euro * 22 kilo = 40.18euro and i paid 25 euro
could get sleeping rich if i where a scrap metal dealer

An average aluminium can (without its contents)
weighed 16.55 grams in 1992.
By 2005 the aluminium can weighed about 14.7 grams.
thats 68 / 69 cans in a kilo
aluminium can price is 1.5 usd a kilo or 1500usd per ton

so this skull is aprox 345 cans

Aluminium has a melting point of 660°C
compared with 1540°C for iron

If all the aluminium cans sold in the UK were recycled for cash it would raise more than £30 million for collectors.
Setting up an aluminium can recycling scheme is a great way to raise funds for a charity or good cause without having to ask for donations.

Bangladesh Village Metal Casting

Preparing the scrap metal, the furnace and crucibles for casting and explaining a bit about the mould making process. The firing process and casting takes several hours and unfortunately we couldn’t stay. Rice husk is mixed with the clay to make it more refactory. Old crucibles are used to cap the new ones. A combination of brass, copper and zinc is used to make a ‘bell metal’. Both mould and crucible are placed in the furnace, when the metal is molten, both are removed from the furnace, a hole is pierced in the side of the crucible and the metal is poured.
Thanks to Riaz and Britto.

Dhamrai Metal Casting

Foundry Casting of the Michael Myers “Halloween” Tattoo Machine, by 3-D Machines.

Here I show the complete pattern making and casting of a 12 1/16″ flywheel.
Although mainly about pattern making I have also shown the casting so the whole process can be seen.
More detail on the actual casting techniques can be seen in my earlier videos.

Making a cylinder head for a single cylinder hit and miss engine.
Core making moulding casting and machining operations.
The engine is an Olds Gearless, a 4 srtoke with no gears.
An eccentric on the crankshaft operates a ratchet wheel to give the necessary timing.

Making a greensand mould and casting an aluminium cylinder for a model hit and miss engine.

This was an experiment to see if carbon dioxide produced with vinegar and bicarbonated soda could be used to harden a sodium silicate sand core.
The result was a success and is a cheaper alternative to buying bottled CO2.

This casting needed a core to produce the required shape. The core could only be supported at one end so a cantilevered one was used.
