Saturday/ brass, copper and aluminum

Brass, copper and aluminum, from the bottom up. The big cubes are 3 x 3 x 3 cm (3 cm is a little over an inch).

Here’s another ‘souvenir’ acquisition I made in Japan – these from a hardware store called Tokyu Hands in Tokyo.  (I have a little thing for pure metal objects or ingots). The cubes and cone casts are made of brass*, pure copper and pure aluminum.  I think these are made available for science class in schools, more than anything else.  There was a pure lead ingot for sale as well, but lead is poisonous and I did not want that in my house.

*Brass is basically an alloy of copper and zinc.  Some types of brass alloys have small amounts of tin, aluminum, nickel or iron added in as well.
