Metal Casting at Home Part 2 Backyard Foundry

In part one I made the sand mould. Now I melt metal and complete the casting.

"Myfordboy".would you know by any chance what aluminum grade soda cans are? 6010...7020

@blazterreck Sorry I don't know the grade only that they are rubbish grade and not worth melting. There is so little metal in them , they produce a lot of dross and the metal is not idea for casting.

Must feel fantastic to make something like that. Excellent job. I'm clueless about metals. I don't understand how the tin you melt the metal in doesn't melt. Just a different metal? I could watch this all day - it's like Christmas when you remove the sand to reveal the mystery of what you made.

@BernhardHofmann The aluminium melts at a much lower temperature than the stainless steel crucible its in.

@blazterreck I am using sodium carbonate: washing soda.

@blazterreck basically anything below 1500 grade is considered "food grade" and has almost no structural properties worthy of a finnished product. Bicycles, cars, airframes typically use 6000- 7000 series aluminum, these have a higher percentage of other alloys such as nickel, zinc, magnesium and a few others. Food grade is basically pure aluminum.
