Making Cast Iron Bronze - Ingot Give Away

I am making cast iron bronze again with a slightly different method, some crude tests and an ingot give away.

Following on from last weeks video I make cast iron bronze again using cast iron, copper and aluminium but with a slightly different method.

This week I show how I make this cast iron alloy, a aluminium bronze with cast iron and cast it into some 1kg ingots. As I recently reached 1000 subscribers I have 3 of these polished bronze ingots to give away.

The give away video will be later this week.

This is an extremely hard bronze and is well suited to swords, axes, knives, hammers and other similar tools. It should also hold an edge well.
This cast iron bronze has a beautiful golden bronze colour.

The recipe for this weeks cast iron bronze alloy is:
70% Copper
20% Cast Iron
10% Aluminium
Expect losses of 30% to dross as it currently stands.

To make this bronze, melt the copper and the cast iron together, add the aluminium when the copper has melted and mix well, keep heating until everything's melted, skim and pour. Temperatures need to be kept in the 1150C - 1300C range and must be mixed extremely well.

This cast iron copper alloy recipe was provided by Daniele Bosco. You can see his YouTube Channel here    / Канал  
Daniele is from Italy and has studied metallurgy for 5 years.
He has several other recipes for this cast iron bronze which I hope to try out in the future.

Hope you all like this video, happy casting.
