= Kinds of Copper alloys *
- http://www.metalreference.com/Forms_Copper_Alloy.html
- Lets make C62500
Composition
- Fe: 3.5 - 5.5 %
- Al : 12.5-13.5 %
- Mn: 0-2 %
- Cu : rest
- Melting point
- Liquidus - 1051 C
- Solidus - 1047 C
- Density : 7.2 g/cm3
Recipes
For 500 cm3 / 3600 g
- Fe : 4% : 144 g
- Al: 13 % : 468 g
- Cu : 83% : 2988
For 400 cm3 / 2880 g
- Fe : 4% : 115 g
- Al: 13 % : 374 g
- Cu : 83% : 2391 g
Preparation protocol
- This is not yet tested : treat as hypothesis
- As we will be using the 500ml graphite crucible for the first time, preheat first to 200 - 300 C, make sure it is stable and dry
Order to actions
- Fe, in as fine as possible form in the crucible
- Al
- Borax
- Wait for it to melt. We expect Iron to dissolve in molten Al
- Stir, check for solid Fe
- Add Cu
- More borax if needed
- heat up to 1200 C, ax the oven can do
- Pour in stailess steel cupcake forms, to form ingots small enough to fit in the crucible
