Doing a bit more lost wax casting, this time making a custom hood ornament for a 1927 model T. Im not 100% happy with the casting and will be repouring it, but without the added concern of making a video..
I thought there was nickel in it, and that the nickel was the whitener, but they are not stating that here... https://www.riogrande.com/Product/Casterrsquos-White-Bronze-Chunks/706013 Likely several different formulations to create a white bronze. I like the one i posted above (although expensive comparatively) but it casts easily, virtually no fire scale, low melt temp....
I'd like to learn more about casting copper alloys, namely bronzes. Might be good for those in the know to start a thread about the typical casting alloys, their properties, benefits, casting practice, and where they are best applied. Best, K
the sds sheets on Riogrande lists the % of metals in the alloy. this white bronze has 15/20% Mn I expect that is the whitener...
Manganese is also found in ordinary silicon bronze. Just a tiny amount. I won a T-shirt of "the dirty smith" because I knew that. He made a mistake in a video and said magnesium. I get the two confused myself... Mn vs Mg
Throw some Mg into a pot of molten bronze and let us know how it goes! David-how corrosion resistant is the white bronze? Robert
Depends on how much and how fast you get it under the liquid bronze. Too much too slowly..... step back and watch the light show
What pour temperature do you use? I'd like to play with something like this down the road, but not sure my electric furnace is up to the task. I know it will make it to 1600f, in theory they will make it to at least 1830. But how well that heat transfers to the melt.... ?
David, That's a cool looking part and it belongs on a roadster or other classic car. Thanks for sharing. Bill
