RotoMetals Low-Melting Point 158F Alloy Ingot

I used this product to do chamber cast on Swiss vetterli rifles.It melts with a grill lighter and is easy to use.

As a gunsmith... This is a must have to check and cast Caliber....

I carved a wax heart, embedded it in plaster of paris, put the casting in the microwave to get the wax out, then poured this metal into the sprue hole. Voila! Instant metal heart! My 7 year old daughter was impressed so much that she didn't even realize she had learned how to do lost wax casting. I had fun also. This stuff melts at 158 degrees F, so is easy to work with and not dangerous at all (does contain lead, so wash hands and don't chew on it). One nasty problem is that it will attack all but the best stainless steels, possibly even gold or silver jewelry, so be careful! There is a more expensive version that contains no lead and I think melts even lower. maybe I'll get some and experiment.

Worked perfectly for my application. Stuck case removal in a rifle chamber.

Do not use this product to cast a chamber in a firearm. It was very hard to remove from chamber.it does melt easily though. The product that was recommended to me from a gunsmith was cerrosafe for casting chambers. Hopefully I can find another use for it

I have a lot of options with this to harden most metals. I am Conan. I am going to make a modern era broadsword. To gleam in the sun eternal without tarnish.

received shipment promptly from seller. This stuff is awesome for cub scout pinewood derby cars. I remember my dad having some 30 years ago. It does contain lead, so i melted it in a double-boiler config in a disposable alum loaf pan in a pot of water on the stove. Poured it into cold water and got nice small nuggets of metal. After the car was complete, i added weight to get to the max spec for the derby and re-melted it and poured it into a small vessel for attachment to the car. WAY cheaper than buying steel weights at the scout shop or at the bigbox hardware store. Thanks for making this out-of-the-way product available.

I used my 3D printer to print a heart then made a silicone mold from that. I poured the Bismuth into the silicone mold to make a metal cast heart. The cast Bismuth was full of pot marks but that ended up making it even better. I'd love to figure out how to cast it without getting the bubbles. I poured some onto a dinner plate and when I pulled it off the surface was reflective smooth so I know its possible.I like it because you can make metal parts without the danger and hassle of very high temperatures.
