Fluxing Zinc in the Backyard Foundry bolis

According to the backyard foundry experts, the most useful casting metal that’s even easier to melt than aluminum is zinc. It melts around 420°C/800°F, so you can even melt it on a hot stove. It casts harder than aluminum for better wear, and zinc/aluminum alloys can approach cast iron in strength and durability. Sounds great!get price
