melting point

“What temperature does this metal melt at?”

This is one of the most common questions we get asked. And depending on your project, this might make a huge difference. If you are trying to melt metal, this is obviously important. But also, when your project exposes metals to high heat, you need to know what the melting points are for your materials.

As a general rule of thumb, alloys with iron, such as steel or pure iron, melt at higher temperatures, typically around 2200-2500 Fahrenheit. Copper alloys, such as brasses, bronzes, or pure copper, have high melting points but significantly lower than iron. Typically at ranges around 1675-1981 F. Aluminum and metals alloyed with aluminum melt at significantly lower temperatures. Pure aluminum melts at about 1218 F, but other metals can raise this.

On the high end of extremes you have Nickel and Tungsten, both of which melt at very high temperatures. Nickel melts around 2646 F, Tungsten around 6150 F, yes you read that number correctly. At the lower end is lead, which melts at the relatively low temperature of 621 F.

Also, the melting point of metals is actually more complicated than you’d imagine. There isn’t a set temperature where a metal melts. Rather, there is a range going from Solidus to Liquidus. As you might guess from the names, this is the range from when the metal is totally solid to totally liquid.
