Brass and Iron
The thermometric substance in a bimetallic thermometer is the two metals that are bonded together to form the bimetal strip. Typically, one metal will expand more than the other when heated, causing the strip to bend and indicate the temperature.
The two heavy metals that make up Earth's core are iron and nickel. They are believed to be primarily responsible for the Earth's magnetic field.
Iron and nickel.

The two main elements that make up most of Earth's core are iron and nickel. These heavy metals are believed to be the primary components that give the core its dense and solid nature.
The outer core is a layer of the Earth, the second to last layer. It creates the Earths Magnetic field by moving around the inner core. There are two metals that make up the outer core, these two metals are iron and nickel. The inner core is so hot that it melts the nickel and iron turning it into liquid magma.
The two most abundant metals found in the Earth's crust are aluminum and iron. Aluminum is the most abundant metal, making up about 8.1% of the Earth's crust, while iron is the second most abundant, making up about 5.0% of the Earth's crust.
