      It depends what you mean by the suns heat. The hottest part of the sun is the plasma around the outside, this reaches for millions of miles into space and reach up to 3 million degrees Celsius! So no metal, or any liquid or solid could withstand that heat. If we somehow got past that to the surface of the sun, it is ‘only’ around 5000 degrees Celsius, so some liquids could withstand the heat, but not metals I don’t think.

      Tungsten has a melting point of 3422 deg Celsius! It will start to boil around 5500 deg Celsius, which is about the outer surface temperature of the sun. Maybe not so good for building a satellite to go to the sun, but good for use in lightbulbs!
