Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
KappTecZ High temperature, high strength solder that may be used on most metals, but works extremely well on aluminium, copper and stainless steel. It has a high tolerance to vibration and stress, and good elongation for use on dissimilar metals. Above its liquidus of 600 °F, this solder is extremely fluid and will penetrate the closest joints ...
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
Data from the Copernicus Climate Change Service shows global temperature anomalies reached between 1.5 and 1.6 degrees Celsius (between 2.7 and 2.9 degrees Fahrenheit), making 2024 the warmest ...
the heat at which water boils vehemently (the temperature at which water begins to boil is given as an additional value in the description, as 33) 40: melting point of an alloy of one part lead, four parts tin and five parts bismuth 48: 3: melting point of an alloy of equal parts of bismuth and tin 57: 3 + 1 ⁄ 4
