Basis and references
Pure metals melt at a point. Alloys melt over a range, from the solidus (where melting starts) to the liquidus (where it finishes). Where the low and high figures below differ, that is the melting range; where they are equal, the source gives a single value.
That distinction matters in practice. Aluminum 7075 has a solidus of 480 °C against 6061's 580 °C, which is why 7075 is far more prone to incipient melting during solution heat treatment and is not practically weldable.
Fahrenheit columns are computed as °C × 9/5 + 32, not transcribed. Elemental rows are cross-checked against CRC values; alloy rows come primarily from engineering property tables.

Notes to the tables
5 notesWhere this data disagrees with itself, with other published charts, or with what the number looks like it means.
Two sources disagree on stainless steel by 60–110 °C. One engineering table gives a single figure of 1510 °C for "stainless steel"; per-alloy data gives 1400–1450 °C for annealed 304. Both rows are shown and labelled. 1400–1450 °C is the correct range for austenitic 304; 1510 °C is closer to a ferritic or martensitic grade, or is a generic figure. Use the grade-specific row, not the generic one.
Chromium carries a genuine 47 °C conflict. One widely used engineering table publishes 1860 °C; the modern accepted value (CRC, IUPAC) is 1907 °C. The 1860 figure is an older measurement that persists in many engineering tables. Both are shown in the row.
Smaller element-level differences are resolved in favour of CRC and noted inline: titanium (1670 versus CRC 1668), nickel (1453 versus 1455), tungsten (3400 versus 3422), molybdenum (2620 versus 2623), manganese (1244 versus 1246) and platinum (1770 versus 1768). All are within about 1% and none changes a process decision, but the differences are recorded because this chart publishes exact numbers.
Alloy rows verified against a second source: 6061 (580/650 °C), 7075 (480/640 °C) and 304 stainless (1400/1450 °C) all matched.
Single-source rows, treat as indicative: aluminum bronze, the brasses, manganese bronze, beryllium copper, cupronickel, wrought/gray/ductile iron, Inconel, Monel, Hastelloy C, magnesium alloys, Zamak, solder, C360 brass and the Ti-6Al-4V solidus/liquidus.
Questions
7 questionsWhat is the melting point of aluminum?
Pure aluminum (1100) melts at 660 °C (1220 °F). Alloys melt lower and over a range: 6061 runs 580–650 °C and 7075 runs 480–640 °C. The alloy family as a whole spans roughly 463–671 °C.
What is the melting point of steel?
Carbon steel melts over roughly 1425–1540 °C (2597–2804 °F), falling as carbon content rises. Annealed 304 stainless melts at 1400–1450 °C. Pure iron melts at 1538 °C.
Why do alloys have a melting range instead of a melting point?
Because the constituents do not all change state at the same temperature. Melting begins at the solidus and finishes at the liquidus, and between the two the alloy is a mush of solid and liquid. Only pure elements and eutectic compositions melt at a single temperature.
Which metal in this chart has the highest melting point?
Tungsten, at 3400–3422 °C (6152–6192 °F). Molybdenum is next at 2620–2623 °C, then platinum at 1768–1770 °C.
What is the melting point of copper and brass?
Pure copper (C110) melts at 1084 °C (1983 °F). Brasses melt considerably lower: free-cutting C360 at 885–900 °C, yellow brass at 905–932 °C and red brass at 990–1025 °C.
Why does 7075 aluminum have such a low solidus?
Its zinc, magnesium and copper content creates low-melting phases, giving a solidus of 480 °C against 580 °C for 6061. That narrow margin below the solution treatment temperature is one reason 7075 is prone to incipient melting and is not practically weldable.
What temperature does solder melt at?
50/50 tin-lead solder melts over 183–215 °C. The 63/37 eutectic composition melts at a single temperature of 183 °C, which is why it is preferred for electronics.
