The colour of the light depends upon the metal (lithium(I) gives a magenta red-pink flame, calcium an orange red flame, potassium a lilac flame, strontium a crimson red flame, copper(II) gives a blue or green flame and sodium(I) gives a yellow flame).
Can aluminum get red hot?
Aluminum melts at around 600 C and steel around 1400 C. Molten steel is white hot and molten aluminum red hot. This is colour temperature and nothing to do with the composition. Steel at 600 is red hot too but solid.
Does aluminium burn in fire?
No, all aluminum will burn if it has sufficient oxygen and/or heat. However, a piece of aluminum will not burn hot enough to sustain the combustion. You have to keep supplying it with heat from an outside source, like aircraft fuel.
Does aluminum burn or melt?
Aluminum as a material has a number of properties relevant to its behavior in a fire. Unalloyed aluminum will melt at around 660°C, or 1220°F, but most of its alloys will begin to lose strength at temperatures above 150°C, or 300°F.
Is aluminium flammable?
Aluminum dust is flammable
While aluminum massive blocks or bars have a thin oxide layer which hinders the diffusion of oxygen and thus prevents a chemical reaction that could cause damage, aluminum dust, having a lower surface, tends to heat up and therefore to burn very easily.
Does aluminum burn blue?
When aluminium burns, it produces a white flame. The white colour is due to the intense heat generated during the combustion of aluminium, causing it to emit light across a broad spectrum, including the visible spectrum that we perceive as white light.
What metal burns pink?
The colour of the light depends on the metal: Lithium(I) gives a pink flame, Copper(II) gives a green flame and Sodium(I) gives a yellow flame. This process is used extensively in Chemistry to determine what type and concentration of atoms a substance contains.

Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
What colour does lithium burn?
Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires. It's interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it's the opposite for fire.
What color does rubidium burn?
Cool flame can occur in hydrocarbons, alcohols, aldehydes, oils, acids, waxes, and even methane. The lowest temperature of a cool flame is poorly defined and is conventionally set as a temperature at which the flame can be detected by eye in a dark room (cool flames are hardly visible in daylight).
