It depends on the mixture and the propellant in the can. Old style cans with CFCs and modern nitrogen pressurized cans have nonflammable propellants. Cans which have water based contents have nonflammable contents. Cans containing propane or similar propellants and or hydrocarbon contents would of course be flammable.
The biggest problem is not however their flammability.
In a fire situation the can and its contents over pressure as the can heats up until the can ruptures (not explode). The contents vaporize instantly due to the sudden drop in pressure. If the contents and or propellant are flammable this mass of vaporized flammable gas detonates or deflagrates in a process known as a BLEVE (Boiling Liquid Expanding Vapour Explosion) which either sends a ball of burning gas through the area and or sends shreds of ruptured can through the area (both cases are unpleasant)
If the contents and propellant are not flammable the can can still be projected by the rupture either as shrapnel or as a rocket powered can, and the gas can blow the initial fire all over the place
The value chain of aerosol cans is all about supply and demand. Aerosol cans are necessary for most jobs that require spray paint, or cleaning supplies. The value will depend on what product is being used in the cans.
Many aerosol cans use a propellant under pressure to disperse the contents of the can. These propellants are ofter flammable. If incinerated with some of this flammable propellant still in the can they would explode.

no but my bottom does
of course
They don't have to be in a cabinet. Some people store there aerosol cans in hollowed out TV sets and some people bury them in the ground in treasure chests. I keep my aerosol spray cans in a locked box hidden in my attic, so they will never be stolen.

Aerosol has fumes that are very flammable. Throwing it into a fire, that is creating a bomb, literally.
CFC is the abbreviation. This abbreviation is often seen on aerosol cans. Hairspray brands such as Aqua Net in the 1980s had large aerosol cans with that abbreviation on the label.
We will also ban the sale of aerosol paint cans to children under the age of 16.
chlorofluorocarbons (CFCs)
Aerosol spray cans were invented by Lyle David Goodloe and W. N. Sullivan in 1941.
