The trick to shrinking aluminum is to heat the surface of the metal to encourage the molecules to move back into the hot area, thus reducing the size. Considering aluminum does not change colors when it is hot, purchase a temperature crayon at a home or auto body supply shop before shrinking.

Does Aluminium shrink when heated?
How much a material expands when heated is described by its thermal expansion coefficient. For example, aluminum expands 21 to 24 micrometers per meter if you increase its temperature by 1 degree Celsius.
Does aluminum shrink when cold?
When the metal freezes, all the metal shrinks, so the hole gets bigger.
How do you shrink aluminum?
The trick to shrinking aluminum is to heat the surface of the metal to encourage the molecules to move back into the hot area, thus reducing the size. Considering aluminum does not change colors when it is hot, purchase a temperature crayon at a home or auto body supply shop before shrinking.
Does aluminum shrink more than steel when cold?
Aluminum expands much more than steel, when heated. Freezing witll contract the aluminum only to hold the broken race tighter? Try a heat gun or a torch or an iron or something to heat the aluminum. The aluminum will expand (3X) whle the steel will less (2x) and the bearing should come out.
How do you shrink metal with hammer and dolly?
Shrinking metal is a special technique, and there are many ways to do it. The best is to use heat, a wood hammer, and a dolly. Any time you hit sheet metal with steel hammer against a steel dolly, it stretches. Using wood, you eliminate one of those hard points, so the metal can move without stretching.
Do shrinking dollies work?
It hardens the steel and only makes your job worse. Let it cool on its own, then when it only sizzles the damp cloth you can quench it down to feel the panel. * Don’t waste your time with “shrinking hammers” or “shrinking dollies ” They do not work. You will waste both your money and your time.
What temperature does aluminum become brittle?
At temperatures above 400°C, a transition to a brittle-type fracture was observed.
Does freezing metal make it shrink?
When the metal freezes, all the metal shrinks, so the hole gets bigger.
What happens when aluminum is heated?
When the temperature of aluminium is increased, the metal expands and this is called thermal expansion. As a result of the adjustment of the temperature of the metal, thermal expansion of 3 mm is observed.
