The CTE of Silica depends on it's state. Crystalline Silica has a much higher Coefficient of Thermal Expansion than fused - or glassy silica. Crystalline Silica CTE is dependent on the axis along which a single crystal in mounted. Along the z-axis CTE is as high as 12 x 10^-6 / degree C. Perpendicular to the z-axis CTE is 20 x 10^-6 / degree C (range ambient to 550C). Amorphous Silica CTE is listed as 0.55 x 10^-6 /degree C
For the elemental metals, you can use the link below to see a chart of their coefficients of thermal expansion (CTE). If you are interested in the CTE of various alloys, a link is provided to allow you begin to search. There are hundreds of alloys, and with many of them, the slight difference in formulation leads to only minuscule changes in the CTE.
Linear expansion coeficient 10.5 to 11.6 parts per million per kelvin. Depends on kind of steel.
Example: 1000.000m steel rod, add 1K of temperature, you get 1000.010m
It's 8.6x10-6 K-1 (or 4.8 x10-6 oF-1 if you're not using SI).

It is around 4.9 x 10^-6/C at room temperature, depending on grade, but thatis a pretty good number to use.
7-12 X10-6 per K depending on the type of oxide (up to about 600C). At higher temperatures, the coefficient ranges from 12-18X10-6 per K. This is based on a paper published in Japan around 2009.
It's over 9000!
10.8 x 10^-6/K
Brass expands roughly 1.6 times more than iron when heated to the same temperatures.
Iron Oxide or rust
Iron is not a carcinogen. Iron is a mineral which can be found in a human body. Even iron oxide is not a carcinogen.
That is the chemical formula. The name would be iron (III) oxide, or ferric oxide in the old system.
10.8 x 10^-6/K
Rusted iron is not pure iron; it is an iron oxide.
The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion
This reaction is:Al + Fe2O3 = Al2O3 + Fe
it is due to thermal expansion
Iron Oxide Its actually Iron(ii) Oxide there is no such thing as iron oxide.
Rust is not an element but compounds of iron. The brown oxide of iron is ferrous oxide and the black oxide of iron is ferric oxide.
No, iron oxide is a solid.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
The scientific name for rust is iron oxide. It is made up of the elements iron and oxygen. Turning iron to iron oxide is an example of corrosion.
