What is the thermal conductivity of Cast iron?
Thermal conductivity refers to the measure of the ability of a material to allow the flow of heat from its warmer surface to its colder surface. The thermal conductivity of cast iron is 80 Wm-1K-1.
Can you conclude anything about the thermal expansion rates of iron and brass?
Brass expands roughly 1.6 times more than iron when heated to the same temperatures.
What are the Rates of expansion and contraction of cast iron and steel and brass and cpvc pipe?
The coeifficent of expansion per degree can be found in the manufacturers charts
Which material used to make a lathe bed?
Cast iron is used as the "material of choice" for many machinery housings or bases because it is extremely stable in its structure. Certainly it is subject to thermal expansion and contraction, but the crystal structure of cast iron makes it "hold its shape" in applications ranging from machines and machine parts to cookware. And in things like a lathe bed, we need the thing to be "the same" every day and all the time so we get accurate, consistent work. Cast iron also suppresses high frequencies generated during machining. Note that the ways (the parts of the bed that the carriage slides on), are hardened and machined to provide lasting and accurate surfaces.
What is the thermal expansion coefficient for iron oxide?
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
When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?
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

Why the diameter of iron rim round a tanga wheel is made slightly smaller?
it is due to thermal expansion

Does aluminum expand twice as much as cast iron?
Linear Coefficient of Expansion.Heating a metal to temperatures below its melting point causes it to expand or increase in length. If a bar or rod is uniformly heated along its length, every unit of length of the bar increases. This increase per unit length per degree rise in temperature is called the coefficient of linear expansion. Where a metal will be alternately subjected to beating and cooling cycles and must maintain a certain tolerance of dimensions, a low coefficient of thermal expansion is desirable. When in contact with a metal of a different coefficient, this consideration assumes greater importance.Titanium has a low coefficient of linear expansion which is equal to 5.0x10-6inch per inch/°F, whereas that of stainless steel is 7.8x10-6, copper 16.5x10-6, and aluminum 12.9x10-6.copied fromhttp://www.keytometals.com/ARTICLE122.HTM
Why does an iron wire expand when heated?
That's not just an iron wire - most materials expand when heated. This is called thermal expansion, and has to do with the fact that molecules move faster when it is hotter.
