so a better design/type of resistor, even with the same resistance value can handle greater power ? with these cement resistor being the cheaper and less capable end of the resistor types ?
Resistors are manufactured in different models that vary all over the map in rated power dissipation.
Naturally, high-power resistors are physically larger than lower-power units.
"Cement" resistors are at the cheap end of the range for high-power wirewound resistors, but each model has a specified maximum power.
Where it gets tricky is that the manufacturer may specify the maximum power under different conditions for different models.
Leaded resistors are usually specified at a given ambient (air) temperature, but metal-cased resistors are specified at a given case temperature, since they are intended to be screwed down to a metal heat sink.
As a rule of thumb, it is a good idea to keep the power dissipation in a leaded resistor below 1/2 its rated power.
Legitimate manufacturers will post a data sheet online with full specifications.
At 1/8 ohm, Mouser has 10 W and 25 W models in their search engine.
At 0.120 ohm, they have 1, 2, 3, 5, 7 W, jumping to 200, 300 W, and 994 W (interesting).
Here is the manufacturer's data for a 300 W resistor:
