The aluminum resistor is characterized in that an aluminum housing is arranged outside the electrical heated tube resistor. The manufacturing process comprises the steps of: tightly jointing all parts inside the electrical heated tube resistor after the electrical heated tube resistor is subjected to a pipe shrinkage process; and then placing the electrical heated tube resistor in a mould, adding molten aluminum for one-step forming to ensure that the aluminum housing is wrapped outside the electrical heated tube resistor to obtain the aluminum housing resistor. The aluminum housing resistor is high in production efficiency, low in rejection rate, low in surface temperature after being electrified, good in impact resistance, low in surface temperature and long in impact service life.
