text: Aluminum is a good reflector and is therefore applied in solar mirrors and heat reflecting blankets.
text: Aluminum is also a good reflector and a good conductor of electricity.
text: Aluminum is a conductor, and a pretty good one.
text: At frequencies more than 100 MHz, the transmitted electric field is attenuated by more than 80 decibels (dB) (less than 10−8 = 0.00000001 of the power gets through)  -- however actual energy absorption is minimal: the remaining high-frequency rf energy is almost perfectly reflected from uniform flat aluminium surface, and thus, reflected signal may continue to propagate internally, and if holes or passages of suitable geometry exist in the shield, signal propagation may continue out through those, the aluminium being good material for implementation of a microwave-frequency waveguide.[citation needed]
text: Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper.
text: Aluminum is also a good reflector and a good conductor of electricity.
text: Aluminum is a very good conductor of electricity.
