which is lighter 6061 or 7005
6061 is an alloy that consists of aluminum, magnesium and silicone and is considered to be superior to 7005, made of aluminum and zinc, although the latter appears to be more resistant.xperience has proved that there are indeed differences between 6061 and 7005 alloys but they are hardly to be taken into account. Itâs very unlikely that a usual cyclist will ever put his frame to such pressure that the limits of the two alloys will come into play.
