    Yeah this makes no fucking sense, it would be stupidly unnecessarily expensive and also mechanically inferior to make all those parts out of silver.

    Its almost certainly mid to low grade carbon or stainless steel.

    It wouldn’t even make sense to use aluminum… its considerably more expensive than most (all?) steel, and is generally only used when it is critical to maintain strength but also dramatically cut down on weight… aircraft, cars, etc.

    And of course silver is even more expensive than aluminum and steel.

    … Whoever posted this could fairly easily just do a weight vs volume displacement, if they have good scales.

    Silver ~= 10.5 g/cm3

    Aluminum ~= 2.7 g/cm3

    Steel ~= 7.9 g/cm3

    … There could be silver in the circuit board, chips, contacts, something like that… but it not gonna be in … load bearing components… silver is a very soft metal… smdh

      It’s electrical componentry, so conductivity and corrosion are a concern. Differential thermal expansion can also be an issue.

      The lugs are aluminium.

      The split bolts are copper or brass, tin plated for better corrosion resistance.

      None of this is going to be found in a security camera (unless they’ve earthed it with fat conductors for some reason). It’s high power gear.
