Answer: LOK Brand connectors are considered high copper content (no less than 68% copper) brass. This is a higher copper content than most connectors. The bulk of the remaining content is zinc and by definition brass in an alloy of copper and zinc. Additionally, the plating we apply is also significantly heavier than most of the competition.
While any higher copper content is obviously a good thing sonically, it makes machining the connectors extremely difficult due to the softness of the metal. It also limits the durability of use in your system. Just to give you an idea of where we stand, my understanding is that WBT toplines also use a 68% copper content brass.
