I like this assortment of butt connectors. They claim to be made of tinned copper.Each connector has good thickness in relation to the gauge of wire that it is meant to connect.My only small issue is that the price is higher than some other connector kits that are available here. But overall this is solid choice for good quality connectors.

One of the advantages of these butt connectors is that they’re a solid tube design instead of a seamed tube design. This design reduces the chance of the crimp loosening over time due to metal fatigue. The thickness of the tubes in this set I would find sufficient for general wiring, but I would want thicker and longer tubing for wiring under lengthwise stress such as a suspended antenna wire. The tin plating on the copper reduces oxidation and tarnish which can adversely affect the quality of the crimped electrical connection.This is a nice kit of general purpose butt connectors. Due to their thin design, I find these ideal for use with single or dual wall heat shrink tubing.
