So, lots wrong here.
Speaker terminals have voltage, and accidentally shorting them can damage your amp. You don't want long, conductive terminals here. Next, they look very hard. You want your spades to be soft, that improves how well they grip and stay put.
In terms of affordability, get some crimp on spades made of copper and use appropriate heat shrink to insulate them below the spades. Something like this will work. Of course, check your wire guage to be sure you get the right size:

Hey to these is that the core is copper. Copper is a great conductor and very soft.
