if you have enough aluminum wire,just buy a recp for aluminum wire.they are about 4$.they have a ground screw.they are made to be used with alu or copper.if you have to use copper,you must use no-ox type grease on the wire before you put on the wire nut.twist wire together add no-ox put on wire nut.or if they have them, get purpple wire nuts from ideal.no-ox already in there.

You would have the two black AL conductors and the new black copper conductor all under the same wire nut. Repeat for white and ground.

Just be aware that alum conductor are larger than copper conductor for the same ampacity so if you have 4.0mm˛ {#12 AWG } Copper conductor then the alum conductor will be 6.0mm˛{#10 AWG] alum so the way you descrbing if you used the purple wirenut and do not fit for some reason and DO not pretwist them keep them straight and use the purple wirenut to get them fit in.

I did check the chart and two 6.0mm˛ alum with one 4.0mm˛ will fit in there.

Just do not pretwist them that why it will not go in.

However there is other option as one of the member here mention a alum rated device they will marked CO/ALR I know it will cost more than standard device but they are rated for alum conductors otherwise a small polairs connector will work.

Or other option I know it will work very well let me paste the photo



If you need more info on this please let me know I will send the link to ya.

Merci.
