Injector washers

[Hasdrubal]

Ordered a set of injection washers from a CUCV parts place for my upcoming new injector install. They are aluminum, I was under the impression that that they are supposed to be made of annealed copper. Diagram showed they are washers for injectors, part #14025557 on package is correct. Can I use these, is there any drawback or should I get a set of copper ones.

I don't know why it would make a big difference either way. Drain plug washers and spark plug washers come in aluminum on cars using these. Don't know why injector washers would be any different. Just a soft metal to seal.
