Advantage of Aluminum vs Copper wiring in power tools
 
I have noticed that some products; bench grinders and drill presses as an example, have started using aluminum wiring in their motors instead of copper. Is there an advantage to having aluminum wiring? Or should I avoid products with this type of motor?

I understand about wiring in houses, I am more interested in aluminum wiring use in motors of tools.

Thank you

I have never seen a tool with aluminum wire in it. Can you be more specific as to what brand you are talking about?

I was told by a saleman at Depot that some of the Ryobi tools (bench grinder and drill press) were now using Aluminum wiring

Back in the 60's GE built double engined U50C diesels for the Union Pacific railroad with aluminum wiring instead of copper wiring! The aluminum wiring was a nightmare and was prone to overheating! The locomotives were scrapped after only a couple of years of service! Google GE U50C and read Wikipedia's page!

I'll have to research these tools out for myself, I knew they made aluminum transformer windings for many years, but not consumer grade tools. Makes sense though- aluminum is a lot cheaper, that way they can charge the same as before but make more money!:laughing:

I don't believe there would be a problem if everything is designed correctly, only thing I am thinking of is if they want to use the absolute cheapest motor possible, what else in the tool are they scrimping on?

This is just my personal view and I have nothing to back it up but , I would stay away from anything new that has aluminum wiring in it till it becomes proven that it lasts. I have tools that I bought when I started in carpentry like my 35 year old Rockwell Tiger Saw (reciprocating saw, or sawsall). It cost me a pretty penny when I bought it, but time has proven it's worth.
