Dan...Look at tha warning label sent with the Berylalloy parts. Yes
berylalloy is less toxic than the pure metal, but it is no less toxic and a
danger to the man doing the work without a protective mask.

>> Hey guys,
>>
>> As some of you will recall, I built my large coil's primary from bronze
>> weather-stripping based on Terry Blake's design. I'm noticing the issues
>> that several list members warned me about. The extra resistance of the
>> bronze is causing it to get rather hot. This is in turn causing the foam
>> tape used as a winding spacer to melt, not to mention the energy being lost
>> to it.
>>
>> I ordered some copper ribbon to replace the bronze but when I
> received it, I
>> noticed it had a gold color similar to the bronze I already had. I called
>> the seller and asked about it and he told me that it was actually an alloy
>> known as C170 copper which is a Beryllium Copper Alloy. He offered to allow
>> me to return it if needed.
>>
>> What do you think about this alloy? Anyone using it? Should I return it and
>> look for 100% copper?
>>
>> Thanks,
