Alloying bronze for casting

Mr. Binnion,

Thank you for this detailed

I have purchased the bronze alloy (510) from McMaster Carr in sheet
form. I have fabricated an anticlastic bangle bracelet in 22 gauge.
It has formed nicely using my anticlastic stakes. The 510 alloy
contains 93.4-95.3% copper, 0.3% zinc, 0.05% lead, 4.2%-5.8% tin,
0.10% iorn, and 0.03-0.35% phosphorous. Should I be wearing gloves
as I fabricate this metal because of the lead content? Also, should I
use different files for this alloy so as not to contaminate other
metals? Thank you for sharing your extensive knowledge.
