(ᴬIn determining copper minimum, copper may be calculated as copper plus nickel.
ᴮIt is possible that the mechanical requirements of copper alloy UNS No. C94700 (heat treated) will not be obtained if the lead content exceeds 0.01 %
ᶜNiobium 0.10–0.30 %, boron 0.001 % max, bismuth 0.001 % max, magnesium 0.0005–0.15 %, and titanium 0.01 % max)
