Constantan is a variation of cupronickel
with 55% copper and 45% nickel and a resistivity of 19.
Using harder tube materials such as cupronickel
and titanium can allow higher velocities to be used without much erosion.
12) Figure 1 clearly shows what happened in 1965, when its composition was changed from silver to cupronickel
and silver coins, which are both larger than a 50p coin, will sell for pounds 9.

In 1919 DuPont reduced cupronickel
fouling in rifles by incorporating tin in granules of early Improved Military Rifle (IMR) powders, denoted by adding "1/2" to the powder number.
The demand for the new 10, 20 and 50 cent coins has been much higher than for the earlier cupronickel
fouling built up so thickly inside the bore some barrels eventually split from the pressure, so groove diameter was deepened to 0.
