The tracer bullet consisted of a cupronickel shell, the nose of which contained a leaden core to balance the bullet properly. |
As soon as the cupronickel jacket strikes the armor plate it splits and the lead core flattens out and flies into fragments. |
Our armor-piercing bullet was made with a cupronickel jacket for the sake of the gun barrel. |
This would have been copper, silver, or gold-not the modern base-metal alloys like cupronickel, aluminum-bronze, and copper-plated zinc. |
While many types of resistive metal foils are available for the construction of flexible heaters, the most common types are cupronickel, constantan, Inconcl and aluminum. |
In rifle and machine-gun bullets, a soft core of lead is encased in a harder jacket of steel or cupronickel. |
