9. The drilling component of claim 8 , wherein the bore has a diameter of about 2 inches or greater.

10. The drilling component of claim 8 , wherein a sidewall of the component has a thickness of about 1.5 inches or greater.

11. The drilling component of claim 1 , wherein the first female connector extending into the first end of the main body is configured to removably engage a threaded male end of a first drill string component and the second female connector extending into the second end of the main body is configured to removably engage a threaded male end of a second drill string component.

12. The drilling component of claim 1 , having an ultimate tensile strength of at least 160 ksi and a 0.2% offset yield strength of at least 150 ksi.

13. The drilling component of claim 1 , having an ultimate tensile strength of at least 120 ksi and a 0.2% offset yield strength of at least 110 ksi; wherein the elongation at break is at least 15%.

14. The drilling component of claim 1 , having an ultimate tensile strength of at least 106 ksi and a 0.2% offset yield strength of at least 95 ksi; wherein the elongation at break is at least 18%.

15. The drilling component of claim 1 , having an ultimate tensile strength of at least 100 ksi and a 0.2% offset yield strength of at least 85 ksi.

16. The drilling component of claim 15 , having a Charpy V-Notch impact strength of at least 10 ft-lbs.

17. A drilling string comprising:

a first component;

a second component; and

a drilling string component comprising a spinodally-hardened copper-nickel-tin alloy and having a main body with a first female connector extending into a first end of the main body and a second female connector extending into a second end of the main body, wherein the first female connector extending into the first end and the second female connector extending into the second end are threaded connectors;

wherein the drilling string component has an elongation at break of at least 10%;

wherein the drilling string component connects the first component via the first female connector extending into the first end of the main body and the second component via the second female connector extending into the second end of the main body; and

wherein a bore extends through the first component, the second component, and the drilling string component.

18. The drilling string of claim 17 , wherein the spinodally-hardened copper-nickel-tin alloy of the drilling string component comprises from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper.

19. The drilling string of claim 17 , wherein the first female connector extending into the first end of the main body is configured to removably engage a threaded male end of the first component and the second female connector extending into the second end of the main body is configured to removably engage a threaded male end of the second component.

20. A drilling component made from a spinodally-hardened copper-nickel tin alloy and comprising:

a main body; and

a first female connector extending into a first end of the main body and a second female connector extending into a second end of the main body, wherein the first female connector extending into the first end and the second female connector extending into the second end are threaded connectors;
