Abstract

A copper-nickel-tin alloy contains from about 1.9 wt % to about 21 wt % manganese.

First claim

1 . An alloy comprising copper, nickel, tin, and from about 1.9 wt % to about 21 wt % manganese.

2 . The alloy of claim 1 , wherein the nickel is present in an amount of from about 5 wt % to about 25 wt %.

3 . The alloy of claim 1 , wherein the tin is present in an amount of from about 5 wt % to about 10 wt %.

4 . The alloy of claim 1 , wherein the manganese is present in an amount of from about 1.9 wt % to about 10 wt %.

5 . The alloy of claim 1 , wherein the manganese is present in an amount of from about 1.9 wt % to about 5 wt %.

6 . The alloy of claim 1 , wherein the manganese is present in an amount of from about 1.9 wt % to about 2 wt %.

7 . The alloy of claim 1 , wherein the manganese is present in an amount of from about 2 wt % to about 10 wt %.

8 . An article comprising a copper-nickel-tin-manganese alloy, wherein the manganese is present in in the alloy in an amount of from about 1.9 wt % to about 21 wt %.

9 . The article of claim 8 , wherein the article is selected from the group consisting of a bushing, an instrument housing, a connector, a centralizer, a fastener, a drill collar, a mold for plastic shapes, a welding arm, an electrode, a cast component, and a certified ingot.

10 . The article of claim 8 , wherein the article is a strip, a rod, a bar, a tube, or a plate.

11 . The article of claim 8 , wherein the alloy comprises from about 5 wt % to about 25 wt % nickel and from about 5 wt % to about 10 wt % tin.

12 . The article of claim 8 , wherein the article has at least one dimension in excess of about 5 inches.

13 . A method for producing an article, comprising casting a copper-nickel-tin alloy that also contains 0.2 wt % to 21 wt % manganese to produce the article.

14 . The method of claim 13 , further comprising cold working the article.

15 . The method of claim 13 , further comprising precipitation hardening the article by heat treatment with or without cold working.

16 . The method of claim 13 , wherein the nickel is present in an amount of from about 5 wt % to about 25 wt % of the article; and wherein the tin is present in an amount of from about 5 wt % to about 10 wt % of the article.

17 . The method of claim 13 , wherein the manganese is present in an amount of from about 0.2 wt % to about 10 wt % of the article.

18 . The method of claim 13 , wherein the manganese is present in an amount of from about 0.2 wt % to about 5 wt % of the article.

19 . The method of claim 13 , wherein the manganese is present in an amount of from about 0.2 wt % to about 2 wt % of the article.

20 . The method of claim 13 , wherein the manganese is present in an amount of from about 0.2 wt % to about 1.9 wt % of the article.
