A process for producing a copper-beryllium alloy product. The process comprises preparing a base alloy having 0.15 wt %-4.0 wt % beryllium and having grains and an initial cross section area. The process further comprises cold working the base alloy to a percentage of cold reduction of area (CRA) greater than 40%, based on the initial cross section area, and heat treating the cold worked alloy to produce the copper-beryllium alloy product. The grain structure of the copper-beryllium alloy product has an orientation angle of less than 45° when viewed along the direction of the cold working. The copper-beryllium alloy product demonstrates a fatigue strength of at least 385 MPa after 10cycles of testing.

Copper-beryllium alloy with high strength

A sucker rod guide having low friction and high wear resistance is disclosed herein, along with a fluid extraction system comprising the same. At least a part of the exterior surface of the sucker rod guide is formed from a cold worked and spinodally-hardenable or spinodally-hardened copper alloy comprising from about 5 to about 20 wt % nickel, and from about 5 to about 10 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi. The guide includes a smoothbore adapted to surround and engage the surface of a sucker rod. The exterior surface of the guide can include grooves miming between the two ends. In particular embodiments, the guide is made by joining together two identical guide segments. In other embodiments, the guide is a single integral piece molded around a sucker rod.
