Patent number: 11725463Abstract: A cold worked and spinodally-hardened copper alloy comprising from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper, and having a 0.2% offset yield strength of at least 75 ksi, is used to form a sucker rod coupling or subcoupling. Each coupling is formed from a core having two ends, each end having an internal thread. These box ends engage the pin of a sucker rod or other rod. The exterior surface of the core includes grooves running between the two ends.Type: GrantFiled: April 15, 2021Date of Patent: August 15, 2023Assignee: Materion CorporationInventors: William D.

Patent number: 11643713Abstract: A spinodal copper-nickel-tin alloy with a combination of improved impact strength, yield strength, and ductility is disclosed. The alloy is formed by process treatment steps including solution annealing, cold working and spinodal hardening. These include such processes as a first heat treatment/homogenization step followed by hot working, solution annealing, cold working, and a second heat treatment/spinodally hardening step. The spinodal alloys so produced are useful for applications demanding enhanced strength and ductility such as for pipes and tubes used in the oil and gas industry.Type: GrantFiled: October 20, 2020Date of Patent: May 9, 2023Assignee: Materion CorporationInventors: W.

Patent number: 11352838Abstract: A sucker rod string is formed from sucker rods and sucker rod couplings. The sucker rod couplings are formed from a spinodally-hardened copper alloy comprising from about 8 to about 20 wt % nickel, and from about 5 to about 11 wt % tin, the remaining balance being copper, and having a sliding coefficient of friction of 0.4 or less when measured against carbon steel. The sucker rod string has low friction and improved pumping stroke, enhanced pumping capacity, and less load in the overall system.Type: GrantFiled: October 7, 2020Date of Patent: June 7, 2022Assignee: Materion CorporationInventors: Fritz C.

Patent number: 11326242Abstract: Disclosed are various processes for preparing a strip or plate of a copper-nickel-tin alloy. The processes begin with an input, usually of a rectangular shape. The input is hot rolled and annealed. The input is then subjected to a first cold reduction, a first annealing a second cold reduction, a second annealing, a third cold reduction, and a third annealing. If desired, a fourth cold reduction, a fourth annealing, and a fifth cold reduction may be performed. The resulting strip or plate is very smooth and has increased fatigue life, along with high strength.Type: GrantFiled: February 2, 2018Date of Patent: May 10, 2022Assignee: Materion CorporationInventors: Karl R. Ziegler, John E. Gatehouse, Bruce D. Schmeck, Fritz C. Grensing

Patent number: 11174688Abstract: 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.Type: GrantFiled: December 28, 2018Date of Patent: November 16, 2021Assignee: Materion CorporationInventors: Fritz C.
