Abstract: 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.

Abstract: 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 106 cycles of testing.

Abstract: Methods for producing a coiled strip of metal matrix composite (MMC) material are disclosed. The methods include a combination of hot rolling and warm rolling processes that reduce the thickness of the input material and increase its ductility. The resulting MMC strip can be coiled, which is useful for high volume coil-to-coil applications.

Abstract: Systems and methods for reducing the thickness of a strip of an aluminum-based material are disclosed. The aluminum-based material is pre-heated before running the material through a warm rolling process. The systems include devices for pre-heating, which can include a heated payoff station or a dedicated pre-heating station that applies heated rolls or acts as a heated tunnel.
