COPPER ALLOY FORGINGS
In forging copper alloys there is a 2:1 grain reduction which is a reduction ratio that means the cross-sectional area of the starting stock is reduced by half during the forging process, helping to break down coarse cast structures and improve mechanical integrity. Plastic deformation at elevated temperatures closes internal micro-cavities, eliminates porosity, and initiates dynamic recrystallization. Grain alignment during forging makes parts tougher than castings.

RWMA (Resistance Welding Manufacturing Alliance) Copper Alloys are standardized material groups categorized by mechanical hardness and electrical conductivity for use in resistance welding. Large diameter solid rounds, blocks and rolled rings are available in:
RWMA Class 2 C18200 chromium-copper and chromium-zirconium copper C18150. These heat-treatable alloys balance high thermal/electrical conductivity with superior hardness and wear resistance, making them the standard choice for welding cold/hot-rolled steels and coated materials.
RWMA Class 3 C18000 Copper-nickel-silicon-chromium and copper-nickel-beryllium C17510 prioritize high mechanical strength and wear resistance over conductivity, serving well for projection welding dies, flash/butt welding electrodes, and heavy-duty structural parts.
RWMA Class 4 C17200 beryllium-copper alloy with extreme hardness and compressive strength. This alloy is utilized for specialized high-pressure tooling facings, seam welder bushings, and flash/butt welding dies .
