When sourcing plate for C18000, C18150, and C18200 do you want rolled or forged plate?

Created at : Nov 21, 2022

Copper alloy rolled plates are typically produced by passing cast copper alloy billets between large steel rollers until the required thickness is attained. It is then solution annealed, and precipitation hardened. Cadi Company carries 1/8” to 6” thick plates in C18000 (CuNiSiCr), C18150 (CuCrZr), and C18200 (CuCr).

Copper alloy forged plates are produced by the copper billet being pressed down to the desired thickness. It is then solution annealed, and precipitation hardened. Cadi Company carries 1/8” to 12” thick plates in in C18000 (CuNiSiCr), C18150 (CuCrZr), and C18200 (CuCr).

Which process to choose would depend on the application. Forged plates are less likely to warp or move due to stress when being worked however it is more expensive due to the process. Many customers are pleased with rolled plate results and only use forged when rolled is not available in the desired thickness.

Depending on the size the best option is to purchase the desired size in a rectangle bar that has been extruded at the mill (like making pasta) and has the best cost advantage. Whether we are talking about copper alloys in general or more specifically RWMA copper alloys as well as refractory metals and a wide range of finished consumables in addition to copper alloys for performance, working with a team of professionals can never be understated.  At Cadi we have over 45 years of copper alloy experience and can help answer any questions you make have.
