Beryllium copper alloys can be strengthened through cold work or by a solid solution addition that will enhance strain hardening. like 521 alloy. Copper is widely known as a soft and malleable metal. A copper alloy, on the other hand, offers users a wide variety of useful combinations of mechanical properties. Copper alloys offer users adaptability that is not available with all .
· C17200 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW101C is the EN numeric designation for this material. C17200 is the UNS number. Additionally, the EN chemical designation is CuBe2. Older literature may refer to this material as ASTM Alloy 25, but this is now discouraged.
