C17200 beryllium copper

Introduction of C17200 beryllium copper

C17200 beryllium copper is a copper-beryllium alloy that contains 2% beryllium by weight. Some key points about C17200 beryllium copper:

Composition: Copper 98%, Beryllium 2%
Other name: Alloy 25, CuBe2
China: QBe2, QBe1.9
America (US): C17200
Germany: QBe2, QBe1.7
Japan: C1720
Russia: BPB2, BPBHT1.9

C17200 beryllium copper is produced by Melting of Beryllium Copper Master Alloy ingot and  high-purity copper ingot.  The addition of beryllium to copper produces an alloy exhibiting greater strength, stiffness and wear resistance compared to ordinary copper. C17200 alloy also displays enhanced conductivity, dimensional stability and spring properties essential for various applications.
