C17500/C17510 offers a combination of high electrical and thermal conductivity with good strength compared to most copper based alloys. C17500 alloy is the mirror image of alloy C17510 in terms of its properties and characteristics. The beryllium copper differ in that C175 specifies a cobalt alloying addition (2.40-2.70%) and alloy 17510 specifies a nickel alloying addition (1.40-2.20%), but their performance are the same.

Alloy 25 c17200 CuBe2 beryllium copper

C17200 CuBe2 beryllium copper

C17200 Cube2 Beryllium Bronze Strip Copper Strip In Coil

C17200 is also known as Alloy 25 and is the most commonly utilized beryllium copper alloy and is notable

for exhibiting  the  highest  strength  and  hardness compared  to commercial  copper alloys.Its strength and

hardness is similar to that of steel. C17200 copper’s ultimate tensile and Rockwell hardness properties in a

peak aged condition are in the 200 ksi range and RC 45 respectively .
