C7026 Type CuNi2Si Copper Alloy Strips
Description
C7026 Copper Nickel Silicon is the copper base alloy which is heat treatable, high in strength and conductivity. The properties of this alloy can fairly be obtained after its heat treatment. The alloy is rich on properties like high hardness, strength and wear resistance with relatively high electrical and thermal conductivity.
(Other Name: CuNi2Si; C7026; QSi0.6-2.)
