Cupro NSS® CuNi2Si Cr Hard Copper Alloy
Cupro NSS® CuNi2Si Cr
RWMA Class3 - C18000 - 2.0855
CuproNSS® is a copper alloy developed by Sağlam Metal.
Suitable for applications requiring high mechanical properties along with good electrical and thermal conductivity.
Hard copper alloy with rigidity, very good abrasive resistance and toughness.
Very good thermal conductivity despite not containing Beryllium.
Same hardness as Cupro CB, but with very high electrical conductivity.
Ideal for use in piston heads in injection moulding and in cooling blocks.
