Product Description

C18000 CuCrNi2Si Copper Chromium Nickel Silicon Alloys

Description

C18000 is a Copper Chromium Nickel Silicon Alloy. This alloy meets the mechanical requirements of RWMA Class III Beryllium Copper without the using Beryllium. C180 Copper has very good mechanical strength along with moderate electrical and thermal conductivity.
C18000 Copper Chromium Nickel Silicon Alloy is typically used in resistance welding tips, resistance welding wheels and fixtures, stud welding collets and tips, inserts in plastic injection molds, blow mold pinch offs, mold cavities for blow molds, hot runner systems for injection molds, cores, and ejector pins for injection molds, plunger tips for metal die casting machines and casting dies.
(Other Name: CuCrNi2Si, RWMA Class 3, DIN 2.0855, CW111C to EN, CDA180.)
