Working with C96600-TB00
Is C96600 easy to machine?
Tough and gummy in the solution-treated state and abrasive when aged — use sharp carbide tooling, low speed with heavy positive feed, rigid setups, flood coolant, and wet-grind only to control beryllium-bearing dust.
Can C96600 be welded?
GTAW/GMAW with matching or Cu-Ni filler is possible but requires low heat input, clean joints, forced local exhaust for beryllium fume, and re-solution + re-ageing to restore strength in the HAZ.
Can C96600 be formed, bent or molded?
Supplied as sand, investment or continuous castings only; design generous fillets and feeders because solidification range is wide, then rough-machine before ageing to limit distortion.
What surface finishes work on C96600?
Takes a high mirror polish suitable for plastic-mould surfaces; can be electroless nickel or hard chrome plated, but do not anodise — passivate or use protective coatings in aggressive service.

C96600-TB00 — frequently asked
What is C96600-TB00 used for?
C96600-TB00 is typically used for plastic injection mold inserts, high-strength bushings, wear-resistant bearings and electrical contact components. In short: age-hardening cast Cu-Ni; high strength with conductivity; mold-insert grade.
What is the yield strength of C96600-TB00?
C96600-TB00 has a typical yield strength of 240 MPa (34.8 ksi) and a tensile strength of 505 MPa (73.2 ksi) — stronger than 52% of copper alloy grades. Strength varies by condition: see the 3 listed tempers.
Is C96600-TB00 easy to machine?
Not especially — machinability is rated poor (28/100, worse than 78% of copper alloy grades). Tough and gummy in the solution-treated state and abrasive when aged — use sharp carbide tooling, low speed with heavy positive feed, rigid setups, flood coolant, and wet-grind only to control beryllium-bearing dust.
Can C96600-TB00 be welded?
With care — weldability is rated fair (35/100). GTAW/GMAW with matching or Cu-Ni filler is possible but requires low heat input, clean joints, forced local exhaust for beryllium fume, and re-solution + re-ageing to restore strength in the HAZ.
What surface finishes work on C96600-TB00?
Takes a high mirror polish suitable for plastic-mould surfaces; can be electroless nickel or hard chrome plated, but do not anodise — passivate or use protective coatings in aggressive service.
Can C96600-TB00 be formed, bent or molded?
Supplied as sand, investment or continuous castings only; design generous fillets and feeders because solidification range is wide, then rough-machine before ageing to limit distortion.
What is the maximum service temperature of C96600-TB00?
C96600-TB00 is rated for continuous use to about 330°C (626 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C96600-TF00 and C96600-TB00?
TF00 is the default condition — standard supply condition: maximum strength, hardness and wear resistance for mould inserts, bearings and high-strength marine parts. TB00: choose when heavy machining or straightening must be done before final ageing; softest and most ductile condition. Yield strength is 585 MPa in TF00 versus 240 MPa in TB00.
