Working with C95400 Cont Cast
Is C95400 easy to machine?
Machines at about 60 % of free-cutting brass: tough, gummy chips need sharp positive-rake carbide, rigid setup, moderate speed and generous coolant; HT material is harder and abrasive on tooling.
Can C95400 be welded?
GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well with 150–250 °C preheat and clean oxide removal; avoid oxyfuel and soldering because of the tenacious alumina film.
Can C95400 be formed, bent or molded?
Casting alloy — sand, centrifugal and continuous cast; use bottom gating and good filtering to keep alumina dross out, feed heavily due to high solidification shrinkage; not cold formable.
What surface finishes work on C95400?
Takes a good mechanical polish and develops a stable olive-brown patina; not anodizable — use passivation, lacquer or paint for appearance, and electroless nickel/chrome where extra wear resistance is needed.

C95400 Cont Cast — frequently asked
What is C95400 Cont Cast used for?
C95400 Cont Cast is typically used for aluminum bronze gears and worm wheels, heavy-duty bushings and bearing sleeves, valve seats and valve components, wear plates and gib strips, forming die and press inserts and pump casings and impellers. In short: shock-load bearing bronze.
What is the yield strength of C95400 Cont Cast?
C95400 Cont Cast has a typical yield strength of 262 MPa (38 ksi) and a tensile strength of 620 MPa (89.9 ksi) — stronger than 55% of copper alloy grades. Strength varies by condition: see the 3 listed tempers.
Is C95400 Cont Cast easy to machine?
Reasonably — machinability is rated fair (50/100, better than 69% of copper alloy grades). Machines at about 60 % of free-cutting brass: tough, gummy chips need sharp positive-rake carbide, rigid setup, moderate speed and generous coolant; HT material is harder and abrasive on tooling.
Can C95400 Cont Cast be welded?
Yes — weldability is rated good (60/100). GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well with 150–250 °C preheat and clean oxide removal; avoid oxyfuel and soldering because of the tenacious alumina film.

Can C95400 Cont Cast be formed, bent or molded?
Casting alloy — sand, centrifugal and continuous cast; use bottom gating and good filtering to keep alumina dross out, feed heavily due to high solidification shrinkage; not cold formable.
What is the maximum service temperature of C95400 Cont Cast?
C95400 Cont Cast is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C95400 As Cast and C95400-HT?
As Cast is the default condition — default stocked condition for gears, bushings and valve components where 586 MPa UTS and ~170 HB are sufficient. HT: pick when maximum strength, hardness and wear resistance are needed (heavily loaded worm gears, dies, bearing sleeves) and when de-aluminification resistance must be improved. Yield strength is 241 MPa in As Cast versus 372 MPa in HT.
