What is C95410?
C95410 is a nickel-modified aluminum bronze casting alloy, essentially C95400 with added nickel so that it responds to quench-and-temper (TQ50) heat treatment. In the heat-treated condition it gives 241 MPa yield, 586 MPa tensile, 13% elongation and 170 HB (88 HRB) with a 110 GPa modulus and density of 7.45 g/cm³, which suits heavy bushings, gears and wear plates poured as sand, centrifugal or continuous castings. Limits are 300 °C maximum service, 13% IACS conductivity, a machinability rating of 55 and no formability (rating 20); C95400 is the lower-cost choice when heat treatment is not needed. C95410 has a density of 7.45 g/cm³ (0.269 lb/in³), lighter than 99% of copper alloy grades. It melts at 1,038°C (1,900 °F). C95410 has a yield strength of 241 MPa (35 ksi) and a tensile strength of 586 MPa (85 ksi) — stronger than 53% of copper alloy grades. Elongation at break is 13% and the elastic modulus is 110 GPa (16 Msi).

Working with C95410
Is C95410 easy to machine?
Machines like a tough gummy bronze at ~60 % of AISI 1212 — use sharp positive-rake carbide, rigid setups, moderate speed with heavy feed and flood coolant; heat-treated stock is harder and abrasive due to kappa phases.
Can C95410 be welded?
GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2/A3) works well; preheat 150–200 °C on heavy sections, remove alumina film with stainless brush, and re-heat-treat if TQ50 properties are required across the joint.
Can C95410 be formed, bent or molded?
Supplied as sand, centrifugal or continuous castings — feed generously with chills and bottom-gating to avoid alumina dross and shrinkage; not a cold-formable product.
C95410 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on C95410?
Takes a bright mechanical polish but oxidises to a golden-brown patina; use passivation/lacquer or elastomer seals for appearance parts, and avoid anodizing (not applicable to copper alloys).
Surface treatments FabDigit runs on copper alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).
How much does C95410 cost?
C95410 is a high-cost copper alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
C95410 — frequently asked
What is C95410 used for?
C95410 is typically used for heavy-duty bushings, gears and wear plates. In short: heat-treatable aluminum bronze; stronger than C95400; weldable wear bronze.
What is the yield strength of C95410?
C95410 has a typical yield strength of 241 MPa (35 ksi) and a tensile strength of 586 MPa (85 ksi) — stronger than 53% of copper alloy grades. Strength varies by condition: see the 2 listed tempers.
Is C95410 easy to machine?
Reasonably — machinability is rated good (55/100, better than 71% of copper alloy grades). Machines like a tough gummy bronze at ~60 % of AISI 1212 — use sharp positive-rake carbide, rigid setups, moderate speed with heavy feed and flood coolant; heat-treated stock is harder and abrasive due to kappa phases.
Can C95410 be welded?
Yes — weldability is rated good (65/100). GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2/A3) works well; preheat 150–200 °C on heavy sections, remove alumina film with stainless brush, and re-heat-treat if TQ50 properties are required across the joint.

Can C95410 be formed, bent or molded?
Supplied as sand, centrifugal or continuous castings — feed generously with chills and bottom-gating to avoid alumina dross and shrinkage; not a cold-formable product.
What is the maximum service temperature of C95410?
C95410 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 C95410-F and C95410-TQ50?
F is the default condition — standard stock condition for bushings, wear plates and general marine castings where 585 MPa class strength is enough. TQ50: choose when maximum strength, hardness and wear life are needed — e.g. heavily loaded worm gears, forming dies and valve trim; ductility drops slightly. Yield strength is 241 MPa in F versus 310 MPa in TQ50.
How much does C95410 cost?
C95410 is a high-cost copper alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
