What is C95410-TQ50?
C95410-TQ50 is C95410 supplied in the TQ50 condition — choose when maximum strength, hardness and wear life are needed — e.g. heavily loaded worm gears, forming dies and valve trim; ductility drops slightly. C95410-TQ50 has a yield strength of 310 MPa (45 ksi) and a tensile strength of 689 MPa (99.9 ksi) — stronger than 64% of copper alloy grades. Elongation at break is 8% and the elastic modulus is 110 GPa (16 Msi). C95410-TQ50 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).

Working with C95410-TQ50
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.
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).

C95410-TQ50 — frequently asked
What is C95410-TQ50 used for?
C95410-TQ50 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-TQ50?
C95410-TQ50 has a typical yield strength of 310 MPa (45 ksi) and a tensile strength of 689 MPa (99.9 ksi) — stronger than 64% of copper alloy grades. Strength varies by condition: see the 2 listed tempers.
Is C95410-TQ50 easy to machine?
Reasonably — machinability is rated fair (48/100, better than 68% 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-TQ50 be welded?
Yes — weldability is rated good (60/100). 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.
What surface finishes work on C95410-TQ50?
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).
Can C95410-TQ50 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-TQ50?
C95410-TQ50 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.
