C96900 Nickel Tin Bronze is a high-performance copper alloy known for its excellent electrical conductivity, corrosion resistance, and strength. This alloy is valued for its non-magnetic properties, making it ideal for applications such as electrical contacts, connectors, and marine fittings. Its composition, which includes nickel and tin along with copper, provides a balance of ductility and hardness, allowing for precision machining and casting.
Volume: 0
When jet engine bearings seize at 30.000 RPM and submarine gears shudder under torpedo-load forces, C96900 Nickel Tin Bronze answers. This copper-tin-nickel alloy (84% Cu, 10% Sn, 6% Ni) laughs at 800°F temps while gliding smoother than graphite. AMS 4880-certified and ITAR-compliant – it’s the silent guardian in F-35 landing gear, nuclear reactor control rods, and oil rigs where failure isn’t an option.

5 REASONS IT OUTLIVES THE MACHINE
Fatigue Slayer
"Endures 100M+ cycles in helicopter swashplates – 5X lifespan of aluminum bronze."
Heat Immunity
"Maintains hardness at 800°F – critical for afterburner bearings in fighter jets."
Galling Resistance
"Zero cold-welding in missile launch rails even at 90.000 psi contact pressure."
Non-Magnetic
"Magnetic permeability <1.01 μ – essential for submarine sonar arrays."
Spark-Free
"MSHA/NEC Class I Div 1 certified for explosive methane mines."
KEY FEATURES: ENGINEERED SECRETS
Corrosion Armor: Survives 5.000-hr salt spray tests (ASTM B117) without pitting
Thermal Conductivity: 46 W/m·K – dissipates heat 3X faster than stainless steel
Embeddability: Traces silica dust in desert turbine ops, preventing shaft scoring
Dimensional Stability: Holds ±0.0005" tolerance from -65°F to 800°F
PRECISION PROCESSING: MISSION-READY METAL
1 Vacuum Induction Melting (VIM)
"Cu-Sn-Ni alloyed at 10⁻⁴ torr – near-zero gas porosity for flight-critical parts."
2 Electro-Slag Remelting (ESR)
"Ultra-clean ingots with sulfur <0.002% – eliminates sulfide inclusions."
3 Isothermal Forging
"Forged at 1500°F under 40 ksi pressure – directional grain flow for fatigue resistance."
4 Precision Grinding
"Jig-ground to Ra 4μin (0.1μm) – mirror finish for hydraulic servo valves."
