Product Description

Platinum-Iridium Alloy Ring (Pt90Ir10/Pt80Ir20) - High-Temp Resistant Sealing & Precision Component for Medical/Aerospace

Key Features

Features	Benefits
Premium Pt-Ir Alloy	90% Platinum + 10% Iridium (or Pt80Ir20) for unbeatable corrosion resistance (resists acids, alkalis, and high temperatures up to 1200°C).
Ultra-Low Thermal Expansion	Coefficient of thermal expansion (CTE) ≈ 9×10/°C - maintains dimensional stability in extreme temperature fluctuations.
High Hardness & Wear Resistance	HV 300-400 hardness (6x harder than pure platinum) - ideal for high-friction sealing applications (e.g., valve seats, gaskets).
Biocompatibility	ISO 10993/USP Class VI certified - safe for medical implants, no allergic reactions or tissue irritation.
Precision Machining	Tolerance as tight as ±0.005mm (5μm) - suitable for optical, semiconductor, or metrology instruments requiring micron-level accuracy.

Technical Specifications

Parameter	Value Range
Alloy Composition	Pt90Ir10 (standard), Pt80Ir20 (high-wear), or custom ratios (e.g., Pt70Ir30)

Surface Finish	Mirror-polished (Ra ≤ 0.02μm), Electropolished, or Ground (for sealing surfaces)
Operating Temperature	-270°C to 1200°C (-454°F to 2192°F)
Chemical Resistance	Resists aqua regia, sulfuric acid, molten glass, and bodily fluids
Mechanical Properties	Tensile Strength: 800-1000 MPa; Elongation: 15-20%; Density: 21.5 g/cm³

Applications

• Medical & Dental: Implantable rings (e.g., cochlear implants, dental abutments), surgical tool pivot points, and drug delivery device components.
• Aerospace & Defense: Jet engine turbine seals, satellite thruster gaskets, and missile guidance system precision rings.
• Semiconductor & Optics: Wafer processing chamber seals (resists plasma etching), laser mirror mounts, and optical fiber alignment rings.
• Metrology & Standards: Calibration weights, length standards (e.g., gauge blocks), and high-precision bearing races.
• Extreme Environments: Nuclear reactor control rod seals, deep-sea submersible O-rings, and high-pressure chemical reactor gaskets.
