Product Overview

Platinum-Iridium Alloy Ring (Pt90Ir10/Pt80Ir20) - High-Temperature Resistant Sealing & Precision Component engineered for demanding Medical and Aerospace applications.

Key Features & Benefits

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.
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.

Frequently Asked Questions (FAQ)

What are the primary differences between Pt90Ir10 and Pt80Ir20 alloys?

Pt90Ir10 is the standard medical grade offering excellent biocompatibility. Pt80Ir20 contains more iridium, which significantly increases hardness and wear resistance, making it ideal for high-friction mechanical seals.

Can these rings withstand extreme chemical environments?

Yes, Platinum-Iridium alloys are among the most corrosion-resistant materials available. They successfully resist aqua regia, sulfuric acid, and most molten glass or bodily fluids.

What is the maximum operating temperature for these components?

These rings maintain their structural integrity and dimensional stability at temperatures ranging from cryogenic levels (-270°C) up to 1200°C (2192°F).

Are custom sizes and tolerances available?

Absolutely. We offer precision machining with tolerances as tight as ±0.005mm. Outer diameters can range from 5mm to 200mm based on your specific application requirements.

How are the products protected during shipping?

To prevent contamination or oxidation of surface finishes, all rings are sealed in Argon-purged containers or specialized protective packaging to ensure they arrive in pristine condition.
