Description

Platinum-Iridium Alloy is a high-performance, corrosion-resistant material composed of platinum and iridium, typically with iridium content ranging from 5% to 30%. This alloy is valued for its exceptional durability, high melting point, and outstanding chemical inertness, making it a critical material for demanding industrial and scientific applications. It is essential for manufacturers and researchers in sectors requiring extreme reliability and longevity from components exposed to harsh environments.

Application

• Electrode Manufacturing: Primary material for high-stability anodes in electrochemical processes, chlor-alkali industry, and cathodic protection systems.
• Medical Devices & Implants: Used in pacemaker electrodes, neuromodulation devices, and other long-term implantable components due to its biocompatibility and resistance to body fluids.
• Laboratory & Analytical Equipment: Fabrication of crucibles, loops, spatulas, and electrodes for spark emission spectroscopy and other high-temperature analytical techniques.
• Aerospace & Defense: Critical for fuel cell catalysts, jet engine igniter tips, and other components requiring performance under extreme thermal and oxidative stress.
• Jewelry & Luxury Goods: Used in high-end, tarnish-resistant jewelry and luxury watch components, often as a premium alternative to pure platinum for enhanced hardness.
• Glass Manufacturing: Employed in bushings, stirrers, and feeder parts for handling molten glass due to its resistance to thermal shock and corrosion.
• Chemical Processing: Construction of spinnerets for synthetic fiber production and components for handling highly corrosive chemicals at elevated temperatures.

Quality Control

Our Platinum-Iridium Alloy is produced under stringent quality management protocols. Each batch is verified for precise elemental composition, density, and microstructure to ensure consistent performance. We provide full traceability and Certificates of Analysis (COA) detailing purity, alloy ratio, and key physical properties. Our quality systems are designed to meet the exacting standards of the aerospace, medical, and electrochemical industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids, strong oxidizers, and halogens. For long-term storage of fine powders or fabricated components, a controlled inert atmosphere (e.g., argon) is recommended to prevent surface oxidation.
