Overview

99.95% Iridium Rod is an extremely rare and expensive noble metal material with an extremely high melting point (approximately 2446°C) and excellent oxidation and corrosion resistance. It is often used in industrial and scientific research in extreme environments, such as manufacturing thermocouples that can operate at temperatures above 2100°C, crucibles for growing refractory oxide crystals, and high-end optical equipment and vacuum-coated targets. Due to its scarcity and unique physical properties, this high-purity iridium rod is not only indispensable in cutting-edge technology but is also often made into elemental cubes as metal artworks for collections.

As a professional Industrial Iridium Supplier, we can also provide other iridium products such as iridium wire, iridium foil, iridium plate, and iridium target.

Iridium Rod properties

01.

high-temperature performance

Iridium has a very high melting point (about 2446°C) and can withstand high temperatures above 2300°C in air without reacting with melts. It is an ideal material for the manufacture of crystal growth crucibles and high-temperature furnace protective sleeves.

02.

chemical stability

It is practically insoluble in any inorganic acids (including boiling aqua regia) and is not eroded by melts of other metals. This inertness allows it to maintain extremely high structural integrity and stability in extreme chemical environments such as strong acids and alkalis.

03.

mechanical properties

Iridium has a density of up to 22.56 g/cm³ and is hard and wear-resistant. The high density imparts robust mechanical strength, allowing it to excel in aerospace components, spark plugs in high-performance engines, and critical components subjected to high stress.

04.

thermal conductivity

Current and heat transfer are efficient and stable. Its thermocouple products can accurately measure precious metal temperature measurement materials at high temperatures up to 2100°C in the atmosphere, and are widely used in the production of power vacuum devices and electric light source devices.

Application

1. Manufacturing of core components in high-temperature environments

Because Pure Iridium rods have exceptionally high melting points as well as high oxidation resistance, they are suited for long-term, stable performance under extreme thermal conditions. The use of Pure Iridium rods will provide a reduction in downtime caused by failures in components, increased lifetime of equipment component parts, and overall reduction in maintenance costs.

2. Semiconductor and Crystal Growth Equipment

Iridium electrode rods can be used in crucibles and heating elements to grow refractory oxide crystals (such as sapphire and gallium oxide). Because Iridium is both corrosion-resistant and maintains its integrity at high temperatures, it will not contaminate the material from which these crystals are created, thus ensuring that they remain pure and grow efficiently. Additionally, Iridium has excellent thermal conductivity, which allows for more uniform heating, resulting in increased product yield and enabling key technological advances in both semiconductor and optoelectronic.

3. Chemical and hydrogen energy fields

Producing H2 by electrolysis of water, developing catalysts for fuel cells, and making electrodes for use in strong acids or bases through electrolysis. Iridium has high catalytic activity and is chemically inert, which can greatly increase electrolytic efficiency, extend electrode life, and reduce how often a customer has to replace a catalyst. In hydrogen energy, we assist customers in producing green hydrogen at a low cost and with maximum efficiency.

4. Precision Temperature Measurement and Sensing Technologies

Iridium/Iridium-Rhodium thermocouples (specifically for measuring temperatures greater than 2100°C), vacuum coating targets, high-performance optical coatings, etc., provide reliable and stable high-temperature measurement data to guarantee accurate process control in industrial applications. In optics, coating materials provide higher durability and optical performance of lenses and mirrors, which meet the requirements of demanding high-end applications (e.g., aerospace and medical imaging).

5. High-end equipment and wear-resistant parts

99.95% pure iridium bars are used for making superior components in high-pressure/high-friction areas, reducing wear and tear caused by extreme conditions, including oil field and deep ocean drilling, therefore extending the life of equipment.

Shipping Case

99.95% Iridium Rod, Pure Iridium Rods To Thailand

We shipped a high purity iridium rod to Thailand through the cooperation agreement with our customer. The high-end manufacturer in Thailand was able to find an iridium supplier after many merchants failed to meet their quality standards for a metal supplier. Our customer selected us as the successful manufacturing supplier because we were the only business that could consistently produce iridium at the purity standards required by our customer, coupled with our technical capability, as well as providing efficient and professional service; this was based on multiple rounds of communication with our cooperative customer. Once the inquiry, sample testing, and communications were completed, both parties signed a long-term agreement for the sale and shipment of these rods. This shipment demonstrates our strength and reputation in the global marketplace for precious metals, and that we are expanding our international footprint to provide inquiries and invitations for cooperation to suppliers in all countries.

FAQ

Q: What is the standard purity of your iridium rods?

A: Common commercial grade purity is 99.9% or 99.95%; High-purity iridium rods can typically reach 99.99% (i.e., 4N grade). In addition, ultra-high purity iridium matrix with a purity of up to 99.999% (5N grade) can be prepared through special purification processes (such as extraction, ion exchange, reduction, etc.) to meet the requirements of precision fields such as spectroscopic analysis.

Q: Can you provide custom dimensions for iridium electrodes?

A: We can provide. However, whether it can be produced needs to be discussed with the technical team according to the specification range provided by the customer.

Q: How do you ensure the quality of noble metal products?

A: Precision purification process: Through complex chemical extraction, reduction, and ion exchange processes, base metals and other precious metal impurities are effectively removed, ensuring material purity from the source.
Professional instrument testing: Use advanced non-destructive testing equipment, such as a wavelength-dispersive X-ray fluorescence spectrometer (XRF), an inductively coupled plasma (ICP) emission spectrometer, etc., to accurately analyze the composition, impurity content, and surface state of the product.
Authoritative organization certification: A third-party national quality inspection center with CNAS, CMA, and other qualifications will supervise and conduct spot checks or entrusted inspections to ensure that the products comply with national standards or industry norms.

Q: Can Iridium Rods be welded to other metals?

A: Iridium is difficult to weld due to its brittleness, but it can be joined via electron beam welding or brazing in specific vacuum conditions.

Q: What is the typical lead time for custom-diameter Iridium rods?

A: Custom dimensions usually take 2-4 weeks, depending on the order volume. We can deliver within a week if it's in stock.

Q: Do you provide a Certificate of Analysis (COA) with each shipment?

A: Yes, every batch is strictly tested and accompanied by a detailed material test report. And all our bars comply with the international standard of ASTM B684 and the quality inspection standard of ISO 9001.
