Iridium Pellets Applications

  • High-purity thin film deposition: Used as evaporation source material to create ultra-thin, high-purity iridium coatings for optical and electronic devices.
  • Wear-resistant coatings: Form durable protective layers on precision tools and aerospace components via electron-beam evaporation.
  • Semiconductor industry: Deposit conductive barriers in advanced chip packaging and MEMS devices.
  • X-ray optics: Create reflective coatings for X-ray telescopes and synchrotron radiation equipment.

Iridium Pellets Packaging

Iridium Pellets are carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.

To customize your iridium pellets, please provide the following details:

  1. Size (specify the desired diameter, height, or weight)
  2. Purity (Specify the purity of material required.)
  3. Quantity of the products you need
  4. Alternatively, you can provide a drawing with your specifications.

Once we have these details, we can provide you with a quote within 24 hours.

We carry a wide variety of iridium products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

If you have specific iridium materials that are subject to DFARS, please let us know in advance and we will confirm.

At Heeger Metal, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

Iridium pellets provide ultra-high purity (99.95% or above) and stable evaporation rates, ideal for critical thin-film applications.

Compatible with electron-beam (e-beam) and resistive thermal evaporation systems.

50 nm to 5 μm, controllable via evaporation time/power.
