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 powder is used in aerospace coatings, chemical catalysts, medical implants, and high-temperature crucibles due to its extreme corrosion resistance and durability.

We supply 99.9% (3N), 99.95% (3N5), 99.99% (4N) purity, with customized options.

Bulk iridium is inert, but fine powder requires PPE (gloves/masks) to prevent inhalation. MSDS is provided with all shipments.

Heeger Metal, established in 2016 in Colorado, USA, is a specialized supplier and manufacturer of iridium products.
