We carry a wide variety of platinum 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 platinum 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.

Platinum iridium wire is a high-performance alloy wire made by combining platinum (Pt) and iridium (Ir). It retains platinum’s excellent corrosion resistance and electrical conductivity while gaining enhanced mechanical strength, wear resistance, and high-temperature stability from iridium. Common alloys include PtIr10 (90% Pt, 10% Ir) and PtIr20 (80% Pt, 20% Ir).

Platinum iridium wire offers higher wear resistance and mechanical strength while maintaining excellent corrosion resistance.
