Gold & Gold Alloys

High-Purity Gold & Specialty Gold Alloys for High-Reliability Electrical Applications

When electrical performance must remain consistent over years of service, engineers often specify gold. Its exceptional resistance to oxidation, low contact resistance, excellent conductivity, and superior bondability make it one of the most reliable materials for electrical interconnections, bonding wire, connectors, and precision electronic components.

Gold is especially valuable in low-voltage and low-current applications where even microscopic oxidation can compromise signal integrity. Its stable electrical properties and outstanding corrosion resistance ensure long-term reliability in mission-critical environments.

For more than 125 years, Sigmund Cohn Corp. has manufactured precision gold products and specialty gold alloys for OEM manufacturers serving the medical,

aerospace, electronics, sensing, and industrial markets. Our gold products are available in precision wire, ultra-fine wire, ribbon, strip, tubing, rod, and custom-fabricated components manufactured to exacting dimensional and metallurgical specifications.
