High-Performance Gold with 30-50% Less Material

Daumet's patented gold-tungsten alloys reduce gold consumption by 30-50% while enhancing hardness, wear resistance, and thermal stability.
From optics to aerospace, we partner with R&D teams exploring gold applications in extreme environments where cost and performance are equally critical.

COST OPTIMIZATION

Reduce gold consumption by 30-50% while maintaining chemical and mechanical performance.
Our gold-tungsten coatings enable thinner deposits (1-5µm vs 10-20µm traditional) with superior adhesion and durability—protecting R&D budgets against gold price volatility.

ENHANCED MATERIAL PROPERTIES

Gold-tungsten alloys deliver mechanical performance unattainable with pure gold: 5-50× harder than 24K, wear resistance comparable to hardened steel, and thermal stability beyond 1500°C—while maintaining >80% electrical conductivity. These properties enable gold use in high-stress applications where pure gold would fail.
