The titanium and gold alloy, particularly the intermetallic compound Ti₃Au, represents a groundbreaking material that fuses the biocompatibility of titanium with the prestige and stability of gold—resulting in one of the hardest, most wear-resistant and medically safe alloys known today.
As a forward-thinking titanium supplier, Ti Time Company specializes in custom alloy development, including Ti-Au alloys for medical, industrial, and luxury applications.

1. Experience: Pioneering Titanium Alloy Solutions
With over 20 years of experience in titanium metallurgy, intermetallic compound production, and custom alloy manufacturing, Ti Time Company supports clients in healthcare, aerospace, electronics, and high-end consumer markets.
Our development and production capabilities allow us to precisely control alloying ratios, crystalline structure, and post-processing to deliver Ti-Au alloys with superior mechanical and biological properties.
2. What Is Ti₃Au (Titanium and Gold Alloy)?
Ti₃Au is a crystalline intermetallic alloy with a chemical ratio of three parts titanium to one part gold. Unlike traditional mixed-metal alloys, Ti₃Au features a unique cubic structure that significantly enhances its physical properties.
✦ Hardness and Strength
Vickers Hardness: ~800 HV
4x harder than pure titanium
Outperforms stainless steel and traditional gold alloys (300 HV or less)
✦ Wear Resistance
Wears 70% less than standard titanium
Suitable for high-friction, load-bearing applications
✦ Biocompatibility
Combines gold’s inertness and titanium’s osseointegration capabilities
Surpasses traditional medical-grade titanium in implant performance
✦ Corrosion Resistance
Inherits titanium’s passivating oxide layer
Maintains long-term stability in physiological and harsh environments
✦ Magnetic and Mechanical Properties
Stronger yield and tensile strength than its base metals
Mild magnetic behavior useful in specialized electronics
3. Applications of Titanium-Gold Alloy

✅ Scalable production from grams to kilograms for R&D or full-scale manufacturing
FAQs – Titanium and Gold Alloy
What makes Ti₃Au better than pure titanium for implants?
Ti₃Au offers significantly higher hardness and wear resistance, making it ideal for long-term load-bearing implants like hips, knees, or dental posts.
Is Ti₃Au safe for the human body?
Yes. Both gold and titanium are biocompatible, and the alloy has been shown to support osseointegration and biological stability without adverse reactions.
Can Ti Time Company produce custom Ti-Au ratios?
Absolutely. We offer custom formulations and processing options based on client-specific performance or aesthetic requirements.
Is Ti₃Au suitable for jewelry or luxury goods?
Yes. It offers a unique gold-tone appearance combined with superior hardness, making it ideal for scratch-resistant watch cases and rings.
How does Ti₃Au compare to stainless steel in durability?
Ti₃Au has 4x the hardness of stainless steel and much better biological and corrosion resistance, especially in implant or high-end consumer use cases.
