About Alloy
Titanium 6Al-2Sn-4Zr-2Mo, often referred to simply as Ti-6-2-4-2, is a titanium alloy known for its exceptional strength-to-weight ratio, corrosion resistance, and heat resistance properties. This alloy is part of the alpha-beta titanium alloy family and is primarily used in aerospace and marine applications where high strength and durability are critical. With a composition of 6% aluminum, 2% tin, 4% zirconium, and 2% molybdenum, Ti-6-2-4-2 achieves a balance of mechanical strength and toughness, making it suitable for components subjected to high stress and operating temperatures. Its versatility extends to medical implants, sporting goods, and industrial equipment where lightweight, corrosion-resistant materials are essential for performance and longevity.
