Hex Socket Head titanium Bolt DIN912
DIN912 titanium bolt material:gr2 gr5 gr7 gr12 Size: m2-m36
Product Introduction
Product Overview
Titanium hex socket head bolts are high-performance fasteners made from pure titanium or titanium alloy materials. Titanium has a low density and extremely high strength, making it one of the most attractive materials for applications requiring lightweight structures with excellent mechanical performance.
The density of titanium is approximately 4.51 g/cm³, which is higher than aluminum but significantly lower than steel, copper, and nickel. However, titanium offers an outstanding strength-to-weight ratio, which is among the highest of commonly used engineering metals.
Titanium bolts also exhibit excellent corrosion resistance, remaining stable in many oxidizing, neutral, and weakly reducing environments. In addition, titanium is non-toxic, non-magnetic, and environmentally friendly, making it suitable for sensitive applications such as medical devices and electronic equipment.
Because of these superior properties, titanium fasteners typically have a higher cost compared with conventional steel fasteners.
