Titanium Spring Washers DIN127

 

Titanium Spring Washers DIN127, also known as titanium spring washers or titanium open-ended spring washers, are ring-shaped elastic fasteners with a beveled cut that generate sustained axial tension through elastic deformation, effectively preventing bolts from loosening under vibration, impact, or temperature cycling conditions. Precision-manufactured from aerospace-grade titanium alloy (GR2 / GR5 Ti-6Al-4V), they combine four core advantages-**ultra-lightweight, high corrosion resistance, high specific strength, and non-magnetic properties**-making them an ideal upgrade and replacement for steel and stainless steel spring washers.

 

 

GR2 (Industrial-Grade Pure Titanium)

- Tensile strength ≥345 MPa, yield strength ≥275 MPa

- Good formability and excellent corrosion resistance

- Suitable for: general corrosive environments, lightweight applications, and routine marine/chemical service conditions

 

GR5 (Ti-6Al-4V Titanium Alloy)

- Tensile strength ≥895 MPa, yield strength ≥828 MPa

- High strength, high elasticity, fatigue resistance, and superior heat resistance

- Suitable for: Severe operating conditions involving intense vibration, heavy loads, and high temperatures (aerospace, motorsports, wind power, etc.)

1. Extreme Lightweight Design

Titanium alloy has a density of approximately 4.43–4.51 g/cm³, making it about 40% lighter than ordinary steel gaskets and only about 60% as dense as stainless steel. In weight-sensitive fields such as aerospace, motorsports, and lightweight robotics, this advantage directly reduces structural loads and energy consumption.

2. Absolute Corrosion Resistance

Unlike galvanized steel washers or even stainless steel washers, titanium is completely inert to seawater, chloride ions, industrial chemicals, and acids; it will not rust or degrade. In harsh corrosive environments such as marine engineering, desalination, and chemical piping, titanium alloy spring washers can maintain joint integrity over the long term.

3. High Strength and Excellent Elasticity

GR5 (Ti-6Al-4V) titanium alloy has a tensile strength of over 895 MPa and a yield strength of ≥828 MPa, providing spring force and hardness comparable to high-strength steel lock washers, yet weighing only about 45% as much. Pure titanium GR2 spring washers retain more than 85% of their initial spring force even after repeated compression.

4. Non-magnetic

Titanium is a non-ferromagnetic material that does not interfere with the normal operation of precision electronic instruments, semiconductor manufacturing equipment, medical devices (such as MRI machines), or high-energy physics equipment.

5. Stability Across a Wide Temperature Range

GR2 spring washers are suitable for temperatures ranging from -252°C to 315°C, while GR5 spring washers can withstand temperatures from -252°C to 538°C, maintaining stable elasticity in both extremely high and low-temperature environments.

6. Aesthetic Surface Treatment Options

Titanium alloys naturally possess excellent surface coloring capabilities. Through anodizing, they can be finished in a variety of colors, including gold, blue, and purple, combining functionality with visual appeal. They are suitable for applications such as high-end consumer electronics and custom bicycle/motorcycle modifications.
