Use of Grade 2 Titanium Rolls in Sporting Equipment

Introduction

Titanium is known for its high strength‐to‐weight ratio and corrosion resistance. It is used in several industries including aerospace, medical engineering and the manufacture of sporting equipment. This case study examines the application of Grade 2 titanium rolls in the development of sporting equipment.

Understanding Grade 2 Titanium Rolls

Grade 2 titanium, also referred to as commercially pure titanium, is identified by TM3367. Owing to its corrosion resistance, formability and weldability, it is one of the most frequently used titanium grades. Grade 2 titanium primarily consists of nearly pure titanium with trace amounts of oxygen and iron, which impart defined mechanical properties.

Applications of Grade 2 Titanium Rolls in Sporting Equipment

In sporting equipment, Grade 2 titanium is used as follows:

1. Fastening Elements and Components: Grade 2 titanium is used for joining elements such as bolts and screws. Its corrosion resistance is beneficial for equipment that is used outdoors or under wet conditions.

2. Small Components: It is applicable for small parts such as hinges, brackets or clips where corrosion resistance and low weight are required.

3. Rackets and Tennis Racquets: On certain occasions, titanium alloys (not necessarily Grade 2) are used in the construction of golf club heads, tennis racquets or similar items to achieve a measurable balance of strength, durability and weight reduction.

4. Protective Equipment: Titanium or its alloys may be incorporated in protective equipment such as helmets and face masks in specific sports. These materials provide sufficient strength and impact resistance while maintaining low weight.

5. Accessories: Titanium is also used for accessories that accompany sporting equipment, including bracelets, key chains and designated toolkits for equipment maintenance.

6. Custom Applications: Certain manufacturers of customised sporting equipment use Grade 2 titanium for specific applications where its mechanical properties are required. It is important to note that although Grade 2 titanium offers good corrosion resistance and low weight, its strength is lower than that of other titanium grades such as Grade 5 (Ti‑6Al‑4V). Consequently, its use in sporting equipment is generally limited to non‐structural components or particular applications where these properties are advantageous.

Consult a materials engineer or designer to determine the most appropriate material for a given sporting equipment application, taking into account factors such as strength, weight and corrosion resistance.

Conclusion

In summary, Grade 2 titanium continues to be employed in the manufacture of sporting equipment including fastening elements, small components, and racquets. In the case of customised applications, high-end manufacturers make use of Grade 2 titanium to meet specific performance criteria. As sporting equipment designs evolve, Grade 2 titanium remains a viable option and contributes to ongoing development in the sports industry.
