Aluminium Extrusions in Sports Equipment Sports equipment designers are constantly reviewing the materials they specify and use to ensure the equipment enables the competitor to achieve their best performance in their chosen sport.
The highest professional level, sports are a highly competitive occupation with high prize money depending upon fractions of a second or tenths of a centimetre. However, even the dedicated amateur is willing to invest a great deal of money to improve his or her performance. Thus, just as in other fields, the use of special aluminium alloys in sports can be justified if it leads to enhanced performance.

The sports equipment must exhibit the following qualities:
high quality, safety, durable, light weight, high corrosion resistance, low cost of maintenance

In an industry associated with constant innovation and revamping, the versatility of aluminium extrusions not only improves the efficiency in installing various components, but offers a solution that is both aesthetically pleasing and functional.

Extruded aluminium posts and fittings offer a light weight, durable, corrosion resistant solution that meets those safety requirements.
It is now possible to obtain hurdles made of a lightweight, tubular frame, aluminium construction that are balanced to return to the upright position when knocked over and have a padded top bar for safety.

Racing bike frames and pedals are often made from incredibly strong, light aluminium alloy that can be manipulated into almost any shape and is great for transferring power from the pedals to the wheel. Aluminium has high corrosion resistance and now a good aluminium road bike is a joy to ride.

Why use extruded aluminium instead of other materials?

Aluminium is lighter and thus more portable especially where the same field is used for other sports
Aluminium and its associated fixings are safer by design
Aluminium has a low cost of maintenance compared to other materials
It can be powder coated maintaining its glossy appearance and won’t rust .

Aluminium sports equipment is usually finished with surface treatment such as powder coating or anodising. Goal posts are often powder coated but cycle wheels may well be anodised to increase their surface hardness and thus durability.

Extruded Aluminium Rim for Bicycle

Today, bicycles have become the simplest, most practical and most used means of the vehicle in the world. Sharing Bikes, in particular, is becoming more and more popular. Now the fabric of the bicycle is mainly made of aluminium alloy, magnesium alloy, titanium alloy and carbon fiber. The bicycle frame greatly reduces the weight of the bicycle. The multi-speed transmission mechanism makes the bicycle faster and faster.

While the performance of bicycle has greatly improved, the stability of bicycle operation has been paid more and more attention by consumers, especially the mountain bike. Bicycle wheel or rim is an important part that keeps the bike running smoothly. Because that aluminium alloy is cheaper than the magnesium alloy, titanium alloy, and carbon fiber material, and possesses the advantages of lightweight, not rust, therefore, the most current used is aluminium alloy rim.

Currently, the common aluminium rim contains Single-wall and Double-Wall aluminium rim. Because the spoke & nipple directly touches the inner tire in Single-wall aluminium rim, it’s easy to wear out inner tire. But double-wall aluminium rim is to overcome this shortcoming, at the same time, strengthen the intensity. Therefore double-wall aluminium rim has more advantages.

The material of aluminium bicycle rim is aluminium alloy 6061-T6  alloy 6061 belongs to Al-Mg-Si series, moderate intensity, and has good plasticity and excellent corrosion resistance. In particular, there is no stress corrosion cracking tendency, it has good welding property, corrosion resistance and cold processing. The surface can be anodized oxidation and applied enamel to lacquer. Because alloy 6061 contains a small amount of Cu, the strength and quenching sensitivity is excellent and suitable for complicated environment.
