Why Bullite Uses 5454-H Aluminum

Why Bullite Uses 5454-H Aluminum

At the very core, comes to metal component that dictates the strength, the flexibility, and the break-ability of the wheel. Aluminum alloy and steel are two common materials that make up the wheel, and the controversy between which one is better continues to be debated. Let's look at to two together.


Steel wheels are made of iron and carbon. With a simple manufacturing process, a low cost and price, and a strong resistance to metal fatigue, steel shows it in many rims throughout the industry. They have increased durability, which allows for easier repair and refinish. These wheels/rims have increased resistance to impact cracks, damage to deicers, gravel and brake dust, making them more popular for winter driving. These qualities allow for more four-season commuting as well as recreational off-roading and/or traveling in heavy snow.

However, they are much heavier than aluminum alloy wheels. This can cause a lot of issues with the wheels themselves.

1. Large inertia of steel wheels, or in layman's terms, requires more force to turn the wheels, and therefore more energy. 

2. Braking also requires more energy, and its braking qualities are inferior to aluminum alloy wheels because of that weight.

3. The poor thermal conductivity of steel causes it to have poor heat dissipation, making it unable to withstand the thermal decay of tires and the braking system.


Aluminum alloy wheels can be made up of metal elements such as manganese, magnesium, chromium, titanium, etc. Aluminum alloy wheels are much lighter in weight and therefore, less inertial resistance. This provides a significant reduction of fuel requirements, compared to steel. The thermal conductivity of 5454 aluminum plates are about three times that of steel. The heat dissipation is much better, allowing it to withstand the thermal decay of tires and braking system. 

The deformation of aluminum wheel is small, making it easier for cars equipped with aluminum wheels to drive straight, thus decreasing the resistance caused by tire rolling. This is quite beneficial for driving over rocks and other uneven terrain.

For our 5454 Aluminum plates, it is made up of the following, which allows its different chemical properties to strengthen our wheels:

Aluminium: 94.5 to 97.1%
Chromium: 0.05 to 0.20%
Copper: 0.1% max
Iron: 0.4% max
Magnesium: 2.4 to 3.0%
Manganese: 0.5 to 1.0%
Silicon: 0.25% max
Titanium: 0.2% max
Zinc: 0.25% max
Residuals: 0.15% max

In conclusion, with its rich tempers, energy-saving qualities, light weight and superior appearance, the 5454-H Aluminum plate brings you a better driving experience from the moment of purchasing to your first driving experience.
