Why are Wheel spacers made from 7075-T6 aluminum better than ones made from 6061-T6 aluminum.

Why are Wheel spacers made from 7075-T6 aluminum better than ones made from 6061-T6 aluminum.

When it comes to wheel spacers, there's a distinct advantage to using 7075-T6 forged aluminum over 6061-T6 aluminum. Let me break it down for you:

  1. Strength and Durability: 7075-T6 forged aluminum is known for its exceptional strength-to-weight ratio. To put it in perspective, the tensile strength of 7075-T6 can be up to 83,000 psi, and its yield strength can be up to 73,000 psi. On the other hand, 6061-T6 has a tensile strength of around 45,000 psi and a yield strength of around 40,000 psi. These figures suggest that 7075-T6 is approximately 84% stronger in terms of tensile strength and about 83% stronger in terms of yield strength than 6061-T6. This makes it significantly better suited to handle the stresses and loads that wheel spacers endure. This extra strength ensures that the spacers can withstand the forces exerted by the wheels and the vehicle's weight, providing a robust and durable solution.

  2. Weight Reduction: Despite its increased strength, 7075-T6 forged aluminum is also lighter than 6061-T6 aluminum. This weight reduction is crucial, especially when it comes to unsprung weight. By utilizing lighter materials, such as 7075-T6 aluminum, in the wheel spacers, you can help minimize the impact on suspension performance, handling, and overall vehicle dynamics.

  3. Resistance to Fatigue: 7075-T6 forged aluminum exhibits superior resistance to fatigue compared to 6061-T6 aluminum. Fatigue occurs when a material weakens over time due to repeated stress cycles. With its enhanced fatigue resistance, 7075-T6 aluminum ensures that the wheel spacers maintain their structural integrity even after prolonged use, providing a longer lifespan and increased reliability.

  4. Corrosion Resistance: Both 7075-T6 and 6061-T6 aluminum alloys offer good corrosion resistance, but 7075-T6 aluminum takes it up a notch. This makes it particularly advantageous for wheel spacers that are exposed to various environmental conditions, such as rain, snow, salt, and road debris. The improved corrosion resistance helps to maintain the spacers' appearance and structural integrity over time.

It's important to note that the decision between 7075-T6 and 6061-T6 spacers depends on your specific needs, driving style, and budget. It's worth mentioning that 7075-T6 forged aluminum can be more expensive than 6061-T6 aluminum due to the increased manufacturing complexity and material properties. However, the benefits in terms of strength, weight reduction, fatigue resistance, and corrosion resistance make it a preferred choice for applications like wheel spacers, where performance and reliability are paramount.

So, if you're looking for wheel spacers that can handle the rigors of the road, provide a weight advantage, resist fatigue, and stand up to corrosion, 7075-T6 forged aluminum is the way to go. It's a top-notch material that will help ensure your wheel spacers are not only functional but also built to last. That is why ROKBLOKZ Elite Wheel spacers will hold up better and out perform most other options available on the market.
