Both 7075 and 6061 aluminum alloys are commonly used for yoyo material, and which one is better depends on the specific requirements and preferences of the yoyo player.
7075 aluminum alloy is generally considered to be stronger and more durable than 6061. It has a higher tensile strength and yield strength, and is more resistant to fatigue and wear. As a result, yoyos made from 7075 tend to be more stable, long-lasting, and able to handle more abuse than those made from 6061.
On the other hand, 6061 aluminum alloy is more easily machinable, which means it can be manufactured at a lower cost than 7075. It is also lighter than 7075, which can make yoyos made from 6061 feel more nimble and agile.
Ultimately, the choice between 7075 and 6061 comes down to personal preference and the specific needs of the yoyo player. Some players may prefer the added durability and stability of 7075, while others may prioritize the lighter weight and lower cost of 6061.
“Oh, 6061 and 7075,
Which one should you pick for your yo-yo dive?
Let me tell you, dear friend,
The differences between the two, from beginning to end.
6061 is lightweight, oh so true,
With complex shapes, it’s easy to do.
It won’t cost much, and that’s a plus,
Making yo-yos affordable for all of us.
7075 is strong, oh my,
It can take wear and tear and never die.
Yo-yos made with it will last and last,
But they may be heavier, so spin time might not be as vast.
So, which one to choose? That’s up to you,
Think of your playstyle, and you’ll know what to do.
For light and fancy, 6061’s your call,
For durability and strength, 7075 stands tall.
Now, go pick your metal, and yo-yo away,
Having fun, whether at work or at play”
Yeah not mentioned here is that 7068 has the benefit of taking ano better while maintaining much of the increased durability/hardness properties of 7075.
Also of note is that material alone is somewhat meaningless without design. A design made in 6061 that was just made again in AL7 with no changes to design might play worse! Typically you also maximize the design elements to fit the material (like thinner walls).
Very cool that the AI basically gave a really educated answer though!
Interesting how ChatGPT has ignored the fact that 7075 has slightly more density than 6061. That is the real difference when designing. That may be where the stability comment comes from.
ChatGPT only ignores things that are newer than mid 2021. The density difference must be a recent development because we all know the AI can’t be wrong…
