6061-O Aluminum vs. 6061-T6 Aluminum

Both 6061-O aluminum and 6061-T6 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.

For each property being compared, the top number is 6061-O aluminum and the bottom number is 6061-T6 aluminum.

When companies boast about using 6061 Aluminum there's a probability that they may NOT be using the top quality T6 grade, if they were they would more than likely state it.

FBO Billet distributors are all manufactured using 6061-T6 high quality Aluminum

Our Limiter bushing are made from a proprietary composition of an even higher grade of aluminum usually found in the manufacturing of high quality precision commercial aircraft components.
