Notes:

(1) Coefficient to be multiplied by 10-6. Example: 12.2 x 10-6 = 0.0000122.

(2) Melting ranges shown apply to wrought products of 1/4 inch thickness or greater.

(3) Based on typical composition of the indicated alloys.

(4) Eutectic melting is not eliminated by homogenization.

(5) Eutectic melting can be completely eliminated by homogenization.

(6) Homogenization may raise eutectic melting temperature 20-40 °F but usually doesnot eliminate eutectic melting.

Notes:

(1) Based on 500,000,000 cycles of completely reversed stress using the R.R. Moore type of machine and specimen.

(2) Average of tension and compression moduli. Compression modulus is about 2% greater than tension modulus.

(3) Tempers T361 and T861 were formerly designated T36 and T86, respectively.

(4) Up to 2 inches in diameter.
