Product Description

6151 alloy T6 T652 aluminum forgings are generally used for forging crankshaft parts. Machine parts and rolling ring conducting mine and machine parts have good forgability, high strength and corrosion resistance. All parts requiring good forging performance, high strength and good corrosion resistance can be processed with this alloy.

Process characteristics

The annealing standard of 6151 alloy is 413ºC/(2h~3h). The cooling rate of 6151 alloy is not more than 27ºC/h. The alloy is cooled to 260 ºC with the furnace, and then air-cooled out of the furnace. Solid solution treatment temperature (510ºC~525ºC)/4min, quenching in room temperature water, quenching in 65ºC~100ºC water for large forgings. Artificial aging code(165ºC~175ºC)/(8h~12h). The hot working temperature ranges from 260 ºC to 480 ºC.

Mechanical property
The minimum mechanical properties of 6151 alloy are 50mm or 4D (d is sample diameter). 6151 alloy has no low temperature brittleness and can be used to process parts working at extremely low temperature. At 25 ºC, the tensile strength Rm = 330N/mm2, yield strength Rp0.2 = 298N/mm2, elongation A = 17%, and temperature drops to 200 ºC, the properties of 6151 alloy increase completely, reaching 395N/mm2, 345N/mm2 and 20%, respectively. The working temperature of 6151 alloy should not exceed 120 ºC.
