Abstract:

A test program was conducted to obtain mechanical properties data on two aluminum casting alloys. Work included tensile, creep, and rupture tests at room temperature, 300, 400, 500, and 600F. The alloy, Hiduminium RR-350 was developed as a high temperature alloy. Its room temperature properties were moderate but it held its strength quite well up to 600F. The alloy CH-70 was developed as a high strength, high performance alloy in the 60,000 ultimate tensile strength, 50,000 yield strength, and 5 elongation range. Tensile properties of CH-70 held up well at the 300 test temperature but decreased rapidly at higher temperatures.
