Aluminum 713.1
Aluminum 713.1
(OP)
Gentlemen, for those of you in aluminum, We've pouring 355.0 and 356.0 for for many years now, and I'm familiar with melting, processing, etc. of these alloys.
Recently, we got an order for parts cast in 713.0 (parts investment process, casting wt. .75 lb, wall thickness .375''). I have to get it right the fist time.
No time for trial and error. Are there special precautions I should take as far as melting, pouring, degassing, etc. since 713 is different than 356 for example?
(Similar but different). I researched internet and literature regarding the subject but didn't come across any stuff I didn't already know.
Any information would much appreciated.

RE: Aluminum 713.1
What material/process specification [ASTM, AMS, ISO, etc?]?
What temper?
Why no trial runs... this is a set-up for Your failure...??

NOW... all You have to do is verify casting quality by RANDOM selection of sample parts [% determined based on production quantity] from the actual production lot... for dimensional inspection and nondestructive inspection and destructive testing and metallurgy chemistry/examination... and then stick to a regimen of suitable inspections/NDI for the remaining [customer] parts of THAT cast-LOT...AND THEN You'll have success.
