SR319-T51 Specifications

SR319-T51 Specifications

(OP)
I'm trying to track down any information about SR319-T51. Any information would be appreciated.

RE: SR319-T51 Specifications

Could you supply more information about the designation? 319-T51 would refer to a permanent mold 319 alloy casting that is artificially aged (i.e. no solution treatment). But the SR prefix is one that is not known to me.

RE: SR319-T51 Specifications

Thanks Swall! You're correct in that it is a permanent mold Aluminum casting. The SR prefix is something I could find only in a brochure of Harmony Castings. www.harmonycastings.com/techdoc.pdf is the link where you can find reference to this. Hope this helps.

RE: SR319-T51 Specifications

The "SR" could indicate a strontium modified casting. Addition of small amounts of strontium causes the hypoeutectic silicon particles to become much finer than in a non-modified casting and this will increase mechanical properties somewhat.
