Casting alloysA356 vs 6063
Casting alloysA356 vs 6063
(OP)
Hello To All
We recently had some cylinder heads sandcast that was supposed to be A356 alloy. While inspecting some other castings with a touch Spectrometer we discovered that the casting house has used 6063 instead.
How screwed are we? We have roughly 1000 hours of machine work in 4 heads
Thank You

A 356 is a good alloy for thin section, leak tight castings. It also provides
good corrosion resistance. End uses include cylinder heads, blocks and wheels. 6063 alloy, is not generally use for cylinder heads. Design engineer selected 356 alloy for a reason. I would ask the foundry, why your parts got casted in incorrect alloy? Something must have gone wrong. The heat went out of control.. lol. Also, your customer may not be to happy about the whole situation. Having said that, you may be screwed.
I'm attatching a file, so you can review/compare properties and applications these two alloys.

It will not read silicon content. So the scan defaulted to the nearest material. We sent a sample to a certified lab and it came back as A356
Thank You for your time
