Alumaloy

OK, so just thinking about this product.Alumaloy. It appears to have good reviews. Has anyone tried this? So I was thinking if someone wanted to raise the compression of there saw, they could melt some of this onto the piston.Appears to work wonders on most aluminum products.From what I was able to understand it has a melting point of 850 degrees. From propellers, to ladders, boats,radiators. Anyway I was just wondering if anyone has used this. Ken

Seems to work well for many applications but a blob of it on the top of a piston would make me very nervous...

If I were to try it, I'd make it thin like a machined stock piston popup, as opposed to an 028 super style dome.

It looks interesting and the specs aren't too bad. The website lists the melting point as 728°f. I'm not sure if that's high enough to
withstand a working saw on a hot day.

I'd be tempted to try it in a cheap clamshell engine first to stress test it.

I don’t think it would work, aluminum melts at 1221°and two strokes run there best near the melting point, this was on bikes, but the good running bike can be 900°-1100° egt’s

I’d afraid that it might melt off and cause a catastrophe.

I had the same thoughts you did and bought the 1000* alloy. I wanted to use it for exhaust roofs, not pistons, and was given the same advice the guys above are giving you.

Using it on the cylinder you may get away with, plenty of thermal mass/heat sinking and no vicious reciprocation trying to tear it off.
