Anyone ever try one of these? What kind of alloy is it? Does anyone still make the steel impellers? _________________ It was like that when I got there! |

Never heard of it. Roger Kehoe is still building steel ones. I thought a while back somebody was gonna build or cast a titanium impeller ?? |

Aggressor uses it. It is a type of alum. It is quite a bit harder than alum but also way more brittle. Family boat maybe but definitely not a race boat. |

Here is a link that compares strength of various Aluminum sand castings.
http://www.alcast.com/material_specs.htm
Items cast from Tenzalloy Alloy #713 offer greater strength and corrosion resistance than Almag 35 which is the most common alloy for marine aluminum "things". (I do not know the aluminum alloy used for most impellers-most just say "Aerospace aluminum casting, heat treated and coated".) Tenzalloy increases in strength as it ages. _________________ "faster, Faster, FASTER until the thrill of speed overcomes the fear of DEATH"#163 "Tuff-n'-Nuff" |
