In another thread it was posted that Tenzalloy was "Higher Tensile, also a tougher strength by 8,000 to 12,000 over 356 T6"
THAT'S JUST NOT TRUE
Here are the true facts.
356-T6 Ultimate Tensile (ksi) 40 Yield Strength 30 (ksi)
Tenzalloy Ultimate Tensile (ksi) 34 Yield Strength 23 (ksi)
Anyone that wants a copy of "Typical Mechanical Properties of Cast Alloys"
give me a call I'll send you one out.
