I am looking for a specification fo 3

[etch]

I am looking for a specification for EN AC-AL Si12(b) Aluminium casting alloy.

its roughly
Cu 0.1
Mg 0.1
Si 10.5 - 13 ish
Fe 0.5n 0.1

But would like somone to verify this and where they obtained the information. i have tried MATWEB

Reply to self, its okay you cant help it if your dumb. Its okay I found the spec. thanks anyway. Can i vote myself a red star?

Can you tell me where you find the spec. a web resource?

http://csnmt.fme.vutbr.cz/informace/cs/nezelezo/Aschen.htm

this site lists most euro aluminium alloys, one of the better sites. There is also

http://www.matweb.com

, this is good but sometimes is missing even the most fundemental alloys.

Dear Etch,
The source for this alloy spec is EN 1706 year 1998 which replaces the previous DIN1725 for the material specification for Aluminium alloys.
The Numerical designation for the alloy in EN AC 47000.
The spec is Si 10.5-13.5%
Fe0.8(0.7)
Cu1.0(0.9)
Mn 0.05-0.55
Mg0.35
Cr0.1
Ni0.3
Zn0.55
Pb0.2
Sn0.1
others 0.05 each
others 0.15 total(Figures in bracket indicate percentages in ingot )
This is an alloy equivalent to LM6 and is the alloy nearest to eutectic temp around 576C.Can be used where pressure tightness is required.
Hope the information is enough.
