looking for specific grade of aluminum, anticorodal-100

i am working for a european scientist who requires <br>
a grade of aluminum only found in europe. the material <br>
is anticorodal-100. the composition, i think, is AlMgSil. <br>
do you have a material with these specifications? i need <br>
two rounds, 6&quot; dia. x 1&quot; thick.<br>
i've been informed that this material is called 6063 here<br>
in the u.s. and it is an extruded material only. so now <br>
i'm looking for tube shapes, 6&quot; o.d. x 1&quot; wall, and <br>
4.5&quot; o.d. x 1&quot; wall<br>
