206 Aluminum

206 Aluminum

(OP)
Greetings;  I machine an item that is cast as 206.0 in a T4 condition. Would the parameters of A206.0 or 206.2 lend themselves as suitable replacements for the 206.0?  thanks.

RE: 206 Aluminum

Aluminum alloy A206 is just a higher purity version of 206: Silicon is 0.05 instead of 0.10, Iron is 0.10 instead of 0.15, etc.  The .0 or .2 after the alloy designation merely indicates the product form to which the composition limits apply; .0 is for final casting products, either Sand or Permanent Mold type, and .2 is for the initial Ingot form.  The limits I gave above are for the .0 grades.  So, the answer to your question is yes.  The higher purity grade will have fewer secondary phases and inclusions, which results in improved dynamic properties like fatigue strength and fracture toughness.
