This is about obtaining the titanium atoms - i.e. raw ore, not alloy. Even if it were about alloy, it wouldn't have matter that much what alloy Soviet provided

This is about obtaining the titanium atoms - i.e. raw ore, not alloy. Even if it were about alloy, it wouldn't have matter that much what alloy Soviet provided, as long as it contained enough fraction of titanium in it that US could refine. US wouldn't have bought it if it didn't contain enough titanium, thus this comment is nonsensical.
