The nearest I can come to answering your question is that the Prefix "ER/R" on ER4043 refers to.
E = Electrode
R = Rod
ER = Electrode & Rod
Alloy designation 4043 Aluminum
ER4043
Page 42 describes it more in depth than that.

In all cases an electrode that meets the test prescribed in A5.10 AWS specification can be used either as an electrode or a welding rod, but the reverse is not always
true for a “R” classification aluminum “rod.” Hope that helps.
