I bought some Elforyn from Atlas a couple years ago. I used it on a couple knives. It is very easy to work because it's softer than I expected. I wouldn't call it an ivory substitute as I'm currently working with some interior mammoth tusk and it is a very different material. Overall I doubt I'll use the Elforyn again, although it sure is a lot cheaper and not prone to cracking.I haven't heard of armorin, but Atlas Billiard supply carries an ivory substitute called Elforyn in blocks.
They may be able to help you.
