Unfortunately, we only carry this size of rivet in the stainless steel variant you have viewed. Aluminum rivets cannot be used in hearth product fabrication, as they can deform due to excessive heat.
Aluminum rivets can usually be purchased from a home improvement store or from an HVAC supplier, as they are commonly used to assemble duct work. I apologize that we do not carry this product.
