Is brass a good option for a burial urn if I am on a tight budget?

Hi, my dear brother was a dah and managed to die before me. Both our parents died when we were children and none of s ever had much money. As I result, I'm the only one, and I'm left to figure out how I am going to get my brother a burial urn without putting myself out of house. When I looked up affordable burial urns, I found a lot of brass ones. They're quite beautiful too. Will a brass urn be non-corrosive and withstand the weather elements? Would the design of the burial urn also impact the price?
