Iron Metal Powder (Atomized)

High purity atomized iron metal powder ideal for cold cast resin casting to create authentic solid metal finishes. Finished castings replicate the appearance and weight of real iron, can be polished or patinated, and easily produce realistic rust effects. A cost-effective and faster alternative to traditional foundry casting.
