A rough guesstimate would be 75% aluminium and 25% steel. I'm able to source a large amount of both aluminium and steel swarf, so if you'd like to purchase in bulk then a good deal can be made on eBay. This product is a 5+kg pack of aluminium and steel swarf metal shavings, sourced from a family run company in Shropshire, England. Ideal for arts and crafts projects, this resin orgonite DIY material can be used in a variety of creative ways. The metal shavings add a unique touch to any crafting project, allowing for endless possibilities in design and innovation. Made from high-quality materials, this product is perfect for those looking to add a touch of metal to their crafts.
