A blend of cast iron powder for sintering, melting, fire works and making hand warmers. Already blended with up to 5% graphite is ready for many applications. Includes some clumps that are naturally formed due to stacking pressure. Clumps can be removed by re-screening or can brake down by chopping or grinding if needed.
Particles are slightly coated to reduce the risk of over heating and fire in case of contact with water. If you are using this product for hand warmers, oxygen absorbers or rust effect, you must add small amount of a surfactant or detergent to the water in order to break the coating.
Please do not order large quantity of this product before testing and evaluation. For evaluation purpose, free samples are available in our office for pickup or you may purchase small quantity online that will be shipped to you.
