Packing & supply
- Strapped bundles of ~1 MT
- Wooden pallets on request
- Heat number stencilled on each bundle
Storage & handling
- Store under cover; preheat ingots before charging to avoid moisture-related spitting.
- Charge cold metal into a partially filled bath for smooth melting.
- Degas and flux as per your foundry practice; expect low dross.
