Cast Aluminum Shot
For applications requiring a smooth bright metallic finish, free from ferrous contamination.
Long life, low dust blast media
RSA cast aluminum media is gentle enough to protect delicate gasket surfaces and critical date coding information; yet aggressive enough to de-flash and de-burr light metal castings and clean rust, scale or corrosion from remanufactured parts.
RSA-319 alloy cast aluminum media is our most popular; combining an ideal blend of hardness and durability. With an average cycle life of 8000 cycles* it outlasts stainless steel by almost two times and glass bead or plastic media by as much as 1000 times.
Applications include finishing castings, profiling for coating & lubrication adhesion, blast cleaning parts during remanufacture, refractory mold release removal from dies, and more.

RSA-(2N) is made from very pure aluminum and is significantly softer than the 319 alloy listed above and not as aggressive. It is used on very delicate surfaces where a very smooth finish is desired. Average cycle life is 14,000 cycles.*
