Some common blasting abrasives are listed below. All abrasives have benefits and drawbacks such as quality of surface finish, abrasive life, toxicity, and what precautions you must take to prevent environmental damage or personal injury to your respiratory system.
Steel Type Abrasives
This aggressive abrasive creates a rough fin- ish that accepts paint well. The abrasive is very durable and has a long life; however, it MUST be kept very dry to prevent rusting.
Alumina Type Abrasives
This
Glass and Garnet Type Abrasives
Typically this abrasive works well for soft metals and addressing surface issues with equipment parts where tolerances cannot be affected. The life of this abrasive is limited and not well suited for repetitive recycling.

has a good recycling life and is very economical.
