Frequently Asked Questions
What does G3P black media mean?
G3P black media is a chrome-corundum based media bonded with metal binder, giving higher strength and density for efficient polishing of hard metal parts.
Why is it not suitable for soft workpieces?
Its high density and cutting action can be too aggressive for soft materials. Use a gentler media such as walnut shell or resin media for soft alloys and delicate parts.
Can it combine rough and fine polishing?
Yes — G3P black media is designed to perform rough, moderate and elaborate polishing in a single process, saving cycle time.
