How to Choose Brown Fused Alumina for Steel Ladle Lining
A steel ladle lining holds molten steel, takes direct slag attack at the slag line, cools between heats, and then does it all again. Choosing brown fused alumina for it comes down…
How to Choose Sanding Disc Grit Size for Weld Blending
Weld blending is the job that exposes a poor grit choice faster than any other coated-abrasive work. Knock the weld down too aggressively and you gouge the base metal; blend too…
How to Choose Brown Fused Alumina Grit Size for Metal Cutting Discs
A cutting disc is the least forgiving bonded abrasive there is. It is thin — often just 1.0 to 1.6 mm of resin-bonded grain — and it works at full speed the moment it touches…
How to Choose the Right Brown Fused Alumina Grit Size for Stainless Steel Sandblasting
Pick the wrong grit size for stainless steel sandblasting and the job punishes you twice: a profile too rough shows through thin coatings on visible stainless parts, and a profile…
How Brown Fused Alumina Is Made: From Bauxite to Grain
Every grain of brown fused alumina — whether it ends up in a grinding wheel, a sandblasting cabinet, or a refractory castable — begins as ordinary rock and passes through one of…
