Brown Fused Alumina

When it comes to good value for money, brown fused alumina is the first choice among the angular mineral products. As well as its high hardness, brown fused alumina is also noted for its extreme toughness which gives this iron-free blasting medium and abrasive extremely high stability. We will be happy to help you…
