Mixed Grade Bubble Alumina

Bubble Alumina has the characteristics of lightweight, closed holes and high-temperature resistance. Industry alumina powder melting through the electric arc furnace, blowing and instantaneously cooling in air. It is used to produce lightweight insulating refractories where the prime requirements are low thermal conductivity and high-temperature properties. Alumina Bubble is also used effectively for loose-fill refractories, low density, high insulation refractory castable, or concrete, or to produce ceramic bodies useful in applications up to 1800°C.

Mixed Grade Bubble Alumina(FAQ)

What is corundum?

Corundum is a mineral from the category of oxides and hydroxides and is the most frequently used industrial mineral worldwide. It also occurs naturally as a gemstone (sapphire, emerald, ruby). Chemically corundum is aluminium oxide with the chemical formula Al2O3.

How do i know what abrasive is best for my application?

An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media Selection Guide to choose the most appropriate abrasive for your application.

What is the hardness?

Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest.  A weak bond is preferred for grinding harder materials while  a stronger bond is desired for softer materials.  A typical weak bond for steel would be in the ‘F, G or H’ range.  A

Can i get sample in free , how long is the time?

Yes, certainly. We will provide the sample is in free below 5 kgs for free, and the freight cost for free in 1kg. We could arrange the existing samples express delivery immediately. For any special samples requirement, it need max 7 days finished. Usually we send samples by TNT ,FEDEX,

What is the best way to store my abrasives?

The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a
