What is the d50 value?
The d50 indicates the mean particle size. d50 means that 50% of particles fall within the specified grain size.
White Fused Alumina FEPA Size
White Fused Alumina FIPA size sand is made of high-grade industry alumina powder and smelted in an electric arc furnace at more than 2000 degrees. After full cooling and crystallization, it is broken, shaped, magnetically separated, and screened into various particle sizes. The general particle size are F4, F5, F6, F7, F8, F10, F12, F14, F16, F20, F22, F24, F30, f36, F40, F46, f54, F60, F70, F80, f90, F100, F120, F150 F180、F220、F230、F240、F280、F320、F360、F400、F500、F600、F800、F1000、F1200. There is a certain correlation between its chemical composition and particle size.
White Fused Alumina FEPA Size（FAQ）
Form and shape of the abrasive:
This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the abrasive will be used for hand. sanding, applied to a large disc
What’s lead time for bulk order?
1)for 5~25 tons, it takes around 10~15days. 2)For 26~200 tons,20-40days We will try to deliver it with the promise of quality guarantee as soon as possible
What is the refractive index of white fused alumina compared with that of glass?
The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).
What does the bulk weight indicate and what impacts the bulk weight?
According to the FEPA, the bulk density of an abrasive is the quotient of the mass and the volume a grain type poured out in a particular manner will occupy. The bulk density, also called bulk weight, is stated in g/cm3. The rounder the particles, the higher the packing density,
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.

How is fused alumina obtained?
Raw materials containing aluminium oxide are electrothermally melted at a reaction temperature of more than 2,000 °C to produce the various fused aluminas. Different starting materials are used depending on the desired type of fused alumina. For instance,
