Product Description

High qulity Black Fused Aluminium/Low Aluminum Corundum for surface treatment

PRODUCT  DETAILS                                                                                           


1. Black Fused Aluminium

Black fused aluminium is also known as low aluminum corundum.



It is also a new type of product on the based of producing brown fused alumina. And it is a dark gray
crystal body made α- Al2O3 and iron oxide as main ore in the electric arc furnace by smelting the bauxite.



Black fused aluminium is characterized by low Al2O3 and a certain amount of Fe2O3 (10% more or less) content,
so it has characteristics of moderate hardness, high toughness, high temperature resistance, and stable thermal stability.






2.  Black Fused Aluminium Application

Product Characteristics: 
^  Strong cutting power, High toughness, High flexibility
^  Good abrasion resistance and High working efficiency
It is the best product for grinding and polishing, sandblasting stainless steel products.  

Applications:
^  Mainly for polishing and sandblasting of stainless steel, fabricated metal products, optical glass,
    bamboo products

  

^  Also as new abrasive for manufacturing resin grinding wheels, cut-off wheels and emery cloth.

 

^  Mainly suitable for free grinding, such as coarse grinding before electroplating products.

Economical Grade	<80	>9	>8	>4

4.  Production Technical Process

The smelting method of black corundum is basically the same as that of brown corundum.

^  The production method of black corundum is to select high-quality bauxite, iron oxide and other
     raw materials, adding other trace elements, and then carefully smelted by tilting arc furnace. 

^   It ensures that the massive black corundum produced by smelting is premium grade, with few 
     impurities, high grade and stable quality. 

^   It lays the foundation for producing segment sand, particle size sand and micro powder with 
     moderate hardness, good toughness and good performance.



5.  Package & Shippment

^   25kg/bag, 1000kg/JUMPO bag ; Customerization Allowed.

^   After confirmation of cargo in good condition(packing sound), the cargo can be loaded 
     in CONTAINER, then sealing the container and finally starting shipping from loading port.

^   You will be receive the bulk products at your destination port after about 7- 20 days.
