china high quality new silicon carbide with low price

Product name

Abrasive black silicon carbide/Carborundum

Company name

Shouguang Yuanye ferroalloys &materials Co., Ltd.

Source area

    Henan,China

Description

• Black silicon carbide is produced in an electric-resistance type furnace through fusing quarts sand and petroleum coke and high quality silica with high temperature. Its hardness is between fused alumina and diamond's. 
• higher mechanical intensity than fused   
• It is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide, metallic, sic≥95%, stronger than green silicon carbide but softer than green silicon carbide, is mainly used for grinding of cast iron and non-metallic materials.

Advantage

1. 1.   Raw materials are of high quality: pure silicon carbide, guaranteeing the products’ good quality.
2. 2.   Sharp knife-edge, having cutting function.
3. 3.   Centralized and uniform particle size distribution
4. 4.   Electrical conductivity
5. 5.   Heat conductivity
6. 6.   Chemical stability
7. 7.   High thermal conductivity
8. 8.   Low expansion coefficient
9. 9.   Good abrasion-resistance

Parameter

• The shape: polygon
• Color: black
• Proportion:3:2
• Mircohardness:2840-3320g/mm2

Usage

• Black silicon carbide, sic≥98.5%,its toughness is better than green silicon carbide.
• Mostly for processing low tensile strength of the materials, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
