Composite Ceramic BN-SZ Description

Boron Nitride Composite Ceramic BN-SZBoron Nitride is a kind of advanced synthesis ceramic which was sintered in the high temperature and high pressure by BN powder. It has many excellent properties including high temperature resistance, high thermal conductivity, easy machining and good lubricity, makeing BN an outstanding material.

Boron nitride composite ceramic BN-SZ, using silicon carbide and zirconia as a bonding agent, improves the thermal shock resistance and wear resistance of the product. It is commonly used as a separation ring for horizontal continuous casting and a nozzle made of amorphous ribbon. These products have stable chemical properties, high thermal shock resistance, and high corrosion resistance. They are widely used in molten metal contact.

• Chemical stability
• Good wear resistance
• High thermal shock stability

The quality of these are great, and honestly, I just adore the quality of ACM's products.

At this point, I am most definitely now a loyal ACM customer.
