Composite Ceramic BN-SZ Description

Boron Nitride Composite Ceramic BN-SZBoron Nitride is a kind of advanced synthesis ceramic that was sintered at a 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, making 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 separate 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.
