Product Details

High Strength Ceramic Si3N4 Silicon Nitride Valve Ball

 

PRODUCT DESCRIPTION

 Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical  ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal  shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination  of creep and oxidation resistance and high strength. Additionally, its low thermal conductivity and high wear  resistance make it an excellent material that can withstand the toughest of conditions in the most demanding  industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are  needed.

 Key Applications of Silicon Nitride

 

 Automotive: Bearings, Tappet Shims & Buckets, Cam Rollers, High pressured pumps parts, Turbocharge Rotors,  Rocker arm tips, Welding location pins, Squeeze Rollers for radiator tube manufacturing etc. for its superior  mechanical reliability and wear resistance and corrosion resistance

 

 Balls & Bearings: Fully dense various size balls from o.5mm up to 50mm OD, Fully dense ceramic Bearing, Roller  Bearing, Tapper Roller bearings & Plain Bearings for 60% lighter weight, electrical- magnetic insulating, 70% higher  speed, chemical resistance, high temperature etc. Also Hybrid bearing having ceramic Balls & rollers for high  strength

 

 Non-ferrous Foundries: Thermocouples sheaths, Riser Tubes, Heater Tubes, Valve rods, Valve seats, aluminium  powder atomizer tubes, Molten metal pumps parts, Rotor for de-gassing shaft, Launders due to high temperature  capacity, excellent thermal shock, non-wetting properties

 

 CMM: Various types of styluses, styluses rods, Plain bearings, Ceramic balls etc.

 

 Oil & Gas Industries: Sleeves, Plungers, Needles, compression Rings, seals etc. are used for the harsh  environment  produces chemical, wear, corrosion and high temperature challenges that can be met through the use  of dense  silicon nitride

 

 Nuclear & Defence: Due to lightweight, hard wear and toughness, this advanced ceramic are used as a were  resistance tiles, impact plates, discs, ring etc. and also used for personnel body armors, vehicle, vessel, helicopter  and aircraft etc. applications

 

 Electrical & Electronics: A large variety of high performance parts are manufactured for the electrical electronic  industry due ti insulating and non-magnetic properties. Parts include wafer processing components, microwave  specialty ceramics etc.

FAQ
 Q1: What are advanced ceramics?

 >>> Advanced ceramics - also referred to as engineering, structural or technical ceramics - have been processed to  be very pure and, in general, have superior properties to unrefined ceramics. Many are man-made, i.e. they do not  occur naturally, e.g. silicon nitride, and their properties can be enhanced to produce very high strength at high  temperatures, good corrosion resistance, etc.

 Q2: What types of ceramic do you supply?
 >>> Alumina in purity from 90% to 99.7%, yttria stabilized zirconia (Y-PSZ), hot pressed boron nitride, machinable  glass ceramic, boron carbide, silicon nitride, mullite and cordierite.

 Q3: Can I machine the ceramics myself?
 >>> The harder ceramics like alumna and zirconia will require diamond tooling but other materials like Machinable  Glass Ceramic and Hot Pressed Boron Nitride can be machined. To get the right result it does take time, experience  and semi-specialised tooling but it can be done and many of our customers take advantage of this when they need  extremely fast solutions in-house.

 Q4: Can I get a sample or purchase a small quantity?
 >>> Yes, we are happy to supply small samples of material for you to test. We can also supply prototype quantities  through to volume production to suit your needs.

 Q5: How long will it take for you to send me a quote?
 >>> This depends totally on the complexity of your requirements. For simple items such as bars and rods, we can  generally supply a quotation within 24 hours.

 Q6: What's the delivery time?
 >>> For our standard products, like ceramic protection tubes and insulating rods, delivery time is normally 7 working  days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized  products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30 working days.
