Insulation Zirconia Ceramic Guide Blocks Connector Seat With Holes
keywords: ceramic guide block
Another superior quality of the ceramic guides over Cool Blocks is the hardness. SpaceAge Ceramic Guide Blocks are rated at 9.5 hardness on the Mohs Scale – almost as hard as industrial diamonds. This obviously makes them more impervious to wear than fiberglass phenolic, which is what Cool Blocks are made of.
Most home workshop hobbyists will never need to replace their SpaceAge guides.Our commercial clients order from us more often but our ceramic guides last longer than cool blocks guides do because of the material used. In “Bandsaw Fundamentals” (page 30) you will find a review on each type of block and ceramic blocks beat out Cool Blocks in terms of longevity.
Produce and machining
We can produce different sizes and shapes of the sheets for specific applications to different custom products.Such as drilling, polishing, stripes, concave and convex, screw holes, metal parts position and so on

This ceramic guide block is characterized by its extremely high strength and thermal conductivity. The outstanding surface quality on both sides makes it the perfect companion for any commercial thick film paste and even makes it suitable for a number of thin film applications (sputtering).
With its extremely fine surface quality, Small Ceramic Block Ceramic Block Insulation is designed especially to meet the highest demands in thin-film technology.
Small Ceramic Block / Ceramic Block Insulation offers consistently reliable and convincing performance even when subject to high thermal and electrical loads in terms of its:
Thermocycling capability
Thermal shock resistance
Flexural strength
Surface quality
Thermal conductivity
Small Ceramic Block / Ceramic Block Insulation Features :
| 1) High hardness, high strength, high wear and chemical corrosion resistance, low expansion coefficient. |
Small Ceramic Block /Ceramic Block Insulation :
Alumina substrates can withstand high temperature and maintain high strength and hardness. Alumina plates also have superb performances in electrical insulation, high chemical resistance and low thermal expansion. We have various sizes of semi finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.
Small Ceramic Block / Ceramic Block Insulation Specifications
Refractory alumina ceramic substrate/ceramic plate is our main product.Misson can supply high quality alumina plates with competitive prices.
Very small and very large sized plates can be made.
Fine grinding can made tight tolerance.
High temperature and abrasive resistance is good
Quality assurance:
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
