All of them. We can supply the products according to the customer's drawings, samples and performance requirement.
Sample delivery in 4 to 7 working days. Production is 15 to 30 days if the goods are not in stock, according to the dimension and quantity.
We offer the sample free of charge but do not pay the cost of freight.
We inspect according to your drawings and issue an inspection report, and provide photographic documentation of the packing and shipping process.
95% and 99% alumina rings, tubes, substrates and plates for insulation, wear and high temperature service up to 1650C.
See the rangeTalc based steatite beads, strips and insulators for electrical heating assemblies where dielectric strength matters more than toughness.
See the rangeMo/Mn metallized and plated alumina ready for brazing into vacuum interrupters, feedthroughs and hermetic assemblies.
See the rangeSilicon carbide rings, cylinders and seal faces for abrasive slurry and hot gas duty where alumina wears through too quickly.
