Graphite Sphere

Chengdu Artech Specialty Graphite Co.,Ltd is one of the leading China graphite sphere manufacturers and also a professional graphite sphere supplier,Website:http://www.artechgraphite.com, welcome to import products from our factory.Product name: Graphite sphere                         Graphite sphere for high temperature and vaccum furnace             Material: high pure graphiteSize: customizeApplication: high temperature and vaccum furnaceDensity: 1.65-1.88 g/cm3Compressive strength: 30-240MpaFlexural strength:7-85MpaSpecific electrical resistance:6.5-15μΩmBrand Name: OEMMOQ: 1 pcsDelivery date: 20 daysPackage: Polywood or custom packageFunction:1.Graphite sphere have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .2.Graphite sphere have good electric conductivity.As temperature rises, electrical conductivity increases. 3.Graphite sphere have high thermal conductivity.The thermal conductivity of graphite is higher than that of manymetals and falls with increasing of temperature. 4.Graphite sphere can resist thermal shock. so rapid heating or cooling is not a problem.5.Graphite sphere can resist corrosion.It can be widely used in acid based environments.6.Graphite sphere are not wetted by molten glass or by most molten metals.7.The tensile,compressive and flexural strength of graphite sphere are very high.8.Graphite sphere have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for thefinished items.
